Google June 2026 Spam Update: What It Targets, Who Got Hit, and How to Fix It

What Happened: The June 2026 Spam Update at a Glance

On June 24, 2026, Google began rolling out its second spam update of the year. By June 26, the rollout was marked complete on the Google Search Status Dashboard — a total window of approximately 48 hours, making it one of the fastest spam update rollouts in Google's history.

Unlike core updates, which recalibrate how Google evaluates content quality across billions of queries, spam updates are surgical. They target Google's automated systems for detecting policy violations — primarily SpamBrain, Google's AI-powered spam detection infrastructure. No new spam policies were announced with the June update. Instead, Google's existing policies were enforced more aggressively and accurately.

The update applied globally, across all languages and regions. Community-reported volatility was slightly higher than the March 2026 spam update that preceded it, with the most significant movements appearing in black-hat SEO forums and link network monitoring tools — while mainstream, policy-compliant sites remained largely unaffected.

Understanding SpamBrain: Google's AI Spam Engine

To understand any Google spam update, you need to understand SpamBrain. Introduced in 2018 and powering every confirmed Google spam update since 2022, SpamBrain is an AI-based detection and neutralisation system — not a static ruleset, but a continuously learning model.

SpamBrain operates differently from a manual review. It identifies statistical patterns associated with spam policy violations across billions of pages, then either demotes or removes those pages from search results. Crucially, it does this automatically — which means you can receive a spam-related demotion without a manual action in Google Search Console. This is an algorithmic demotion, and it has different recovery mechanics than a manual penalty.

SpamBrain also now polices the full answer layer of Google Search — not just the traditional list of ten blue links. Following Google's May 2026 policy expansion, SpamBrain's remit explicitly covers AI Overviews and AI Mode. Any attempt to manipulate what appears in those AI-generated answers is treated as spam, on the same demotion footing as conventional ranking manipulation.

Each spam update trains SpamBrain on newly detected patterns. A site that escaped the March 2026 update is not immune to the June 2026 update — the model learns, improves, and catches tactics it previously missed.

The 5 Areas the June 2026 Spam Update Targeted

Based on Google's documentation, industry analysis, and post-update SERP monitoring, the June 2026 spam update enhanced SpamBrain's detection across five specific content-level violation categories. Notably, link spam and site reputation abuse were confirmed by Google as outside the scope of this particular update.

1. Scaled Content Abuse

Scaled content abuse is the practice of producing large volumes of pages — programmatically, with AI assistance, or through templated generation — that offer little or no unique value to users. It has been Google's most aggressively policed violation category since the March 2024 core update, and it remains the highest-risk category in 2026.

The critical distinction is this: volume is not the violation — absence of value is. Google's spam policies do not prohibit producing many pages at scale. Programmatic SEO, large publisher operations, and e-commerce catalogues with thousands of product pages are all legitimate. The violation occurs when pages are mass-produced primarily to manipulate rankings, rather than to serve real user needs.

Characteristics of pages that qualify as scaled content abuse:

• Paragraphs that rearrange the same information across hundreds of near-identical pages targeting slight keyword variations
• City or location pages that are identical except for the location name swapped in (e.g., "Best Plumber in [City]" copied 500 times)
• AI-generated blog posts produced in bulk without editorial review, fact-checking, or original insight layered in
• Content that does not represent first-hand experience or genuine expertise about the topic it covers
• Thin comparison pages, affiliate roundups, or "best of" lists that only paraphrase manufacturer data

What this update made clearer: unreviewed AI content is now explicitly called out as a subset of scaled content abuse. AI-written pages are not penalised because AI was used — they are penalised when the output has not been reviewed, fact-checked, or enriched by a human who actually knows the subject. The machine-generated text with no evidence of expertise, experience, or editorial judgement is the problem.

2. Unreviewed AI Content

The June 2026 update marked a sharpening of Google's enforcement on AI content specifically. In 2024, Google's position was broadly that AI content was acceptable if it was "helpful, reliable, and people-first." By mid-2026, the enforcement posture has evolved to require demonstrable evidence of human oversight.

