Why Is My Google Analytics Event Data Inaccurate?

Have you considered using something like Supaboard? It allows you to directly visualize your Supabase data, so you might get a clearer picture.

Analytics tools often can't guarantee 100% accurate data. There are a few reasons this might happen: sometimes network issues prevent events from reaching Google Analytics servers even if they hit yours, and commercial analytics tools can filter out bots—which won't always be precise. Also, don't forget that Google Analytics uses some sampling methods, which can further skew data.

Also keep in mind that ad blockers can block primary tracking like Google Analytics, which means you’ll miss some data there. Plus, as others mentioned, various network issues and filtering might impact the stats you see. First-party tracking is usually more reliable than third-party.

The way you're collecting click data can also influence accuracy. If you’re capturing clicks through a navigable endpoint, you might end up counting bot traffic or users with tracking disabled, even if everything's sent via JavaScript.

GA isn’t designed for 100% accuracy anyway; it's more about spotting user behavior trends than pinpointing exact clicks. For precise event tracking, you might want to manually count events or try using Heap Analytics with a setup to bypass ad block issues.
