What's in this report

The report starts with a whole-site monthly visit estimate. Search visibility and public site facts follow when they exist.

  • Website traffic is a modeled whole-site estimate, with a source, observation period and confidence.
  • Search visibility is ranking keywords and search traffic, listed separately from whole-site visits.
  • Missing or partial values stay marked in the report.
