Snapshot for the week of August 3, 2026. Named = the engine wrote the brand into its answer. Cited = the engine linked the brand's own domain as a source, out of 25 answers.

Do the engines agree?

How often each engine named the brand, as a share of the questions it answered. Reading across a row shows whether the engines are describing the same market — the spread column is the gap between the engine that names the brand most and the one that names it least.

Named in 0%100% of answers

Values are the percentage of that engine's answers naming the brand. Each engine answered the same 5 questions here, so a cell moves in steps of 20 points. 2 brands are named in more than half of one engine's answers and never mentioned by another — the engines are not describing the same shortlist.

Named vs cited in SERP APIs

Two different kinds of visibility. The filled dot is how often engines wrote the brand into the answer; the hollow dot is how often they linked the brand's own domain as a source. The bar between them is the gap — and where the filled dot sits to the left, the brand is cited more often than it is recommended.

Gap column is percentage points, named minus cited. Widest this week: SerpApi, named in 92% of answers but cited in 24%. One brand is cited more often than named (negative gap) — engines use the site as a source without recommending it.

How this is measured

Every week cloro asks each engine the same 5 buyer-intent questions with US localization, then scores the answers with deterministic string and URL matching — no LLM judge, so the same answers always give the same score. The 0–100 AI Visibility Score weights mention rate (60%), citation rate (25%), and how early a brand is named (15%).

Frequently asked questions

How is the AI Visibility Score calculated?+

The score runs 0–100 and combines three signals: how often the brand is mentioned across engine answers (60%), how often an engine cites the brand's own domain as a source (25%), and how early the brand appears when it is named (15%). Detection is deterministic string and URL matching, not an LLM judgement, so the same answers always produce the same score.

Which AI engines are included?+

This snapshot covers ChatGPT, Perplexity, Gemini, Copilot, Google AI Mode. Every engine is asked the same 5 buyer-intent questions with US localization, giving 25 engine answers for this category.

How often does the leaderboard update?+

Weekly. A fresh sweep runs every Monday (UTC) and each page is stamped with the week it reflects. Rankings are deliberately not real-time — AI recommendations do not move hour to hour, and dated snapshots are easier to cite and compare.

What is the difference between a mention and a citation?+

A mention means the engine named the brand in its answer text. A citation means the engine linked the brand's own domain as a source. They are tracked separately because they are different kinds of visibility — a brand can be cited as a source without ever being recommended, and vice versa.

Can I reuse this data?+

Yes. Everything here is free to reuse with attribution under CC BY 4.0 — cite the category page and the week it covers.