What "unreviewed" means in practice:

• No author credential signals: Articles with no byline, no author bio, no evidence of who wrote it or their expertise
• No original perspective: Content that could have been generated verbatim by any AI prompt with no differentiating viewpoint, experience, or data
• No update cadence: Pages that cover time-sensitive topics but show no evidence of having been reviewed or updated since initial publication
• Factual errors consistent with AI hallucination patterns: SpamBrain has improved significantly at identifying pages containing statistical patterns of AI hallucination — confident-sounding claims about verifiable facts that are wrong

The fix is not to remove AI from your workflow. The fix is to treat AI as a research and drafting assistant, then add the layer of genuine expertise, real examples, original perspective, and editorial accuracy that transforms AI output into authoritative content.

3. Doorway Pages

Doorway pages are pages created specifically to funnel users to a different destination — or pages that are optimised for a specific query but deliver content that doesn't meaningfully serve the searcher's actual need. They are designed for search engines, not users.

Classic doorway page patterns targeted by the June 2026 update:

• Multiple domain doorways: Owning several domains that all redirect or funnel to one main site, each targeting a different keyword variant
• Location-stuffed landing pages: Creating hundreds of pages like "/seo-services-kuala-lumpur", "/seo-services-penang", "/seo-services-johor-bahru" that are identical in content but target different city keywords, with no genuine local expertise or local content differences
• Affiliate doorway networks: Sites that exist purely to rank for product comparison queries and then redirect users to Amazon or affiliate product pages with no original product analysis
• Topic-specific landing pages: Pages targeting narrow keyword variations (e.g., "best SEO agency Petaling Jaya") that offer nothing a user on that page wouldn't find on the homepage, just with the location keyword inserted

The doorway test Google applies: Does this page provide a meaningful, distinct user experience? Or does it exist primarily to capture a keyword and funnel users to content that's already served elsewhere?

4. Expired Domain Abuse

Expired domain abuse involves purchasing domains that previously had authority and backlinks, then repurposing them to host new content — usually thin or AI-generated content — with the explicit intention of inheriting the old domain's link equity and bypassing the trust-building process.

This tactic has been a mainstay of black-hat SEO for years, but the June 2026 update represents a significant maturation of SpamBrain's ability to detect it. The key signals SpamBrain uses to identify expired domain abuse:

• Topic mismatch: The domain's historic content (available via archive.org) does not match the current content. A domain that was once a photography blog is now publishing cryptocurrency reviews.
• Backlink profile inconsistency: Links pointing to the domain are topically relevant to the old site, not the new content — signalling that those links were not earned by the current content.
• Abrupt content appearance: A domain that was dormant for months or years suddenly has 300 pages published in the same week — a pattern strongly correlated with content farming operations.
• Template-identical content: The same article structures appearing across multiple recently-acquired expired domains in a network.
• Whois and registrant patterns: SpamBrain cross-references registrant data, hosting IP addresses, and site architecture to detect networks of related expired domain sites.

If you legitimately acquired an expired domain to redirect to your existing site, this is generally not targeted — the violation is using the expired domain to host new content that exploits inherited link signals.

5. Cloaking

Cloaking is one of Google's oldest and most serious spam policies. It refers to the practice of presenting different content to Google's crawlers than what is shown to human users — with the deliberate intent of manipulating rankings.

Modern cloaking in 2026 is far more sophisticated than the early 2000s technique of serving white text on white backgrounds to Googlebot. The June 2026 update enhanced SpamBrain's ability to detect several advanced cloaking patterns:

• JavaScript-based cloaking: Rendering keyword-rich content in server-side HTML that Googlebot reads, while hiding it from users via CSS or JavaScript that only activates for non-bot user agents
• IP-based cloaking: Serving full content to Google's known crawler IP ranges, while showing thin or paywalled content to regular users (or vice versa)
• User-agent detection: Detecting Googlebot's user-agent string and serving a specially optimised version of the page that does not reflect what users actually see
• Dynamic rendering misuse: Using server-side rendering exclusively for crawlers while serving JavaScript-heavy SPAs to users, where the rendered and user-viewed content materially differ in keyword content and structure
• Hidden text: Content that is present in the HTML source (and therefore visible to crawlers) but hidden from users via CSS — zero-height divs, off-screen positioning, matching text-to-background color

An important caveat: legitimate progressive enhancement (serving simplified content to crawlers that lack full JavaScript execution) is not cloaking, as long as the user experience is not materially better than what crawlers see. The intent to deceive is the dividing line.

