Look at the cached version of the SERP. There are times I do a search in my city and the results are not what SEMRush is saying however, when I am at my office and do the search the results much more closely match. My office is in the same city as my home. However, the search results can favor by neighborhood.

With tools like SEMRush you will need to also monitor daily volatility of SERPs as well as the differences in the cached search. There are a good amount of insights to be gained there.

Another thing to consider is that SEMRush, AHREFs, MOZ and all these tools are only so accurate they capture a position once a day or every couple days depending on the app. That snapshot is not live and comes from a fixed location. Using the API these tools have and aggregating the results from multiple tools is the best way to gain “accuracy”.
