Vercel analytics data much higher than another analytics

[pepelele]

Hi, I wonder how Vercel Analytics calculates visitors and pageviews. I test with Vercel and it got 7k visitors and 70k pageviews per day but with Fathom or Google Analytics (the data of both platforms is quite similar) I just got 4k5 visitors and 40k pageviews... why is it so different?

Hey!

Because GA and others are mostly blocked by adblockers and we are not!

This is because Vercel Web Analytics works with an first-party intake (page views are tracked over the same domain as your website)
