 To isolate your UTM-tagged clicks from other clicks, you can segment the traffic by using the "**UTM Medium**", "**UTM Source**" (here you can also see any traffic tagged with "ref" and "source" parameters), "**UTM Campaign**", "**UTM Content**" and "**UTM Term**" sections in the "**Campaigns**" tab of the "**Top Sources**" report.
 
 P.S. If you are looking to specifically track Google Ads with Plausible, you can also go through [this guide](https://plausible.io/blog/google-ads-tracking).
