ChatGPT cut its Reddit citations by more than half.

For you: Reddit threads are no longer a dependable route into ChatGPT, so effort goes to the sources it still trusts: your own pages, guides, listings, and press.

Cloudflare blocks some AI bots by default on new domains.

For you: on pages that show ads, AI agents can be blocked without anyone deciding to, so check your settings.

Myth ✕

llms.txt files go largely unread.

For you: almost no AI crawler requests the file, so it never comes before content, access or authority.

Google retired FAQ rich results.

For you: keep FAQ answers on the page for guests and AI, but stop expecting the search snippet.

Myth ✕

Schema markup does not win AI citations.

For you: a controlled test of 1,885 pages found no major lift, so we use schema for clarity and put the effort into visible content.

What we have stopped recommending, and why

TacticWhat changedWhat we do instead
llms.txt as a visibility lever97% of files receive no requests (Ahrefs, Jun 2026)We no longer include it; the time goes on content, access and sources
Schema as a citation tacticNo measurable citation lift in controlled testingSchema for clarity; complete, visible facts on the page
FAQ markup for search snippetsGoogle withdrew FAQ rich results in May 2026Visible answers to real guest questions
Reddit seeding for ChatGPTChatGPT's Reddit citations fell sharply in AugustEarned coverage and accurate listings; genuine, disclosed answers on Reddit kept for Perplexity
Content chunking or rewriting pages "for AI"No evidence it helps; risks thin pagesPages written for guests, with the facts stated plainly

AI search changes faster than most review cycles. We re-test our own advice every month.

How do you rank in AI Overviews now?

Google says no special markup or files are needed. AI Overviews draw on pages that already rank, answer the question in their opening lines and are easy to read. Strong SEO plus answer-first content remains the route in.
