The title is quite clickbaity, especially since sibling comments say that the article doesn't tell what happened.

So you didn't even read an article you describe as "clickbaity"? Maybe try reading it, there's a lot of "what happened" in there.

I'm commenting on the title, not on the article (siblings did that).

Anyone know more about these 'offline passbacks'? > for certain tracking technology like hashed offline passbacks

You refer potential customers and send us a list, we tell you what they bought and how much we owe you. The hashed offline part probably refers to hashed email or other PII, so that we can exchange data without actually exchanging data.

Interesting, so like sort of like an affiliate program, but in like a bulk non-realtime way.

Is there any way from preventing under/over reporting of how many referrals were sent? Or is that just implicit in having the hashed identifier

You can try to frame it in whatever way you want, but that does not change the fact, that you have zero idea, whether or how much I support creators that I like. It would do you good to not just assume things on the basis of someone's browsing and ad blocking habits.

That's reasonable. So, out of all the content you consume, for what percentage of it do you contribute to the content's author/creator/company? How much value per year?

Enough so that, if everyone able to do the same did the same, it would pay for my and their consumption many times over.

Without hashes, there's some trust, statistics, and customer support involved. If the affiliate sender sees a lot of referral traffic from their end, and you don't report many visitors or conversions, often the affiliate providers will try and troubleshoot that to make sure you're seeing results that are in line with their other partners.

Ah, GTM. I think people might be shocked that access to this RCE backdoor is often given to non-technical roles and even outsourced marketing resources..With no controls in place at all. Security nightmare.

That's why at Sentry non-technical people don't have the ability to publish new GTM versions. It's tightly controlled because we don't want marketing to shove things in there without engineering and security reviewing.

The joys of reviewing a GTM change submitted by some Chad at "Marketers R Us" where they copied a minimized, practically obfuscated, JavaScript blob of unknown origin into the browser.

LGTM!

FML...

Also GTM can get fucked.

I don't know why sentry ads is popping up so often on Reddit. And they even turn off commenting. Very unusual for an open source developer tool.

Sentry is not open source, it's BuSL: https://blog.sentry.io/relicensing-sentry/

No, it's actually FSL

They are just very bad at targeting them. I'm a software developer so of course 90% of the ads I see on fb are for developer courses and no-code solutions to develop software… On youtube there's often the "meet east european single women" above the list of suggested videos.

You don't adblock...at all?

I do… but adblock inside fb or reddit doesn't work great

You're surprised an article about marketing is full of marketing stuff?

What many, including myself, wanted to hear is: See, tracking cookies does nothing. Instead what we got is an article that explains that companies do in fact not need cookies, they are plenty capable of tracking our reactions to advertising without them. Then there are paragraphs like this one: > We decided to rely on ad engagement retargeting (rather than traditional retargeting) on most of our ad channels which isn…

> Which for people like me is a big "WAT?" What does that even mean, what are consequences, why didn't they do this earlier?

Traditional retargeting is done discriminatory. You visited a site, got enrolled in a list, etc. and they start targeting that. Ad engagement retargeting on the other hand waits until you "engage" with the ad, meaning that you have explicitly showed interest. Is another explicit vs implicit.

Yeah, the fact that they don't have a clear indication of impact means one of two things: - Cookies weren't doing a whole lot for them to begin with, and removing their use had negligible impact. - The other work their marketing department did to try and compensate for discontinuation of cookie usage interfered with the test, making the results useless for evaluating the value of cookies. I'm leaning towards the seco…

Agree, but your second bullet is kind of the same as the first, right? It’s saying that on the whole, inclusive of changes to marketing processes, removing cookies didn’t impact bottom line enough to be measure able as positive or negative.

There's definitely a difference between "Cookies provide X value" and "We were able to mitigate the loss of cookies by doing A, B, and C - but we don't know the value of doing A/B/C individually."

If the point is to quantify the value of cookies then you need to measure that as an independent variable. Attempting to compensate with other actions, each of which you also don't know the independent value of, means you will be unable to quantify the true value of cookies or the value of your other actions.

What if none of the tools they're using, including cookies, provide any measurable value? How would you know? What if the value of cookies (X) and item A is positive in terms of impact, but B and C are both negative, but not enough to offset A so it comes out in a wash?

Indeed. Cookies are incredibly useful for things the user really does want, like staying logged in across sessions/tabs.

A login cookie does not require a consent banner, because logging in is an explicit user request. But I didn't log into Sentry in my testing.

Persisting login cookies if the user didn't explicitly consent to data collection is specifically _not_ exempted by ePrivacy. To quote a EU Working Group's opinion on this: 'Persistent login cookies which store an authentication token across browser sessions are not exempted under CRITERION B. This is an important distinction because the user may not be immediately aware of the fact that closing the browser will not clear their authentication settings. They may return to the website under the assumption that they are anonymous whilst in fact they are still logged in to the service. The commonly seen method of using a checkbox and a simple information note such as “remember me (uses cookies)” next to the submit form would be an appropriate means of gaining consent therefore negating the need to apply an exemption in this case.'
