Google's September 2026 spam update: why slots and poker sites need to fix their top pages and cut the duplicates

What was the September 2026 spam update?

Google released the September 2026 spam update on 24 September and, according to the Google Search Status Dashboard, the rollout was complete on 8 October. It applied globally and to all languages. At 13 days and 16 hours it was the longest of the four spam updates Google has run this year, as Search Engine Journal reported. The three earlier ones each finished in under three days.

Google did not name a target. PPC Land reported that Google said no policy changes came with the release and that link spam was not the focus. That points to content, which is where slots and poker sites carry the most risk.

Early data suggests the impact was wide. Search Engine Journal reported analysis by Diib of 32,569 websites, comparing 24 to 26 September with the same days a week earlier. The median share of visits from unpaid Google search fell from 34% to 31%, and 10% of sites lost half or more of that share, against 5% in the earlier period. Diib called it an early read rather than a verdict, and the data does not show which sites Google treated as spam.

Why are slots and poker sites especially exposed?

Slots and poker are two of the most repetitive subjects in search. Countless sites cover the same games, the same rules and the same bonuses, and many brands repeat themselves across their own sites too. Google's spam policies describe several patterns that are common in both niches:

• Thin affiliation: Google describes this as affiliate pages where "product descriptions and reviews are copied directly from the original merchant without any original content or added value". For a slots site, that is a review built on the game provider's description and specification sheet.
• Template content: Google warns about "cookie-cutter sites or templates with the same or similar content replicated within the same site or across multiple domains or languages". Hundreds of slot reviews with only the game name, RTP and paylines changed fit that description.
• Doorway abuse: Google defines doorways as pages "created to rank for specific, similar search queries", including "multiple domain names or pages targeted at specific regions or cities that funnel users to one page". State-by-state or country-by-country poker and casino pages that say the same thing are the obvious risk.
• Scaled content abuse: Google describes this as when "many pages are generated for the primary purpose of manipulating search rankings and not helping users". No matter how the content is created, it counts. Strategy hubs filled with AI-written variations of the same poker basics come under this.

Google even uses gambling as an example. Its expired domain abuse policy mentions "casino-related content on a former elementary school site", and its site reputation policy describes a low-quality "best casinos" page placed on a medical site.

Where do slots sites repeat themselves?

• Game reviews built from provider copy. If the description, features and specification table match the provider's press kit and every other affiliate, the page adds nothing new.
• Overlapping list pages. "Best high RTP slots", "highest paying slots" and "best payout slots" usually answer the same question with the same games. One strong page beats three competing ones.
• Separate review, demo and free play pages for the same game, each with near-identical text.
• Free spins and bonus pages recreated every month or for every operator, leaving expired offers indexed alongside the current ones.
• Provider and theme hubs, such as Egyptian, fruit or megaways slots, that repeat the same introduction and the same game cards.

Where do poker sites repeat themselves?

• Rules and basics. Many poker sites have separate pages for poker hand rankings, how to play Texas Hold'em, Texas Hold'em rules and poker for beginners, all explaining the same thing.
• Strategy articles on the same topic. Several posts on starting hands, bluffing or tournament strategy, written years apart, end up competing with each other.
• Room reviews and bonus code pages for the same poker site, each repeating the same welcome offer and features.
• Location pages. "Best poker sites" pages for every US state or country that swap the place name but keep the same list and copy.

Why do overlapping pages hurt rankings?

Having two pages on a similar subject is not spam on its own. The problem is what Google does with near-duplicates, and what happens at scale.

Google's guide to its ranking systems explains that when many pages are very similar, its deduplication systems "show only the most relevant results to avoid unhelpful duplication". If a poker site has four pages chasing "poker hand rankings", Google will usually pick one, and it may not be the best one.

Overlap also splits the value a site has earned. Google's documentation on consolidating duplicate URLs says consolidation lets search engines combine signals, such as links, into a single preferred URL. It also stops Googlebot wasting crawl time on duplicates instead of new reviews and updated offers.

Why start with the pages that already rank?

A slots or poker site's top pages, such as its main reviews, best sites lists and core guides, often drive much of its traffic and sign-ups. They are also the pages most often copied into weaker versions elsewhere on the same site. Strengthening them first gives the best return for the least effort.

Google is clear about what good affiliate content looks like. Its spam policies list "original product reviews, rigorous testing and ratings, navigation of products or categories, and product comparisons". For slots, that means real play-testing, screenshots, bonus round notes and honest comparisons. For poker, it means first-hand experience of the software, traffic and tournaments, and strategy written by people who actually play.

Updating a top page means adding substance, not changing the date. Google's guidance on creating helpful, reliable, people-first content, updated on 5 October, specifically asks whether sites are changing page dates to make content look fresh when it has not substantially changed. It also says large amounts of AI text published "without manual oversight or curation" represents little to no effort.

The same qualities help in AI search. Our guide to GEO and AEO for iGaming affiliates explains why original, well-sourced content is what gets cited in AI answers.

How do you find the duplicates?

• Check Search Console by query. Look for key queries, such as a slot name or "poker hand rankings", where several of your URLs receive impressions. That is the clearest sign of pages competing with each other.
• Group pages by template. Review slot reviews, bonus pages, room reviews and location pages as groups, not one by one, so repeated copy stands out.
• Map each page to one search intent. Pages that answer the same question are candidates to combine.
• Compare performance. In each group, the page with the most traffic, links and conversions is usually the one to keep.

Should you merge, redirect or remove?

• Merge and redirect when several pages cover the same topic. Move the useful, unique material into the strongest page, then permanently redirect the others to it. Google describes redirects as "a strong signal" that the target should become the main version.
• Use a canonical tag when near-duplicate pages need to stay live for players, such as a demo page that sits alongside a review. Google treats rel="canonical" as a strong signal too.
• Remove or exclude pages that add nothing and have no traffic or links worth keeping, such as expired bonus pages. For scaled, low-value content, Google's spam policies say to exclude it from Search.
• Rewrite pages that target a genuinely different intent but read the same as another page. Give each one a clear purpose and different content.

Then update internal links to point at the pages you keep, and take the merged URLs out of your sitemap.

How long does recovery take?

Google's page on spam updates and your site says affected sites should review its spam policies, and that changes "may help a site improve if our automated systems learn over a period of months" that the site complies. There is no quick fix.

With the rollout finished, 24 September to 8 October gives a fixed window to compare Search Console performance before, during and after the update. Search Engine Journal noted that real spam update effects tend to persist across consecutive days, so look for sustained changes in impressions and clicks, broken down by page group.
