Cookies 2025 chapter

[yohhaan]

Hi!

This is a (draft for now) pull request with the content for the 2025 Cookies chapter (https://github.com/HTTPArchive/almanac.httparchive.org/issues/4069). To be more efficient, the content has been drafted directly in markdown (no Google Docs). Feel free to edit on the cookies-2025 branch directly, or leave comments in your review on this PR.

Staged version: https://cookies-2025-dot-webalmanac.uk.r.appspot.com/en/2025/cookies Staged version of home page quotes and stat: https://cookies-2025-dot-webalmanac.uk.r.appspot.com/en/2025/?feat=cookies#featured-chapter

So far, the 2025 chapter is pretty similar to last year's analysis IMO, although I have pointed out to some differences I noticed. Some suggestions or ideas if people have some time to help:

• If you have a different perspective on things or time to dive deeper on a specific aspect, please feel free to make edits directly.
• Idea: correlating top cookies with info from https://cookiepedia.co.uk/ for instance.
• Idea: or investigating more these partitioned cookies from YouTube that used to be predominant, but are not anymore.
• A suggestion from @JannisBush included adding an analysis of the issue tab in Chrome Dev Tools and/or console warnings related to cookies. This has not been performed yet and I don't know if we will have time to do so.
• See also the {# TODO ... #} comments that I left in the sections that I felt could use more.

ToDos/Next steps:

• [ ] @ChrisBeeti: add the SQL queries used so far for the chapter by opening another Pull Request. Also, feel free to review chapter draft and suggest/make edits.
• [ ] @ajackley: if you manage to find some time to help with the writing and contribute, make a pass with the points above in mind.
• [ ] @martinakraus: feel free to review chapter draft and suggest/make edits.
• [ ] @JannisBush: feel free to review chapter draft and suggest/make edits.
• [ ] Someone: run this npm script to generate the chapter images.
• [ ] ask editor to make a pass
• [ ] send for review for merge with HTTP Archive Web Almanac project

Thanks!

@ChrisBeeti: add the SQL queries used so far to the cookies-2025 branch. Also, feel free to review chapter draft and suggest/make edits.

Let's add the SQL in a separate PR please. That way it can be merged ahead of the chapter and keeps this PR small.
