What These Free SEO Tools Do
Our free SEO tools do the jobs that decide whether a page gets found. First, the SEO checker reads your live page and lists what to fix, from the title to the links. Then the meta tag, schema and Open Graph tools write the code for each fix.
Next come the files a crawler reads first. So the robots.txt generator and validator, the XML sitemap generator, and the hreflang and canonical tag tools sit here too. Each one builds valid code from a short form, so you do not have to remember the rules.
Links are the other half of SEO. Therefore this page also holds tools that build a clean address, follow a redirect chain to its end, and pull every link out of a page. Most of them run in your browser, and the few that read a live page fetch only the address you give them.

Questions about these SEO tools
Are these SEO tools really free?
Yes. These free SEO tools have no price, no trial and no sign-up. In addition, most of them have no daily limit.
Which SEO tool should I start with?
Start with the SEO checker. It reads your page, scores it, and links each problem to the tool that fixes it.
Do the tools store my pages or keywords?
No. The tools that work on text run in your browser. The ones that read a live page keep nothing after the check.
Can these tools replace a paid SEO suite?
For on-page work, often yes. However, they do not track rankings or backlinks over time, and paid suites do.