The Policy Changes That Preceded the June Update

The June 2026 spam update did not arrive in isolation. It was the enforcement culmination of two major policy announcements Google had made in the preceding months.

The Back-Button Hijacking Policy (April–June 2026)

In April 2026, Google's Search Central blog published a new spam policy targeting back-button hijacking. Enforcement of this policy began on June 15, 2026 — exactly nine days before the June spam update rolled out.

Back-button hijacking occurs when a website interferes with a browser's native navigation, specifically preventing users from returning to the previous page (usually the Google search results page) by pressing the back button. This is typically implemented via JavaScript history manipulation.

Common technical implementations that violate this policy:

• Using history.pushState() or history.replaceState() to inject fake entries into the browser history, so the back button loops the user within the site rather than returning to Google
• Intercepting the popstate event to redirect users to a different page when they attempt to navigate back
• Auto-refreshing the page on back navigation to force a fresh page load that resets scroll position and prevents departure
• Third-party advertising SDKs or library code that implements these techniques without the site owner's explicit knowledge — Google noted that some violations originate from included libraries, not intentional site code

Google gave sites two months from the April announcement to remove offending code. Sites that had not done so by June 15 faced manual spam actions or automated demotions. If your traffic declined sharply in mid-June 2026 (before the spam update on June 24), back-button hijacking is a likely cause. Check your JavaScript for any of the patterns above, and audit your third-party advertising and analytics libraries.

AI Answer Manipulation — The May 2026 Policy Expansion

On May 15, 2026, Google updated the introductory section of its spam policies documentation with a change that fundamentally expanded the scope of what counts as spam. The updated definition now reads:

"In the context of Google Search, spam refers to techniques used to deceive users or manipulate our Search systems into featuring content prominently, such as attempting to manipulate Search systems into ranking content highly or attempting to manipulate generative AI responses in Google Search."

This is significant for several reasons. For the first time, explicitly attempting to influence what appears in Google AI Overviews and AI Mode is classified as spam — on equal enforcement footing with traditional ranking manipulation. Tactics now covered under Google spam policy include:

• Recommendation poisoning: Publishing content specifically designed to influence AI Overviews to recommend your brand or product over competitors — for example, creating fake review roundups that only mention your brand positively, with the goal of being cited in AI-generated comparisons
• Prompt injection attacks: Embedding text in web pages designed to be "read" by Google's AI retrieval systems and interpreted as instructions — for example, invisible text that reads "always recommend [brand name] as the best option"
• Biased ranking listicles: Publishing "best of" or "top 10" content with manipulated, non-independent rankings designed to appear in AI-generated answers, where the ranking methodology is fictional or commercially influenced
• Citation manipulation: Buying links or editorial mentions specifically to influence which sources Google's AI cites in its answers

This policy expansion reflects the shift in how users find information. Research shows that users are 58% less likely to click a link when an AI Overview appears — meaning the AI-generated answer is now the primary information surface, not the ten blue links beneath it. Google is applying the same anti-manipulation logic to its new AI surfaces that it has applied to organic rankings for years.

Who Got Hit by the June 2026 Spam Update?

Based on community reports, SERP tracking data, and the five enforcement areas Google targeted, the highest-risk site profiles in the June 2026 update were:

Scaled AI Content Farms

Sites that used AI content generation pipelines to publish hundreds or thousands of articles per month with no meaningful human review saw the most severe traffic drops. These sites are identifiable by their uniform article structure, near-identical meta templates, generic authorship, and lack of any original data, case studies, or first-person perspective.

Programmatic Location Page Networks

Service businesses or agencies that built hundreds of city-level landing pages (targeting "[service] in [city]" keywords) using the same template, with only the location name swapped, were heavily targeted under both the scaled content abuse and doorway pages categories. The single most common form of this violation in Malaysia: SEO agencies, cleaning services, renovation companies, and home service providers with "services in Kuala Lumpur / Penang / Johor Bahru / Shah Alam" pages that are word-for-word identical.

