Free SEO competitor analysis tool

A free SEO competitor analysis tool reports which domains rank against you in search, and which keywords they rank for, at no cost. Every free tier of this kind is capped rather than unlimited.

The caps are published in three units: how many competitors you may track, how many of their keywords are reported, and how often those keywords refresh. Seobility's free Basic plan tracks 3 competitors and reports competitor rankings for 10 keywords, updated weekly. Moz's Keyword Gap tool accepts up to 3 competitors, and Moz lists Competitive Research among its free SEO tools.
