Referrers panel seems to not be getting data

[bartvdbraak]

I have implemented Vercel Web Analytics on my personal website (https://github.com/bartvdbraak/hellob.art)

However, I don't seem to be getting any referrer data for it. If I inspect the API calls being made, they look as follows:

curl 'https://hellob.art/_vercel/insights/view' \
  --data-raw '{"o":"https://hellob.art/?ref=github","sv":"0.1.2","sdkn":"@vercel/analytics","sdkv":"1.0.1","ts":1690662958930,"r":"https://github.com/"}' \
  --compressed

Even when I am coming from GitHub, which does populate the Referer header on my first document GET request:

curl 'https://hellob.art/?ref=github' \
  --compressed \
  -H 'Referer: https://github.com/'

What is Vercel using to gain these data points? Am I doing it wrong?

Hey, can you still not see any referrers showing up? When its set (readable via document.referrer) you should see it. Let me know!

It does seem that that doesn't get populated when browsing with Firefox:

@bartvdbraak yeah, thats a privacy thing and a lot of pages/browsers don't pass any referrer anymore sadly. thats nothing we can do about this

[bartvdbraak]

Ah fair enough.. Is there any way I can implement this using query parameters in the links on other sites?

For example: https://hellob.art/?ref=github.com

Not sure if I can make the /view api call for Vercel Web Analytics interpret that correctly in any type of way.

@bartvdbraak yes you could do that, although we're not showing ref or utm params yet, but this might come soon! (data will be stored already)

Hi @tobiaslins could we explore these stored data somewhere in the mean time? Thanks in advance.
