This means that you may get more "fine-grained" keyword difficulty information from Semrush, although it's unlikely that you'll ever find it useful, as this kind of information is usually only used in super-competitive niches.
Semrush and Ahrefs both allow you to create lists of keywords that you can reference at any time (using the Keyword Manager and Keyword List features, respectively), as well as view changing keyword difficulty scores.
So far we're talking about a fairly similar el salvador phone number list feature set when it comes to keyword research. But both products have some nice keyword-related features that the other doesn't.
What's really cool about Ahrefs' approach to keyword difficulty estimation is that it not only tells you how difficult it will be to rank for a given keyword, but it also tells you roughly how many backlinks you need to build to appear on the first page of search results.
Ahrefs' Keyword Difficulty Score comes with an estimate of how many links you'll need to rank in the top 10.
Additionally, Ahrefs shows not only search volumes, but also the number of clicks they can generate, something Semrush does not provide.
