GEO Checker vs Semrush
Semrush is a full SEO suite. GEO Checker is a narrow, free tool for one job: verifying that AI crawlers can access and understand a page.
| GEO Checker | Semrush | |
|---|---|---|
| Main purpose | Technical AI-crawler accessibility check for a single URL | All-in-one SEO platform (keywords, backlinks, site audit, rank tracking and more) |
| AI-search features | robots.txt per AI bot, live UA access test vs browser, llms.txt, schema gaps | Semrush offers AI-search / AI visibility features as part of its platform; see Semrush for current scope |
| Live WAF / Cloudflare test per AI user-agent | Yes | Check vendor documentation |
| Copy-paste JSON-LD fix code | Yes | Check vendor documentation |
| Price model | Free single check; paid plans planned | Paid subscription (see vendor pricing page) |
| Sign-up required | No | See vendor website for current account requirements |
When to choose which
Use Semrush if you need keyword research, backlink data, rank tracking and broad site audits — GEO Checker does none of that.
Use GEO Checker if you just need a fast, free answer to “can AI crawlers reach and parse this page?” and want fix code. Many teams use both.
