Free SEO tools
These pages cover the SEO jobs you can finish from the text in front of you: a robots.txt file, a sitemap you already have the URLs for, the tags in a page head, and a DNS record.

About these tools
Crawl files write and check robots.txt, and build or check an XML sitemap. The sitemap tools use the URLs or the XML you paste. They do not crawl a website.
On-page tools draft a title and description, show a search-result length, preview a link card, count a keyword, list headings, and make a slug.
Link tools add UTM parameters, write JSON-LD, write hreflang links, and draft a redirect. The domain lookup asks Cloudflare’s public DNS for A, AAAA, NS and MX records and says so on the page.
Questions
Do these tools upload the HTML or the URLs I paste?
No. The generators and checkers run in the tab. The domain lookup is the exception: that query is sent to Cloudflare’s public DNS, not to this site.
Can I check domain authority, page authority or domain rating?
No. Those scores belong to other companies’ link indexes. This site does not invent a number and present it as a score.
Will the sitemap generator crawl my site?
No. Paste the URLs you want listed, one per line. A crawler would need to fetch other people’s sites, and these pages do not do that.
Do I need an account?
No. Every tool is free, with no sign-up.
