SEO tools for technical site setup

Technical SEO is mostly about getting a handful of small files and tags exactly right: the meta description and social preview tags in each page, a sitemap that lists the pages you want indexed, a robots.txt that doesn't accidentally block them, and structured data that describes the page accurately.

These generators produce valid, copy-paste-ready output from a simple form, and explain what each field does so you know why it matters. They run in your browser and do not crawl or submit anything on your behalf.

Good to know

After generating a sitemap or robots.txt, upload it to your site's root and submit the sitemap in Google Search Console and Bing Webmaster Tools yourself.
