Oct 1, 2025

This issue of the newsletter is sponsored by Olga Zarr's AI SEO Expert course whose presale just started and will end soon. ❌

AI SEO Expert = You

I missed writing to you, and I’m glad to be back in your inbox.

The last month and a half pulled me away—part health challenges, part deep dives into AI, SEO, and recording new lessons for SEO Audit Mastery and AI SEO Expert.

Now I’m back with a fresh digest of the most important AI + SEO news from the past month—so you can catch up in minutes instead of hours.

And one more thing: the presale for my upcoming AI SEO Expert course is ending soon. If you want in at the lowest price, now’s the time to grab your spot.

Happy reading!

September SEO & AI News Digest

A ton of news and I tried to pick the most important ones.

Google’s August 2025 Spam Update fully completes (27-day rollout).
Barry Schwartz from Search Engine Land reports the update started Aug 26 and finished Sept 22; impact was “hard and fast,” with volatility around Sept 9. The article explains this was a broad spam update with no new quirks called out. Search Engine Land

&num=100 removal crushes GSC metrics for most sites.
Danny Goodwin reports 87.7% of sites saw impression declines; 77.6% lost unique ranking terms in GSC after Google removed num=100. The article explains data may now be truer (less scraper inflation). Search Engine Land

Google removes 6 rich result types from Search Console & Rich Results Test.
Google confirms support is gone for Course Info, Claim Review, Estimated Salary, Learning Video, Special Announcement, Vehicle Listing. The post explains reporting stops now; API fields null by Oct 1 and API removal in Dec 2025. Google for Developers

Google introduces AI Mode visual exploration + conversational shopping.
Robby Stein & Lilian Rincon on The Keyword say you can ask visually, refine conversationally, and shop via Shopping Graph with hourly-refreshed listings. The article explains a “visual search fan-out” under the hood. blog.google

OpenAI adds in-chat shopping (Etsy now, Shopify next).
AP reports ChatGPT users can purchase via Stripe “Instant Checkout”; ranking for merchants factors in availability/price/quality. The piece explains OpenAI will not favor specific sellers. AP News

Google publishes AI Mode/Discover/Shopping product notes (September).
Google details Discover updates to help users follow creators/publishers, making it a stronger “jumping-off” point to the open web. blog.google
