Competitor tracking
Competitor rank tracking on keywords you already watch
Save a competitor and your site stays pinned at the top of the grid, so you can see who is at 3 when you are at 8 on the same keyword.

For example
Type a rival's domain in, or let Auto-add suggest the sites yours already competes with. The compare grid then shows every keyword you track with their position beside yours, and your column stays pinned so you always have something to read against.
The keyword gap
The gap is the set of keywords a rival ranks for and you do not. Starter splits it two ways: Missing is where they rank and you are nowhere, Losing is where you both rank and they sit higher. Press Track on a Missing row to start watching that keyword yourself.
Traffic next to each other
Also on Starter. Monthly visits for you and each saved rival on one line, with keyword count and domain authority beside it. It reads the same site review the Overview uses, so there is nothing extra to run.
