AI Visibility — GEO & AEO
4 min read · Updated 19 Jul 2026
More and more buyers ask ChatGPT and Perplexity instead of Google. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) are about being the site the AI names and cites. RankAgent checks both the technical readiness and the actual outcome.
LiveGEO/AEO checks: all crawls · Scoreboard: Starter and up
The AI-visibility scoreboard
LiveStarter and up · live Perplexity is an add-on
The Growth → Search & AI panel runs three separate methods and shows them together:
- AI Brand Knowledge — asks a model, with no web access, what it already knows about your brand from training. Do the big models recognise you, your audience and your services?
- AI Discovery Index — builds realistic customer questions and asks them live (via Perplexity's web search when configured), then checks whether your site was cited or your brand named in the answer. The questions are grounded in the real queries your site already gets impressions for in Google Search Console — not just self-chosen keywords — so the test reflects actual demand. When you are cited, it shows your citation rank (were you the top source, or #7?), because a low-ranked citation gets quoted far less.
- LLM Readability — scores your crawl's GEO signals: schema present, AI crawlers confirmed allowed, llms.txt present. Graded A–F.

Honest measurement
A single "AI visibility %" is noisy, and different engines cite different sources. RankAgent keeps the three signals distinct and shows the actual cited sources and prompts behind the number — not one blended figure with nothing under it. When a live-search key isn't set, the discovery check falls back to a simulation and says so; it never fabricates a citation.
GEO: can the AI even reach you?
LiveAll crawls — including the free scorecard
Several crawl checks decide whether AI engines can retrieve your pages at all:
- Indexable — the page isn't hidden with a
noindexmeta tag orX-Robots-Tagheader. This is the single most common "why am I invisible" cause. - AI-crawler access — your robots.txt doesn't block GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended or CCBot.
- JS-shell detection — flags pages whose content only appears after JavaScript runs, which AI crawlers often can't retrieve.
- llms.txt — present and genuine (not an HTML soft-404).
On llms.txt
RankAgent checks for llms.txt and can generate one, but it's treated as optional hygiene, not a ranking win — there's no proven ROI, and Google's own guidance downplays it. We won't inflate your score for having it. Crawlability and content quality matter far more.

AEO: is your content quotable?
LiveAll crawls
On pages with real content, RankAgent checks the structure AI answers tend to pull from:
- Question headings — at least one H2/H3 phrased as a question (the People-Also-Ask / AI-Overview pattern).
- Answer blocks — a direct 1–3 sentence answer right under each question heading, which is the exact passage answer engines quote.
- Original data — concrete numbers, percentages or cited stats, one of the strongest levers for getting quoted.
- Comparison structure — on "best / vs / alternative" pages, a clear side-by-side (table or "X vs Y") that AI recommendation prompts pull from.
- Author signals — a byline or author markup (E-E-A-T).
- Freshness — a visible or marked-up published/updated date.
- Schema type awareness — FAQ schema on Q&A pages, breadcrumb schema on deep pages, so your facts are machine-readable.
Free GEO tools
Three of the free tools go deeper on specific GEO questions and work without a login: the Citation Finder (which exact sources an AI cites for a query), the AI Share-of-Voice Matrix (you vs. rivals across engines), and the Entity Gap Analyzer (topics a competitor covers that you don't). Learn more on the GEO overview page.
Plan
The in-product AI-visibility scoreboard and GEO/AEO checks are on Starter and up. Live Perplexity citations are an optional add-on (PERPLEXITY_API_KEY); without it the check runs on the built-in simulation.
