We removed advertising cookies, here's what happened

While they removed cookie banners and say they no longer include dependencies that set cookies, browsing around the site for a bit I still see several cookies set. For example, visiting <a href="https:&#x2F;&#x2F;changelog.getsentry.com" rel="nofollow">https:&#x2F;&#x2F;changelog.getsentry.com</a> I get first-party cookies &quot;_GRECAPTCHA&quot;, &quot;ph_phc_UlHlA3tIQlE89WRH9NSy0MzlOg1XYiUXnXiYjKBJ4OT_posthog&quot;, and &quot;_launchnotes_session&quot;, plus third-party cookie &quot;_GRECAPTCHA&quot; on recaptcha.net.<p>Similarly, visiting <a href="https:&#x2F;&#x2F;try.sentry-demo.com" rel="nofollow">https:&#x2F;&#x2F;try.sentry-demo.com</a> I got cookies &quot;sentrysid&quot;, &quot;sc&quot;, and &quot;sudo&quot;.<p>I also got a player.vimeo.com cookie at some point, but wasn&#x27;t able to reproduce.<p>If you&#x27;re running a complex modern site and decide to do away with cookie banners, you generally need to pair this with browser automation that crawls your site and verifies that you (and your dependencies) are in fact not setting any cookies.

So Google AdWords performance absolutely tanks with the sunsetting of 3rd-party cookies…<p>It looks like this mostly happens because they lose the conversion signaling which is the most important input to their bidding model, making them pay for 4x as many impressions which still only concert to 1&#x2F;10th the sales.<p>Is this the experience that all Google AdWords customers will be waking up to later in 2024? It sounds like Sentry is being pro-active and getting ahead of the curve, and not just cutting their advertising performance for purely benevolent anti-tracking reasons.<p>When this happened to FB they lost tens of billions of dollars. Will the impact to Google be even greater? If there’s anything that could truly disrupt Google, destroying AdWords ROI has got to be their #1 existential risk.<p>It’s not like their search experience is even that decent anymore. It would make me quite happy to see Google peak as a company due to internet privacy initiatives winning out over invasive corporate panopticons.

&gt; 42.7% of internet users worldwide use ad blockers.<p>Given how many people I know that still type google into the google search bar, I find this number to be extraordinarily high.

If anyone started reading and also got confused like me. Chrome change will affect third party cookies, not all cookies.

Funny that the site tries to load some garbage from googletagmanager.com

I came to the comments for the summary only to find out there is no summary...

The title is quite clickbaity, especially since sibling comments say that the article doesn&#x27;t tell what happened.

This article is too long and packed with marketing crap to wade through.

Article mentions Sentry&#x27;s shift from tracking to &quot;brand and awareness marketing&quot;. Thanks to their recently acquired Syntax Podcast (recommended), I am now quite aware of their brand. Seems like a positive, creative approach to marketing. I wonder if there is a noticeable &quot;Syntax effect&quot; in their business metrics.

The most interesting part of this article personally was &quot;Google&#x27;s getting rid of cookies&quot;. Wait, what? How is this the first time I&#x27;ve heard of this?<p>Apparently the move is already delayed until Q2 2024 (lots of pushback at the office) [1] However, it&#x27;s still difficult to believe. Must be an utter nightmare for people who built their entire business stack on cookies.<p>[1] <a href="https:&#x2F;&#x2F;techcrunch.com&#x2F;2022&#x2F;07&#x2F;27&#x2F;google-delays-move-away-from-cookies-in-chrome-to-2024&#x2F;" rel="nofollow">https:&#x2F;&#x2F;techcrunch.com&#x2F;2022&#x2F;07&#x2F;27&#x2F;google-delays-move-away-fr...</a>

Reading headlines like this my disappointment is immeasurable and my day is ruined.

I&#x27;m not a developer and have no use case for your service but thanks for the forward thinking, experimenting, transparency, and efforts to improve one of the things that enshi*ified the Web.

TLDR;<p>Performance tanked. Targeting and optimisation dwindled, measurement became directional last click. They still switched to solutions that leverage IP Addresses.<p>As they burned through their marketing budget, they focused on bogus metrics like dwelltimes and patted eachother on the back.<p>Fun times ahead.

Anyone know more about these &#x27;offline passbacks&#x27;?<p>&gt; for certain tracking technology like <i>hashed offline passbacks</i>

&gt; <i>We market to developers who notoriously do not like being marketed to (we should know; we are a developer-led company and Sentry users ourselves), so the idea of removing ad cookies instantly intrigued us.</i><p>Ooh, they&#x27;re going after that anti-marketer market. That&#x27;s a huge market! Look at our research!

You&#x27;re just fighting over everyone else who doesn&#x27;t adblock at that point.

I don&#x27;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.

Huge “Thank you!” to Matt and Sentry for writing and sharing this article. Should our paths ever cross, the drinks are on me.

Thanks for sharing. Appreciate you taking the time to share your experience and results.

That&#x27;s a long winded article.

I have a campaign with a UTM link, once the user lands on our page we save this UTM as cookie and then we persist on our db at sign up.<p>Is this complaint with GDPR and will it still possible in the future?

I kept waiting for their findings but halfway through it&#x27;s just a bunch of self-gratifying talk and deflecting talking about why they think it&#x27;s important - I read for two solid minutes without them getting to any hard numbers or findings.

Can I voluntarily register somewhere and profile myself for the purposes of ad targeting? I&#x27;d really hate to just get completely random ads everywhere.

EDIT: classic, didn&#x27;t dig into the context, assumed Sentry was some ad ecosystem middleman -- apologies for the below (will leave as it was because there are child comments). These guys have a real product doing real things.<p>----<p>It&#x27;s fascinating to me how this org (and so many others) are hard at work, day in and day out, basically shovelling garbage into peoples&#x27; faces. They produce absolutely nothing of value (other than, arguably, the parasitic relationship which allows Free Content), but so much money flows through them.<p>I wonder what effect the exclusion of third party cookies will have on the dark patterns that are so prevalent -- but I doubt it will be much. We may have &quot;free&quot; access to so much information online, but we pay a terrible place as the quality of discourse has devolved into antagonistic feces-flinging in most of the big walled gardens, and majority of the open forums. It seems only the domain-specific, niche places still maintain a quality noise-to-signal ratio.
