Source Authority reveals which domains consistently shape monitored AI answers, turning citation reach, consensus, momentum, breadth, and context into a practical source strategy.

Qwairy maps when ChatGPT Shopping appears across 100,000+ monitored runs. A matched test found appearance rates ranging from 21.7% to 96.7%.

AI Revenue moves to GA with three-layer attribution and a self-serve GA4 setup, the Action Center leaves beta on every paid plan, and a new Pitch Audit lets agencies run one-shot GEO audits on prospects. Plus a refreshed Premium Models catalog and the MCP server now available from Starter.

A Qwairy research study on how AI answer engines frame the 2026 World Cup winner, where they agree, where answers become volatile, and what marketers can learn from AI perception mapping.

A complete, practitioner-level guide to Answer Engine Optimization: what AEO is, how answer engines like ChatGPT, Perplexity and Google AI Overviews select and cite content, the core levers, a step-by-step workflow, and how to measure it.
How Ornikar, France's online driving-school leader, built an operational GEO playbook to become a cited brand in AI answers across driving education and car insurance — with traffic and conversion gains following.

We measured how AI engines END their answers on the commercial questions brands compete on: how often the engine closes by offering to keep going ("If you want, I can narrow this down by budget, region, use case"). Measured across the major AI engines we monitor over a 90-day window.
Most analytics tools miss or misclassify AI referral traffic by default. This step-by-step guide shows you how to properly track visits from ChatGPT, Perplexity, Claude, Gemini, and other AI platforms in GA4, Plausible, and Matomo.

We tested the assumption behind Google's "AI optimization is just SEO" guidance: do the domains cited by Google AI match those cited by ChatGPT, Perplexity, Claude and the rest on the same question? They barely do - cross-engine overlap runs 4-19% (Jaccard), and the single top source matches 4-13% of the time. Measured across eight major AI surfaces on production brands, every prompt run repeatedly, over a 90-day window.

A practical three-way breakdown of SEO, answer engine optimization, and generative engine optimization: what each one means, where they overlap, and how to run them as a single AI visibility program.
