I Tested Similarweb & Semrush Accuracy (Real Data)
Tools like Similarweb and Semrush are widely used for traffic estimates, keyword research and competitive analysis
But how accurate are their numbers when compared to real, first-party data?
In this video, I compare data from Similarweb and Semrush with actual metrics from Google Search Console to see how close these tools really get
What I cover:
• Side-by-side comparison of Similarweb, Semrush, and GSC data
• Where third-party tools align well with reality
• Where the numbers diverge significantly
• Why these tools are useful for directional insights and research
• Why you should not rely on them for absolute traffic numbers
The takeaway: Similarweb and Semrush are powerful for research and relative comparisons, but they shouldn’t be treated as ground truth.
If you work in SEO, growth, analytics, or marketing, this will help you use these tools more responsibly.
