SERP Sitrep: H1 July recap​

1. Fake DMCA Takedowns in Google Search
Google's feature to request takedown of content that infringes copyright was heavily abused and turned into a negative SEO nightmare. https://www.blackhatworld.com/seo/fraudulent-dmca-takedowns-in-google-search-a-negative-seo-nightmare.1829348/ are weaponised by many people to get rid of competition.

2. The AI Referral Shakeup: ChatGPT Takes 92%, Claude Beats Perplexity
A massive data study https://previsible.com/seo-strategy/ai-traffic-report-july-2026/ (analyzing 6.77 million LLM sessions across 166 sites) revealed that ChatGPT now commands 92.4% of all AI referral traffic. Claude quietly overtook Perplexity in AI referral traffic, growing 64x over the past year, while Perplexity referrals dropped 61% from their peak and Microsoft Copilot collapsed by 96%.

ChatGPT sends 28.8% of its referral clicks to a domain's internal site search page rather than the specific deep link answering the query. Make sure your internal search results page is optimized for conversions, loads quickly, and doesn't return "0 results found" for common AI-queried terms.

3. AI Performance Insights in Google Merchant Center
Google officially rolled out https://support.google.com/merchants/answer/17200695?hl=en, allowing e-commerce owners to see impressions and clicks specifically from AI Mode and AI Overviews. E-commerce affiliates and drop-shippers can finally see if AI Overviews are stealing or driving product clicks.

4. Bing AI Performance Reports
Bing Webmaster Tools https://www.seroundtable.com/bing-webmaster-tools-ai-reports-backfill-41606.html into its new AI Performance Reports, giving SEOs clearer attribution on where Copilot and Bing chat pull citations.

5. Google Search Console Shows Performance Reports for Social Media Properties
GSC added a new feature called https://www.blackhatworld.com/seo/google-search-console-shows-content-search-performance-for-instagram-tiktok-x-and-youtube.1830976/ that allows users to add their Instagram, Tiktok, X, and YouTube properties and track their impressions & clicks on Google search.

6. Cloudflare Introduced New Rule to Block Googlebot from Scraping Content for AI Training
Cloudflare introduced https://www.searchenginejournal.com/cloudflares-ai-crawler-rules-can-block-googlebot/581385/ that now allow webmasters to block Googlebot specifically from scraping content for AI training, while still allowing indexing.

7. Google Ignores Cloudflare’s New Directive
Google's John Mueller https://www.reddit.com/r/TechSEO/comments/1uo1rpb/testing_whether_contentsignal_headers_and_llmstxt/ that Google ignores Cloudflare’s new "Content Signals" robots.txt directive. If you want to control Google's AI crawling, you must use standard Google-specific user-agent blocks. If you are running PBNs and using Cloudflare's one-click "block AI" switches, Google is ignoring your signals unless you manually configure your 'robots.txt' for 'Google-Extended'.

8. OpenAI User-Agent Can Now Update Dynamically to Bypass Blocklists
OpenAI updated its crawler protocols, noting its user-agent strings can now https://x.com/rustybrick/status/2076992982092235085 to bypass legacy static IP/user-agent blocklists. OpenAI scraping bots are getting harder to block with static rules. If you are scraping or protecting content from AI bots, you need dynamic behavioral bot protection, not just user-agent filtering.

9. Google Kills Cached AMP Pages
Google Search https://developers.google.com/search/updates#updating-amp-documentation serving Google-hosted/cached AMP pages to users. All mobile searchers clicking an AMP result are now sent directly to the publisher's domain-hosted AMP URL.

10. ChatGPT Ads Manager Rapid Expansion
Throughout the second week of July, OpenAI https://www.seroundtable.com/chatgpt-ads-attributed-sales-value-and-sales-roas-41674.html to ChatGPT Ads, introducing custom audience lists, attributed sales value, ROAS tracking, and suggested ad drafts. Google Ads countered by expanding mandatory AI ad disclosures across Search, YouTube, and Discover.

Solid recap! Points 2 and 7 are especially eye-opening.

The stat about ChatGPT sending nearly 29% of referral traffic to internal site search pages instead of deep URLs is huge—definitely an overlooked area that most webmasters never think to optimize.

Also, good callout on the Cloudflare AI blocking situation. Relying on automated one-click toggles without verifying standard Google-Extended rules in robots.txt is going to catch a lot of people off guard. Appreciate the detailed breakdown!

SEO News & Updates​

1. Google Splits "Site Reputation Abuse" Enforcement for Europe
Google quietly adjusted how it enforces its Site Reputation Abuse policy inside the European Economic Area (EEA) due to local regulatory pressures (DMA compliance). Outside Europe, sites hit with site reputation abuse often receive a site-wide or directory-level manual action. Inside the EEA, Google confirmed it is decoupling the subfolder's ranking authority so it ranks strictly on its own merits rather than sharing the host domain's reputation.

