🔎 Free SEO & Metadata Tools
Everything here writes or checks the markup search engines actually read — the title Google shows, the card that appears when someone shares your link, the structured data that earns rich results. The tools run in your browser, so nothing you paste is sent anywhere - except the PageSpeed checker, which asks Google to test the address you enter.

How to get the most out of these
The tools here share one idea: write the markup by hand, understand it, then paste it. Generators are quicker than remembering syntax, but the fields you fill in still decide everything - a generated title tag with a weak title is weak markup, delivered efficiently. Use the SERP preview to judge the words, then the tag generators to package them.
A workflow that covers a page in ten minutes: draft title and description in the SERP preview, generate the head tags, add Open Graph for sharing, and - if the page carries an article, FAQ, or video - the matching JSON-LD from the schema generators. Finish in Google's Rich Results Test, which has the final say this site's tools cannot have.
One exception to the everything-runs-locally rule in this category: the video schema generator sends the YouTube URL you paste to a lookup function, because the video's metadata lives on YouTube's servers. Its page says the same thing. Every other tool here works with the network cable pulled out.
