Free SEO tools — Open Pulse

6 free tools for getting a site found: structured data, head tags, the files crawlers and assistants read, and campaign URL tagging. No account.

What this page answers

What do these cost?

Nothing. No account, no card, and none of them store what you paste beyond the run that answers it.

Which one do I want?

Depends on the job. llms.txt and robots.txt are files to publish; the schema markup generator and the meta tag checker are about how a page reads to a crawler; the meta description generator writes copy; the UTM builder tags campaign links.

The six tools

  • [llms.txt Generator](/tools/llms-txt-generator) — Generates a spec-compliant llms.txt for any public site: the H1, the summary blockquote and a linked index of the pages worth reading, built from the site's own sitemap and title tags. Shows the existing file first if there already is one.
  • [Schema Markup Generator](/tools/schema-markup-generator) — Builds valid JSON-LD for twelve page types — Article, FAQ, Product, Organization, LocalBusiness, Person, Event, Recipe, Video, Breadcrumb, HowTo and JobPosting — with live validation against the fields Google actually requires for each.
  • [Meta Tag Checker](/tools/meta-tag-checker) — Fetches any public URL and grades its head tags the way a crawler reads them: title and description length, canonical, robots directives, Open Graph and Twitter cards, viewport, H1s and the structured data types present.
  • [AI Meta Description Generator](/tools/meta-description-generator) — Writes three meta descriptions from a topic, a set of keywords or a page URL, in your choice of tone, each inside the 155 characters a search result renders — editable in place, with a live preview of the result they produce.
  • [Robots.txt Generator](/tools/robots-txt-generator) — Reads the robots.txt you already serve, parses it the way Google's parser does, reports what it actually blocks, and generates a clean replacement with your sitemap and an explicit decision about AI crawlers.
  • [UTM Builder](/tools/utm-builder) — Composes UTM-tagged campaign URLs with presets for fourteen channels, forces the lowercase-and-hyphen convention GA4 needs to avoid splitting one channel into three, and tags a pasted list of URLs in one pass.
