About SEO Tools
14 SEO tools — check keyword density, preview Google snippets, validate robots.txt, and audit canonical tags locally. The sitemap crawler runs on our server (it must fetch the target site); everything else analyzes in your browser.

SEO FAQs
What is a good keyword density?
There is no magic number — the checker shows your term distribution so you can spot stuffing (same phrase every sentence) or dilution. Natural coverage across headings matters more than any percentage.
How long should meta titles and descriptions be?
Titles display fully up to ~60 characters; descriptions truncate around 155–160. The snippet preview shows exactly where Google cuts each one off.
What does the robots.txt validator check?
Syntax errors, contradictory Allow/Disallow rules, unreachable sitemap URLs, and whether a given user-agent path is actually crawlable — the three mistakes that accidentally deindex sites.
Why does the sitemap crawler run on a server?
It must fetch the target site, which a browser page can't do across origins at scale. Everything else on this hub — density, snippets, validators — analyzes locally.
