mttr and Semrush

Semrush puts keywords, rankings, links, ads and AI visibility in one suite. mttr reads each page the way search engines and AI assistants do and puts the fixes in order. Keep Semrush for the market, and add mttr, free, for the pages.

Keep Semrush. Add mttr on top.

mttr is not a replacement for Semrush. It is a free layer that reads your pages the way search engines and AI assistants do.

What Semrush is best at

  • Keyword and competitor researchKeyword ideas at scale, traffic estimates for any domain, and where rivals win.
  • Rank trackingDaily positions for the searches a site cares about, by place and device.
  • AI Visibility ToolkitPrompts tracked in assistants such as ChatGPT and Google AI Mode, and how answers mention a brand.
  • Site Audit with AI search checksTechnical health, AI crawlers blocked by robots.txt, and a missing llms.txt.

What mttr adds on top

  • A reader for what code cannot countA reasoning model reads for things such as whether a page answers before it explains. It only advises; code decides.
  • Fixes ranked by what they are worthEach failing rule weighed by its stage and by how many pages miss it, so the first fix is the one that moves the most.
  • Structured data that fits the pageWhether each block of JSON-LD parses and whether its type fits what the page is, with a free creator that writes it.
  • A loop your agent runsThe plan in your agent’s words for Claude Code, Codex or Cursor, and 62 MCP tools: it makes each change, asks for a fresh read, and mttr says which rules now pass.

Questions

Is mttr a Semrush alternative?

No. mttr has no keyword database, rank tracking, ads or prompt tracking. It is a free layer on top of Semrush that reads each page the way search engines and AI assistants do and ranks the fixes.

Can I use mttr with Semrush?

Yes. Use Semrush to choose the searches and prompts that matter and the pages that should win them, then use mttr to fix those pages and confirm each fix on the live site.

Semrush already checks AI crawlers. What does mttr add?

Semrush Site Audit checks whether robots.txt blocks AI crawlers and whether there is an llms.txt. mttr also checks that each page’s words are in the HTML before any script, that its structured data fits it, and whether it answers before it explains, then puts every fix in order.

Is mttr free?

Yes. Reading any public site is free, with no sign-up: the first 100 pages, a score, its place and the fixes worth the most. An email gets a key, and the key connects your agent.
