What you can do here

Publishing a page well is a list of small checks: does the title fit in Google's results, will the link preview show the right image, are there broken links, is the favicon working, are the campaign links tagged consistently. These tools handle each of those checks in seconds, without an account or a subscription.

They run in your browser, so you can try them on drafts and staging pages that are not public yet. None of them replaces a full SEO audit, but each one catches a common, avoidable mistake.

  • On the page: title and meta description length, Open Graph and link preview, favicon checker.
  • Links: UTM builder, clean tracking parameters from URLs and check for broken links.
  • Technical files: robots.txt and sitemap.xml generator.
  • Assets and content: SVG optimiser and converter, Markdown tables, lorem ipsum and email signatures.

Frequently asked questions

Do these tools replace an SEO audit?
No. They check specific details, and are useful as quick checks while you write and publish.
Can I test pages that are not public yet?
The tools that take your own text or files work with anything. Those that fetch a URL need it to be reachable from the internet.
How long should a title tag be?
Around 50 to 60 characters, so it is not cut off in results. The checker measures both characters and pixel width.
What are UTM parameters?
Tags added to a link so that your analytics tool can tell which campaign, source and medium a visit came from.
Is my content stored?
No. Everything is processed in your browser.
