Frequently asked questions

Are these SEO tools free to use?

The 35 browser utilities included here are free to use. External platforms may require an account, have usage limits or offer paid plans; check each provider's current terms.

Do these tools crawl my website automatically?

No. Browser utilities process data you paste or enter. They do not fetch pages or crawl websites. Use a specialist platform for live crawling, performance testing, backlink data or index reporting.

Can generated schema guarantee rich results?

No. Valid structured data does not guarantee a rich result. Review Google's current requirements and test your markup with an appropriate validator before publishing.
