The practical differences
Where they really differ
Three differences worth considering before you change tools.
Website quality scope
Insight

Semrush
Semrush has a substantial SEO audit and performance checks. Coverage of other quality areas varies by product and plan.
After the result
Insight
Priorities and tasks lead to another measurement on the site.
Semrush
Semrush compares crawls and shows progress. Content and link plans still need team decisions.
