FAQ

Are SEO Hub tools free?

Yes. The initial SEO tools follow the same free, browser-first MetricLab model.

Does MetricLab submit pages to search engines?

No. The hub helps you inspect and prepare SEO signals. Publishing, crawling and indexing still happen through your site and search engine tools.

Do these SEO tools upload my page content?

No. All SEO tools in this hub run locally in your browser. Your page content and SEO data are never uploaded or sent to a server.
