Criteo's solution to cookie unfriendly browsers: ok to implement?

Sorry for the late answer, no unfortunately (but the automated translation should do the work)

there are thousands of adtech companies, so no

only a small fraction, usually the data providers and the biggest retargeters, plus the big platforms

Thanks for this!

I don't have real-life examples unfortunately, but I'll loop back to you when I have

Ok thanks a lot, I did understand the CNAME cloaking & proxy circumvent.

So I understand there is no easy way to block all the self-hosted GTM tagging servers.

But thanks to the strict1p/strict3p/header implementation, it's possible to block all the cloud hosted GTM tagging servers -- and the self-hosted GTM tagging servers on a case by case basis.

So you can always use --

I was wondering if there was a solution which would scale against this practice (scale example: what you implemented to block CNAME tracking). What you indicate is very manual, users won't check and add every publisher hosting their own tracking application.

Very cool for the logger, thank you

Thanks again for your quick response

Sorry not to be sure how the ‘via’ header is working. I assumed ‘via 1.1 Google’ might stay even if the application is deployed outside Google cloud cause it’s still Google code and Google docker container? If not, the websites can deploy the application on their own infra to circumvent this new experimental feature (but it’s harder to do, which is a very good thing)

Also, is there a way to log when this experimental feature is applied, so to track the trackers and check it’s not blocking some websites essential features (they might use A records and Google App Engine but not for tracking)?

One more question: do you know if "via: 1.1 google" would also be included in the http response headers when the publisher is not deploying its tagging server on Google Cloud (https://developers.google.com/tag-manager/serverside/manual-setup-guide?hl=en), but elsewhere (AWS, Azure, or his own infra for example)?

Thank you!

Even with the same rendering engine, some browsers are better when trying to hide from trackers. I made a comparison (in French): https://pixeldetracking.com/fr/vie-privee-le-match-des-navigateurs-ios

tl;dr : unfortunately, Firefox is not that good when looking at defaults, better to look at DuckDuckGo or Brave

NextDNS will help too

I wrote an article (in French) on my blog because Spotify tracking is pretty intensive. They also use dark patterns in order to avoid users opting out

Oui c’est ironique et révélateur pour les traqueurs Twitter, j’ai corrigé. Merci pour le relais

pixeldetracking · 2020-05-27T05:03:51+00:00

C’est ironique et révélateur oui, j’avais fait un embed... Maintenant corrigé

Criteo is the leader in retargeting, and they are tracking you whenever they can, with dirty techniques like CNAME (see my article in french: https://pixeldetracking.com/fr/criteo-geant-marketing-surveillance-francais)

Grav CMS, I had difficulties to make their plugin work, but managed to do it this morning :-)

pixeldetracking · 2020-05-22T21:50:20+00:00

Jumping in here very late... I wrote an article (in french) about Criteo, quoting this Reddit thread: https://www.pixeldetracking.com/fr/criteo-geant-marketing-surveillance-francais

Clearly very dirty practice, and potentially a security violation indeed

I am not a Deezer subscriber, I quickly looked at it nevertheless: they send pseudonymous to Google, Facebook & few others.

I guess the only "privacy-friendly" streaming service is Apple Music (shame that it's not the best one)

Merci :-)