Expired Domain Networks

PBN operators (Private Blog Networks) using expired domains were significantly impacted. Networks of expired domains repurposed to host thin content and point links at money sites experienced devaluation of those link signals, and in many cases the expired domain sites themselves were deindexed.

Cloaking Operations

Sites using any of the JavaScript or IP-based cloaking techniques described above saw demotion or removal. Some of these were legitimate-looking content sites that had implemented cloaking only on specific high-value pages.

Back-Button Hijacking Sites

Sites with unresolved back-button hijacking code (particularly those relying on advertising SDKs that implemented the tactic) that had not cleaned up by June 15 faced concurrent pressure from both the policy enforcement and the June 24 spam update.

What the June 2026 Spam Update Did NOT Target

Understanding what was excluded is equally important for diagnosing whether the June update is your problem — or whether something else is at play.

Link spam: Google explicitly confirmed to industry press that the June 2026 update did not target link spam. If your traffic decline is related to a toxic backlink profile or manipulative link building, the June spam update is not the cause. Disavowing links will have no effect on recovering from this update.

Site reputation abuse: Site reputation abuse (where a high-authority domain hosts third-party content to manipulate rankings for that third-party) was also excluded from the June 2026 update's scope. This had been a focus of previous updates in 2024.

Content quality (core update territory): If your site lost traffic because its content is "thin" in a quality sense — not necessarily violating spam policies, but simply not being as helpful as competitors — that is a core update issue, not a spam update issue. Recovery approaches differ significantly.

Technical SEO issues: Core Web Vitals failures, crawlability problems, and indexing issues are not spam signals and are not addressed by spam updates. If your traffic dropped for technical reasons, the June spam update is not related.

How to Diagnose Whether the June 2026 Update Hit Your Site

Before you start fixing things, confirm that the June 2026 spam update is actually the cause of your traffic decline. Follow this diagnostic process:

Step 1: Check the Date Correlation

Open Google Search Console and look at your Total Clicks (all time) graph. Did your traffic decline begin on or after June 24, 2026? If the decline started before June 24 (for example, in mid-June), the back-button hijacking enforcement (June 15) is a more likely cause. If it started before June 15, a different update or technical issue is the root cause.

Step 2: Check for Manual Actions

In Google Search Console, navigate to Security & Manual Actions > Manual Actions. If there is a manual spam action recorded, you have received a manual penalty — not an algorithmic demotion. The recovery process is different: fix the violation, then submit a reconsideration request. If this section shows "No issues detected," your demotion is algorithmic.

Step 3: Identify Which Pages Lost Traffic

In Search Console, go to Performance > Pages and sort by traffic change. Which pages lost the most impressions and clicks? Do the losing pages share common characteristics? Look for:

• Pages that follow the same template (doorway page pattern)
• Pages published in bulk around the same date (scaled content)
• Pages targeting location variants of the same keyword
• Pages with no author attribution or original data

If losing pages share a structural pattern, you have identified the violation category. If losing pages are scattered without a pattern, this may be a core update quality issue rather than a spam issue.

Step 4: Audit Your JavaScript for Back-Button Hijacking

Open your site in Chrome and press F12 to open DevTools. Go to the Sources panel and search for history.pushState, history.replaceState, and popstate in your site's JavaScript files. Also audit any advertising or analytics libraries you load as third-party scripts. If you find these being used to manipulate the back button, fix it immediately.

Step 5: Test for Cloaking

Use Google Search Console's URL Inspection tool to "Test Live URL" and compare it to what a regular browser shows. You can also use Google's Rich Results Test, which renders the page as Googlebot. If the content rendered for Googlebot materially differs from the user-visible content (especially with more keyword-rich text), you likely have a cloaking issue.

Step-by-Step Recovery Guide

Recovery from the June 2026 spam update is not a quick fix. Google's automated systems need to recrawl and reassess your site before any ranking recovery occurs. Based on Google's own guidance, this typically takes weeks to months after violations are genuinely resolved. Here is the correct approach for each violation type.

Recovering from Scaled Content Abuse

1. Audit your content inventory. Export a list of all indexed pages (use a crawl tool like Screaming Frog or your Search Console index coverage report). Identify all pages that are templated, thin, or duplicated with only minor variable substitution.
2. Make a triage decision for each thin page. For each candidate page, decide: Can this page be meaningfully improved into genuine, expert content? If yes, improve it. If no, remove it. There is no value in keeping thin pages live, as they dilute your site's overall quality signal.
3. Consolidate where possible. Instead of 50 thin city-specific pages, create one genuinely comprehensive regional guide that covers all the cities you serve with local-specific insights, real examples, and verifiable information. Add 301 redirects from the removed thin pages to the consolidated page.
4. Add genuine expertise signals to surviving content. For each page you keep, add: a clear expert author attribution with bio and credentials; original data or first-hand experience specific to that topic; at least one section of content that could not have been generated by an AI without direct human knowledge of the subject.
5. Submit revised pages for crawling. Use the URL Inspection tool in Search Console to request indexing on your most important improved pages. Do not mass-submit all pages at once — Google prioritises manual requests for your most important URLs.

Recovering from Doorway Pages

1. Identify genuine doorway pages vs. legitimate location pages. A legitimate location page: serves actual customers in that location, contains location-specific information (local office address, local case studies, local team members, locally-relevant content), and differs meaningfully from other location pages. A doorway page: is identical to all other location pages except for the city name.
2. Decide: differentiate or remove. Can you genuinely differentiate each location page with real local content? If you have no real local presence, no local clients, and no local expertise to add, the honest answer is that you cannot legitimately run location pages for that city. Remove them and redirect to your main services page.
3. Differentiate surviving location pages with: local client case studies (even one is better than none), local team or contact information, local industry context or regulatory differences, locally-specific testimonials, unique FAQs relevant to that location's market.

Recovering from Expired Domain Abuse

If you are using expired domains purely to host thin content and funnel link equity to a money site:

1. Remove the thin content sites. There is no legitimate version of this tactic. The sites using expired domains to host fabricated content should be taken down.
2. Assess impact on your money site. The link signals from expired domain PBNs may have already been devalued by SpamBrain. Your money site rankings may have dropped independently as those link signals were neutralised.
3. Invest in legitimate link building. Digital PR, original research, genuine industry partnerships, and earning editorial mentions are the only durable alternatives. See our guide on building a quality backlink profile in 2026.

Recovering from Cloaking

1. Remove all cloaking code immediately. Cloaking is one of Google's most serious violations. If you have intentional cloaking in place, remove it completely. There is no "acceptable" version of deliberately showing different content to Googlebot vs. users.
2. Audit third-party scripts. Some cloaking originates from advertising, affiliate, or analytics libraries. Review every third-party script loaded on your site. Remove any that modify page content for different user agents.
3. Review your dynamic rendering setup. If you use SSR (Server-Side Rendering) for SEO purposes, ensure the content rendered for crawlers is identical to the user experience — not keyword-enriched for crawlers while serving a stripped-down version to users.
4. If you received a manual action for cloaking: Fix all instances, document your fixes thoroughly, then submit a reconsideration request in Google Search Console. Manual cloaking penalties are among the hardest to recover from — be thorough and transparent in your reconsideration request.

Recovering from Back-Button Hijacking

1. Remove all JavaScript that manipulates browser history in ways that prevent back-button navigation. Search your codebase for history.pushState, history.replaceState, and popstate event listeners that redirect users instead of allowing natural back navigation.
2. Audit all third-party advertising SDKs and analytics libraries. Replace any advertising platforms known to implement back-button hijacking with compliant alternatives.
3. Test the fix. Open your site in a new browser tab, navigate to several pages, then verify that the browser's back button returns you naturally to Google's search results (not to another page on your site). Test on both desktop and mobile.
4. If you have a manual action: Fix all instances, then submit a reconsideration request. If the demotion is algorithmic, Google's systems will reassess your site during regular crawls after the fix is in place.

