Frequently Asked Questions

What's the difference between the GEO Score and AI Visibility checkers?

The GEO Score Checker grades a single page on how ready it is to get cited by AI search engines, then points to what to improve. The AI Visibility Checker measures whether your domain is actually cited by ChatGPT, Perplexity, and Gemini right now. Start with GEO Score to fix a page; start with AI Visibility to see who's citing you today.

What does the Agent Readiness Checker do?

It checks whether AI agents can reach, discover, and parse your site: whether pages serve real content without JavaScript, whether robots.txt and llms.txt tell agents what is there, and whether your pages carry structured data and a Markdown version agents can read. You get every outcome plus plain-language guidance on what to fix, free.

Are these SEO tools free?

Yes. The GEO Score Checker is free, with your first result needing no signup. The AI Visibility Checker shows your ChatGPT result free; email unlocks the deeper Perplexity and Gemini read. For real-time scoring across your whole site, research, and the writing agent, Frase plans start at $39 per month with a 7-day free trial.

Which AI engines do the tools check?

The AI Visibility Checker probes ChatGPT for the free result, then Perplexity and Google Gemini after email capture, using AI-search-style phrases generated for your domain's industry. The GEO Score Checker grades a page against the signals these engines look for when they decide what to cite.

Do I need to sign up to use them?

No. The GEO Score Checker gives your first result with no signup. The AI Visibility Checker shows your ChatGPT result with no signup, and only the deeper multi-engine result asks for an email.

How does a free check connect to the full platform?

A check finds the gap. Frase closes it: the agent drafts the fix in your voice, publishes to your CMS or FraseCMS, and keeps watching with AI Visibility and Content Guard. The free tools are the top of that loop.

How accurate is a single check?

Each AI Visibility probe runs three AI-search-style phrases for your domain, so a free check is a snapshot: AI engines rewrite their answers constantly. That churn is the point. Fix a page, re-check, and watch the citation come back. Inside Frase, AI Visibility tracks that movement for you daily instead of one URL at a time.

Run the whole loop with Frase.

Research, the writing agent, real-time SEO and GEO scoring, AI Visibility, and Content Guard. One platform that keeps your content ranking and cited. See the AI SEO tool behind them.
