Keep Surfer. Add mttr on top.

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

What Surfer is best at

  • Content EditorA draft scored as you write against the terms, headings and length of the pages that rank.
  • Briefs and topical mapsWhat to write next, and how to cover a subject.
  • AI TrackerPrompts tracked across ChatGPT, Gemini, Perplexity and others, and the sources they cite.

What mttr adds on top

  • Pages read as an AI crawler gets themThe words in the HTML before any script, whether robots.txt and the firewall let GPTBot, ClaudeBot and PerplexityBot in, and one address for each page.
  • 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.
  • Signs of generated textHidden characters, chat and markdown left in, placeholders never filled and stock phrasing, page by page.
  • 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.