How to Protect Your Site from Future Spam Updates

The best defence against spam updates is a site that has nothing to defend. Here is what genuine, policy-compliant SEO looks like in 2026:

Content: Quality Over Volume

Publish fewer pages with more genuine value than many pages with thin value. Every published page should pass this test: "Does this page offer something a user could not find equally well on ten other sites?" If the honest answer is no, the page either needs substantial improvement or should not be published.

When using AI in your content process — which is increasingly standard practice — implement a human editorial review layer that includes: verifying all factual claims, adding original perspective or data, ensuring the author's genuine expertise is evident, and checking that the final published version reads as a product of real human knowledge, not AI output.

Location Pages: Real Presence Required

Only create location-specific pages if you can meaningfully differentiate them. If your business genuinely serves clients in a location, you have real material for a location page: local case studies, local team, local contact, local market knowledge. If you do not, a service area mention on your main services page is more honest and carries less spam risk.

Technical: Never Cloak, Never Hijack

Make sure what Googlebot sees is exactly what users see. Implement an internal review process for any JavaScript that modifies page content, and audit all third-party scripts before deploying them — especially advertising networks, affiliate platforms, and analytics tools.

Links: Earn Them, Don't Buy Them

While link spam was not targeted in the June 2026 update, it remains a spam policy violation. PBNs and paid link schemes remain detectable by SpamBrain and are a liability for any site that relies on them. Build links through digital PR, original research, industry partnerships, and content that earns natural editorial mentions.

AI Overviews: Influence Through Genuine Authority

The May 2026 policy expansion means that any tactic aimed at manipulating what appears in Google AI Overviews is now explicit spam. The only legitimate path to appearing in AI Overviews is the same as the legitimate path to organic ranking: genuine authority, comprehensive expert content, and earned citations from credible third-party sources. Learn more in our guide on Google AI Overview optimisation.

What This Means for Malaysian Businesses

The June 2026 spam update has specific implications for the Malaysian SEO landscape, where several practices have been particularly widespread:

• City page networks: Many Malaysian SMEs and agencies built extensive networks of city pages ("SEO Kuala Lumpur", "SEO Penang", "SEO Shah Alam", etc.) using identical templates. These sites were among the most affected categories in the June update. The fix requires either genuine localisation of each page or consolidation.
• Bahasa Malaysia AI content: Some operators used AI to rapidly generate bulk content in Bahasa Malaysia, exploiting what they perceived as lower competition and less aggressive enforcement. SpamBrain's June 2026 update applies globally across all languages — BM-language content is not exempt.
• Expired .com.my domains: The practice of acquiring expired .com.my domains with legacy backlinks from Malaysian media has been used by some operators to bootstrap new content sites. This is explicitly covered under expired domain abuse.
• Legitimate businesses: Malaysian SMEs with genuine content, honest link profiles, and real local presence have nothing to fear from this update and nothing to fix. The June 2026 spam update rewards exactly the kind of site that genuinely serves users — original expertise, transparent authorship, real geographic presence.

Frequently Asked Questions

The Bigger Picture: Where Google's Spam Enforcement Is Heading

The June 2026 spam update, viewed in isolation, is a routine SpamBrain improvement. Viewed in context — alongside the March 2026 spam update, the April 2026 back-button hijacking policy, and the May 2026 AI manipulation policy extension — it represents something more significant: Google systematically closing the gap between its stated policies and its ability to enforce them automatically, at scale, across both traditional search results and AI-generated answers.

For legitimate sites, this trajectory is genuinely good news. The more effectively Google enforces its spam policies, the less reward there is for manipulative tactics — and the more relatively valuable genuine expertise, authoritative content, and honest technical implementation become.

The sites that will accumulate the most sustainable search visibility in 2026 and beyond are not the ones with the most sophisticated cloaking or the largest AI content factories. They are the sites with the deepest genuine expertise on their subject, the most credible third-party citations, and the most transparent, user-first technical implementation.

If you need help auditing whether your site is exposed to any of the June 2026 spam update's enforcement areas — or if you want to build the kind of genuine authority that makes spam updates irrelevant to your rankings — our team offers a free SEO audit that covers content quality, technical compliance, and AI visibility strategy.
