Which Free Chrome Extensions Help With GEO Audits?
Four free extensions cover most of a page-level GEO audit. Adobe's AI Content Visibility Checker shows what share of a page AI agents can read. Robots Exclusion Checker flags robots.txt rules, noindex tags and blocks on AI bots. View Rendered Source shows what JavaScript adds after the page loads, which many AI fetchers never see. Detailed SEO Extension shows headings, schema, canonicals and hreflang in one click. None of them sees firewall or CDN blocks, Bing indexing, or whether AI answers actually cite you. Use them for fast checks on key pages, then confirm the important findings with server logs and real prompts.
Which extensions are worth installing?
As listed on the Chrome Web Store and the developers' sites:
| Extension | What it checks | Why it matters for GEO |
|---|---|---|
| AI Content Visibility Checker (Adobe) | A Citation Readability Score: the percentage of a page AI agents can access, and a side-by-side human view | Shows content hidden from AI fetchers, usually by JavaScript |
| Robots Exclusion Checker (Sam Gipson) | robots.txt rules, meta robots, X-Robots-Tag, canonical, nofollow; whether robots.txt blocks 14 AI bots from OpenAI, Anthropic, Google, Perplexity, Meta and Apple | Finds pages or bots blocked by directives |
| View Rendered Source | Raw HTML, rendered DOM, and the line-by-line difference | Shows exactly what JavaScript adds or changes |
| Detailed SEO Extension | Headings, meta tags, schema markup, canonical, hreflang, links, X-Robots headers, sitemap link | Quick check of structure and structured data |
All four are free. Check each extension's permissions before installing, since page-reading extensions can see the sites you visit.
Adobe AI Content Visibility Checker: can AI read the page?
Adobe's extension compares what an AI agent fetching the page for citation can read with what a person sees, and gives a Citation Readability Score as a percentage. A low score usually means key content, such as prices, specifications, reviews or tabbed text, loads through JavaScript after the initial HTML. Adobe built it as a single-page diagnostic for its enterprise product, but it works on any site. It is the fastest way to find template-level problems: check one page of each template, not every page.
Robots Exclusion Checker: are AI bots blocked?
This long-standing SEO extension now includes an AI bots check. It monitors 14 bots from six companies, covering training, search indexing and real-time browsing, and shows an "AI" label when robots.txt excludes any of them. That distinction matters, because blocking a training crawler such as GPTBot is a different decision from blocking a search crawler such as OAI-SearchBot, or a user-triggered fetcher such as ChatGPT-User. The extension also shows the exact robots.txt rule affecting the current URL, plus meta robots and X-Robots-Tag directives.
View Rendered Source: what does JavaScript change?
View Rendered Source shows three panes: the raw HTML the server sent, the rendered page after JavaScript ran, and the differences highlighted line by line. Many AI fetchers read the raw HTML only. If your product details, FAQs or main text appear only in the rendered pane, those fetchers are likely to miss them. It confirms what Adobe's score suggests, and shows exactly which elements to move into the server response.
Detailed SEO Extension: is the structure clear?
Detailed shows a page's title, description, headings, canonical, robots directives, schema markup and hreflang at a click. For GEO, the useful checks are:
- Headings that follow the questions people ask, in a sensible order.
- Schema present in the source, and matching what the page says.
- Canonical and hreflang pointing to the right versions, so AI systems cite the page you intend.
What can Chrome do without any extension?
Chrome's built-in developer tools cover two useful checks for free:
- Turn off JavaScript from the DevTools command menu and reload the page. What remains is roughly what a fetcher that does not run scripts receives.
- Change the user agent under network conditions to an AI crawler's published user-agent string, and reload. Some sites serve different content, or a block page, to bots. This shows what your server sends, although it will not reproduce firewall rules that also check IP addresses.
These take a minute each and confirm what the extensions suggest.
What do extensions miss?
Browser extensions see the page as your browser does. Several important GEO problems are invisible to them:
- Firewall and CDN blocks. Robots.txt may allow a bot while your CDN or firewall blocks or challenges it. Check server or CDN logs for AI bot requests and their status codes, or request a page with a bot's user agent from the command line.
- Bing indexing. Bing feeds Copilot and is one of the sources studies link to ChatGPT search. Check key pages in Bing Webmaster Tools.
- Whether AI cites you. An extension cannot tell you what assistants say. Run your buyer questions in ChatGPT, Perplexity and Google's AI features, or use a tracker.
- Site-wide patterns. Extensions check one page at a time. For hundreds of pages, a crawler with JavaScript rendering and custom user agents is faster.
- Off-site sources. Reviews, lists and directories that AI answers cite sit outside your site.
A free, fuller audit method is set out in how to get a free GEO or AEO visibility audit for a website, and a URL-based approach in how to audit your website for AI visibility gaps using its URL.
What about "AI readiness score" extensions?
Many newer extensions give a page an AI readiness or GEO score out of 100. They can be handy reminders, but their scores are heuristics built by each vendor, and a high score does not mean AI answers will cite the page. Use them to spot missing basics, such as absent schema or thin headings, not as a measure of visibility. Prefer checks you can verify yourself: what the raw HTML contains, what robots.txt says, and what assistants actually answer.
How should you run a 30-minute page audit?
- Pick five pages: your homepage, a top product or service page, a pricing page, a guide, and a comparison page.
- Run Adobe's checker on each and note any score well below 100%.
- Open View Rendered Source on low scorers and list what appears only after rendering.
- Check Robots Exclusion Checker for blocked URLs and the AI label.
- Review Detailed for headings, schema and canonical on each page.
- Test two buyer questions per page in ChatGPT and Perplexity, and note whether the page, or your brand, appears.
- Confirm access in logs for the pages that matter most, looking for AI bot requests and errors.
What might this look like in practice?
Consider an illustrative furniture shop, Kestumb Furniture. Adobe's checker scored its sofa pages at 38%. View Rendered Source showed that dimensions, fabric details and reviews were loaded by a script after the page rendered. Robots Exclusion Checker showed no AI bots blocked in robots.txt, but the shop's CDN logs showed ChatGPT-User requests receiving challenge pages. The developer moved product details into the server-rendered template and allowed OpenAI's published agents through the CDN. A recheck scored the sofa pages at 94%.
What do people ask about GEO Chrome extensions?
Are these extensions free?
Yes. All four listed here are free on the Chrome Web Store.
Can an extension tell me if ChatGPT cites my site?
No. Extensions check pages and directives. To see citations, run the questions yourself or use a tracker.
Does allowing bots in robots.txt guarantee access?
No. Firewalls and CDNs can still block or challenge AI bots. Check your logs.
Which extension checks JavaScript problems?
Adobe's AI Content Visibility Checker gives a score, and View Rendered Source shows exactly what changes.
