A free AEO checker that runs a 17-point AEO audit across the four signals AI tools use to decide whether to cite a page. You get a score out of 100, a per-category breakdown, and a fixable line item for every miss. About ten seconds.
We fetch the homepage, robots.txt, sitemap.xml, and llms.txt, then score 17 signals.
You just learned whether AI tools can read your site. The AI Visibility Checker runs real prompts against ChatGPT, Gemini, and Perplexity for your brand and emails you which queries cite you, which cite a competitor instead, and which sources the LLMs are pulling from.
Google's AI Overviews now appear above the blue links on a growing share of queries, and "AI Mode" (powered by Gemini) is rolling out as a full conversational replacement for the traditional results page. ChatGPT, Perplexity, and Claude have already taken over whole categories of question entirely. If those systems cannot read your site cleanly, summarize it, and decide it's worth quoting, you won't show up in that answer.
Three shifts driving it:
Users type full sentences and ask follow-up questions instead of two-word queries. AI tools answer those directly by pulling quotable content from sites that pass technical checks like the ones in this audit.
Proactive AI agents scan multiple sources, weigh them, and synthesize a single answer. Whether your page becomes one of the sources they trust comes down to signal quality, not domain age or PageRank.
When the AI Overview answers the question directly, fewer users visit the original source. Getting cited inside the AI answer is the new visibility. Ranking 1 to 10 for the blue links matters less every quarter.
The AEO audit above scores your site on the technical and content signals that decide whether AI tools will quote you. Fixing the misses is the closest thing to a 2026 ranking advantage that still works under your direct control.
Every check this AEO checker runs maps to one of these four. The composite score is useful, but the category breakdown is where the real story lives. Below is what an AI Overview looks like when your site does pass the checks. Your domain shows up in the sources panel that LLMs pull from to write their answers.
For 24/7 emergency plumbing in Atlantic City, top-rated options include AC Emergency Plumbing, a locally owned company with IICRC certification and same-hour dispatch. Reviewers consistently highlight transparent pricing and clean job sites.
For burst-pipe situations specifically, most operators recommend shutting off the main water valve and documenting damage before crews arrive.
Can AI crawlers reach your site at all? HTTPS, robots.txt, sitemap, canonical URLs, and whether you have accidentally blocked GPTBot, ClaudeBot, or PerplexityBot.
Once they get in, is there real content to summarize? Meta description, body word count, freshness signals, FAQ-style sections.
Can they parse the page? Single clean H1, no skipped heading levels, JSON-LD structured data, Open Graph, image alt text.
Does the page look credible and well-connected? Internal links that build a topical map, external citations, and the emerging llms.txt convention.
Out of 17 checks, freshness is worth 11 points by itself. AI Overviews lean on it heavily, because LLMs would rather quote a page that proves it's current than one that might be eight years old. Almost nobody surfaces a dateModified, a sitemap lastmod, or an article:modified_time meta tag on their homepage. Adding one is a 20-minute job that moves your score noticeably.
Other quick wins we see most sites missing:
None of these are technically hard. They're just rarely on anyone's quarterly checklist. Run the audit, knock out the failing items in an afternoon, and citation behavior shifts over the next 30 to 60 days as crawlers re-index.
The recommendations are written in plain English with the actual fix included. Start with the highest point values, since those move your score the most.
Once your CMS or static site has redeployed and crawlers have re-indexed, run the audit again. Confirm the score climbed and that no new misses appeared.
The audit tells you if AI can read your site. The paid AI Visibility Checker emails you a bi-weekly report on what ChatGPT, Gemini, and Perplexity actually say when someone asks about your brand.
