Limitations and Accuracy of Semrush’s Data

Despite having the most extensive database compared to any other SEO tool, Semrush still has some limitations. One is its reliance on third-party data providers, meaning you only have rough estimates of data fetched by these providers.

Secondly, Semrush only fetches data from Google search results, limiting its data coverage. It means Semrush might miss some websites or is unable to crawl many, which impacts its data representation.

Also, Semrush does not represent Real-time data. This gap is due to the time required for data collection, analysis, and visualization. Consequently, the insights provided by Semrush may represent a delayed snapshot of the SERPs.

Considering it is a non-Google tool, The depth of data it provides and the comprehensiveness it includes is unmatched. I have yet to find a tool that accurately represents SEO and SEM statistics more than Semrush.