2. Content API for Shopping Sunsets: The HTTP 410 Wave
Following the August 18 deprecation, Google officially began returning HTTP 410 "Gone" error responses starting September 1 for unapproved legacy Content API for Shopping calls. All merchants must be fully migrated to the new Merchant API to keep live product feeds synced.

3. CloudFlare Now Defaults To Allowing AI Scraping Of Your Sites
Cloudflare settings now allow crawlers that crawl to train AI models by default. Although their blog post recommends disallowing crawlers that intend to train AI models, they left the setting turned on.

4. Google Documentation: Regional Search Experience Disclosures
In September, Google updated its official Search documentation to formally detail "Regional differences in Search experience," codifying how SERP layouts, AI Overviews, and rich results differ between the US, the EU (DMA zone), and global regions.
 
SEO News & Updates​

1. The Mid-September Rollercoaster: Cliff Drops & Sudden Reversals
Search trackers and SEO analysts (including Glenn Gabe and Barry Schwartz) reported extreme ranking turbulence starting around September 4, followed by fresh spikes on September 15–16.

The anomaly: Around September 13, a significant number of domains that "fell off a cliff" on September 4 spontaneously rebounded and recovered their positions, only for another wave of tremors to hit on September 15.
Google's official Search Status Dashboard has not confirmed an update, indicating either testing of unannounced core weights or extended downstream data syncs following the August Spam sweep. The automated reversal pattern confirms Google's classifiers are aggressively testing weight thresholds in live SERPs.

2. Page Experience Docs Add CrUX Ad Metrics (Watch Your Ad Density)
On September 22, Google officially updated its Page Experience SEO documentation to add Chrome User Experience Report (CrUX) advertising metrics. Specifically, Google is now tracking Ad Count, Ad Density (percentage of the viewport occupied by ads), and Ad Weight (CPU execution time and network data consumed by ad scripts).

3. E-Commerce Shift: Google Rolls Out "Native Checkout" in AI Mode & Gemini
On September 22, Google began auto-enabling Native Checkout inside AI Mode and the Gemini app for eligible Merchant Center and Shopify sellers. Consumers can now click "Buy" directly inside the generative AI chat interface to purchase items without ever landing on the merchant's actual website.

4. The "NotebookLM / Gemini" Parasite Spillover
Between September 20 and 22, SEOs noticed public Google NotebookLM and shared Gemini workspace URLs indexing rapidly and ranking for commercial search queries, functioning almost like a high-authority parasite platform.

5. Legal & Platform Pressure: UK CMA Eyes Android/Chrome Defaults
On September 23, the UK Competition and Markets Authority (CMA) proposed new rules forcing Google to make it easier for Android and Chrome users to switch to alternative search engines and standalone AI search platforms.
 
SEO News & Updates​

1. Google's September 2026 Spam Update is Actively Rolling Out
On September 24 at 09:15 PDT, Google officially released the September 2026 Spam Update across all languages and regions globally. The Critical Difference: Unlike the March, June, and August spam updates, which each finished in roughly 2 to 3 days, Google announced this rollout could take up to two weeks to complete. Trackers and forum chatter recorded massive weekend volatility peaking on September 25–27 as the initial wave hit.

2. GSC Reporting Overhaul: "Web" Traffic Split into Text vs. Multimodal
On September 24, Google introduced a structural change to Google Search Console Performance Reports: "Web" search type is now split into two sub-options: Web (text) and Multimodal. "Multimodal" isolates searches where visual inputs (like Google Lens, Circle to Search, or image-driven prompt queries) were part of the search interaction. If you are running programmatic product galleries, Pinterest-style arbitrage, or visual guides, you can now isolate your Multimodal traffic to reverse-engineer how visual queries are triggering impressions versus standard keyword searches.

3. Massive Google Merchant Center Policy & API Rewrite
Late last week, Google pushed major updates across multiple core Merchant Center policy documents, including Dangerous products, Counterfeit products, Products that enable dishonest behavior, and Editorial requirements.
Simultaneously, Google completely rewritten and expanded its documentation for the new Google Merchant Center API (following the legacy Content API shutdown).

4. Google Tests Replacing "Show More" with "Loading..." on AI Overviews
Over the weekend, Google was spotted testing a dynamic "Loading..." indicator under AI Overviews instead of the traditional "Show more" accordion button, dynamically fetching live follow-up sources as the user scrolls.
Google is working to reduce friction in AI Mode and AI Overviews to make conversational search feel infinite. The deeper Google pushes dynamic streaming into the AI Overview box, the further down the "10 blue links" are pushed below the fold. Prioritizing entity citations inside the LLM answer is no longer optional.
