FAQ

Chrome extension

Is the Chrome extension free?

Yes. The on-page AEO/GEO audit and the AI Readability scan are free with no account. Paid plans are optional: Starter ($5 one-time) adds AI-generated meta and page copy, and Unlimited ($10/month) adds ongoing AI citation tracking.

What is an SEO AEO GEO checker?

It audits a page for classic SEO plus Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO): whether AI engines like ChatGPT, Claude and Perplexity can crawl, parse and cite the page. It checks structured data, llms.txt, AI-crawler access in robots.txt, content structure and meta tags. See the AEO Hub for the background.

Does it check llms.txt and robots.txt rules for AI crawlers?

Yes. It checks for llms.txt at the site root and reports robots.txt rules for GPTBot, ClaudeBot, PerplexityBot and GoogleOther. No llms.txt yet? Create one with the free llms.txt generator.

Can I audit competitor websites?

Yes. The audit runs on whatever page is open in Chrome, so you can check any public page, including competitors, without verifying ownership.

What data does the extension collect?

The on-page audit is local-first and scan history is stored in your browser. Create Content and citation checks use the SellOnLLM backend and only process the domain, prompts and page context you provide. See the extension privacy policy.

How is this different from a regular SEO extension?

Regular SEO extensions focus on Google rankings. This one also scores machine readability and citability for AI answer engines, compares what crawlers see without JavaScript to the rendered page, and can track whether AI engines actually cite your domain.
