Frequently Asked Questions
Is Foglift a replacement for Screaming Frog?
They serve different purposes. Screaming Frog excels at deep site crawls (thousands of URLs, custom extraction). Foglift is better for quick, instant analysis with GEO readiness checks that Screaming Frog doesn't offer. Many users use both: Foglift for quick checks and AI search optimization, Screaming Frog for deep technical audits.
Can Foglift crawl an entire website like Screaming Frog?
Currently Foglift analyzes one page at a time (or via API for automation). Screaming Frog can crawl thousands of URLs at once. However, Foglift's API and MCP server let you automate multi-page scanning through scripts or CI/CD pipelines.
Does Screaming Frog check for AI search optimization?
No. Screaming Frog doesn't analyze GEO (Generative Engine Optimization) factors like AI crawler access, structured data depth for AI, FAQ section detection, or citation-friendly formatting. Foglift is currently the only free tool that checks both SEO and GEO.
Which tool should a small business use?
For small businesses, Foglift is the better starting point. It's free, instant, requires no download, and explains issues in plain English. Screaming Frog is more suited for SEO professionals who need deep crawl data and don't mind a learning curve.
Can I use both tools together?
Absolutely. A common workflow is: use Foglift for quick GEO + SEO checks and monitoring, then use Screaming Frog for deep technical crawls when you need to audit hundreds of pages at once. They complement each other well.
