Introduction
This test examines how many cookies are placed if all cookies are accepted. From a privacy perspective, the fewer cookies are placed, the better.
Method of measurement
For this test we visit the homepage of the speed test in Google Chrome, accept all cookies, and then count the number of cookies found with Get cookies.txt LOCALLY.
Because we suspect that the number of cookies placed may vary over time, we test the number of cookies placed several times (at different days) to get a better idea of the number of cookies placed (In our analysis we will use the minimum number of cookies counted).
Speed tests to test
Because this is a relative simple test, the unique speed tests as collected at ZOMDir will be tested.

How many cookies is normal?
Research from 2018 shows that the median user receives around around 10 cookies per visited website.
To check whether 10 cookies per website is still correct in 2024, we do a short sample of a number of popular websites (after accepting all cookies).
- Google 6 cookies
- YouTube 6 cookies
- IMDb 6 cookies
- Wikipedia 4 cookies
- Reddit 8 cookies
- Yahoo 9 cookies
- Amazon 11 cookies
- Bing 17 cookies
- eBay 20 cookies
- Weather.com 20 cookies
- Fandom 42 cookies
- CNN 44 cookies
- GitHub 5 cookies
- MSN 15 cookies
- Canva 24 cookies
- Walmart 33 cookies
- DisneyPlus 26 cookies
Based on the above sample, the median of cookies placed per visited website is 15. Hence we concluded that 10-15 cookies per website is normal nowadays.
Conclusions
Based on the above measurements, we conclude that for the tested speed tests:
- The minimum number of cookies is 0
- The maximum number of cookies is 27
- The average number of cookies is 8.6
- The median of the number of cookies is 6
The 6 speed tests below fully comply with the cookie law because they do not use cookies at all:
