What’s changing in AI search.
Answer engines are moving fast — new platforms, new research, new rules. This is the running log of what changed and what it means for getting your business cited, plus a few honest predictions about where it’s headed. For the timeless fundamentals, start with the AEO Canon.
The 2026 Model Wave: GPT-5.6, Claude Opus 4.8, Gemini 3.5 — What It Means for Getting Cited
2026 brought a flood of model releases from Anthropic, OpenAI, and Google, each splitting into flagship, balanced, and fast tiers. The AEO takeaway — don't chase model quirks. The retrieval and citation layer they sit on is stable, so being the most trusted source is the durable play.
Prediction: The First Real 'Agentic' Holiday Shopping Season Is Coming
My bet Q4 2026 is the first holiday season where AI shopping assistants meaningfully sway purchases. With ChatGPT fielding ~50M shopping queries a day and "discover in AI, buy on site" now normal, the retailers who win are the ones AI can read and recommend.
Cloudflare Wants AI to Pay for Content: 'Pay Per Crawl' Becomes 'Pay Per Answer'
Cloudflare's Pay Per Crawl marketplace is evolving toward Pay Per Answer, charging AI companies when publisher content appears in an answer. For most businesses the real risk is accidentally blocking the AI crawlers you want, so audit your robots and CDN settings now.
5 Predictions for AI Search in the Rest of 2026
My bet for H2 2026 answer engines get faster and pickier, Cloudflare's crawler blocking reshapes who gets cited, and "discover in AI, buy on site" becomes the default commerce path. Here's what to do about each.
Prediction: 'Pay Per Answer' Reshapes the Open Web by 2028
My bet by 2028, AI answers routinely pay or license the sources they use — and citations flow to trusted, licensable, well-structured publishers. Cloudflare's Pay Per Crawl and Perplexity's publisher revenue share are the early proof. Here's how to prepare.
What AEO Looks Like in 2027: Our Predictions
By 2027 I expect citation share to be a board-level metric, your brand entity to be the real moat, and agents — not just people — to be the audience you optimize for. Here's how practice, budgets, and measurement shift.
Less Than a Third of Google Searches Now Send a Click
SparkToro says fewer than one in three Google searches still sends a click, and Similarweb puts the zero-click rate near 69%. For businesses, the click is disappearing — the win is being the cited source inside the answer.
The Answer-First Web: Where AI Search Is Headed by 2030
My longer-horizon bet by 2030 search becomes an agentic, conversational, multimodal layer, brands are recognized as entities rather than pages, and the open web is funded partly by licensing and pay-per-answer. Grounded, and humble about what's uncertain.
Prediction: By 2027, 'Near Me' Belongs to Whoever AI Trusts
My bet by 2027, "best plumber near me" and "good dinner in town" get answered by AI naming one or two businesses — not a list. The local winners will be those with a clean entity, consistent citations, and real reviews. Everyone else goes invisible.
Regulators Circle AI Search: Google Antitrust, EU Probes, and a German Court Ruling
The rules of AI search are being written in courtrooms — a US Google antitrust appeal, EU Digital Markets Act probes, a German ruling on false AI Overview claims, and a publisher lawsuit. Expect more pressure for transparency and source attribution.
Perplexity's Comet Browser Goes Free Worldwide — and Pays Publishers
Perplexity made its agentic Comet browser free worldwide and expanded it across every major platform, while a $5/mo Comet Plus tier routes ~80% of revenue to publishers. For AEO, the browser itself is becoming the interface — and being the source Comet cites is the game.
Google Put Your Gmail Inside Search: What 'Personal Intelligence' Means for AEO
At I/O 2026 Google expanded Personal Intelligence in AI Mode to nearly 200 countries and 98 languages, letting users connect Gmail and Google Photos with no subscription. As answers get personalized, generic ranking matters less and being a trusted, clearly-defined entity matters more.
Search Live: Camera-and-Voice AI Search Changes What 'Content' Means
At I/O 2026 Google unveiled its biggest search box redesign in 25+ years — accepting text, images, files, videos, or Chrome tabs — plus "Search Live" conversational multimodal search. Being citable now means structured, described, transcribed content, not just prose.
Google AI Mode Hits 1 Billion Users — and Starts Replacing AI Overviews
At I/O 2026 Google said AI Mode passed 1 billion monthly users and began routing people from AI Overviews into a fuller conversational search. For businesses, it means fewer blue links and a higher premium on being the source AI names.
AEO Tooling Crosses $200M in Funding as Citation Tracking Goes Mainstream
The AEO/GEO tooling category has drawn $200M+ in disclosed funding as of early 2026, with Profound, Bluefish, Evertune, and Scrunch leading. Measurement is maturing, but tools only measure citations — fundamentals still earn them.
llms.txt One Year On: ~10% Adoption, and AI Crawlers Still Ignore It
An SE Ranking study of 300,000 domains found about 10% of sites now publish llms.txt, but AI search crawlers overwhelmingly skip it and read HTML directly. It is not a citation lever — its real value is in the agentic developer layer.
ChatGPT Killed Instant Checkout — the New Rule Is 'Discover in AI, Buy on Your Site'
OpenAI discontinued Instant Checkout in March 2026 after fewer than 15 Shopify merchants went live, pivoting to a discovery-first model. The durable takeaway for ecommerce is to be the recommended product in the AI answer, then convert on your own site.
Two Protocols Will Decide How AI Sells Your Products: ACP vs UCP
Agentic commerce is standardizing around competing protocols — Stripe and OpenAI's ACP, and Google's coalition-backed UCP announced in January 2026. Whichever wins, structured, machine-readable product data is the entry ticket to being recommended by shopping agents.
