Free SEO Tools — Meta Tags, Sitemaps, Minifiers & Checks

A practical toolkit for on-page SEO and site performance. Generate the meta, Open Graph and Twitter tags that control how your pages look in search and social; build a sitemap and robots.txt so crawlers find the right pages; minify HTML, CSS and JavaScript to load faster; and check keyword density and canonical tags.

Almost everything runs in your browser — no signup, no limits. The one exception is the Canonical URL Checker, which fetches the page you name from our server so it can follow redirects.

Why on-page SEO still matters

Search and social platforms read your tags, not your intentions. A missing meta description, a wrong canonical, or an unshareable link quietly costs traffic — and slow, unminified pages hurt both rankings and conversions. These tools fix the fundamentals in minutes, and because they're free and unlimited you can use them on every page you ship.

Frequently asked questions

Are these SEO tools free?

Yes, all of them, with no signup and no usage limits. Most run entirely in your browser.

Do I need to upload my site?

No. The generators and minifiers work on text you paste, in your browser. Only the Canonical URL Checker fetches a page — the URL you enter is sent to our server so it can follow redirects.

What's the difference between the meta, Open Graph and Twitter generators?

Meta tags control how your page appears in Google search results; Open Graph tags control the preview card on Facebook, LinkedIn and most chat apps; Twitter Card tags control the card on X. A well-optimised page usually has all three.

Does minifying really speed up my site?

Yes. Smaller HTML, CSS and JavaScript files download faster and are parsed sooner, improving load time and Core Web Vitals — which are a ranking factor.

What is a canonical tag and why check it?

A canonical tag tells search engines which URL is the 'main' version of a page, preventing duplicate-content problems. A wrong or missing canonical can split ranking signals, so it's worth verifying.
