For the purposes of our testing, we standardized keyword queries across the five tools. To test the primary ad hoc keyword search capability with each tool, we ran queries on an identical set of keywords. From there we tested not only the kinds of data and metrics the tool gave, but how it handled keyword management and organization, and what kind of optimization recommendations and suggestions the tool provided.
However, that’s totally impractical for established sites with hundreds of pages, so you’ll need a tool to do it for you. For example, with SEMRush, you can type your domain into the search box, wait for the report to run, and see the top organic keywords you are ranking for. Or, use their keyword position tracking tool to track the exact keywords you’re trying to rank for.
