Summary
In today's episode, I break down the cookieless future and explain why marketers should stop panicking about the death of third-party cookies. Here's what this means for you. You'll discover that shifting from demographic-based ad targeting to context and creator partnerships actually produces stronger, more relevant marketing results. You'll also learn these concepts: how first-party and third-party cookies differ, why context matters more than tracking individual users, and how partnering with creators unlocks audiences in places ads cannot reach.
Key Takeaways
- You'll learn how third-party cookies have enabled cross-site tracking and why browsers are now blocking them to protect user privacy
- You'll discover why context-based advertising outperforms demographic targeting when you place ads on the content your audience already consumes
- You'll see how creator partnerships and sponsorships can replace traditional ad-tech buying and even reach ad-free spaces like private Discord servers

In today's episode, let's talk about the cookie list future. This is a question that has been coming up a lot lately as uh browsers and platforms are announcing the reduction of support for uh cookies, particularly third party cookies. So let's let's clear the air for a bit and explain what's going on, and then talk about why this is probably not a big deal if you have your head on straight and you're using your brain to do marketing in a slightly different way. First of all, what is a cookie? In the context of marketing, a cookie is just a small piece of text, it's a text file that gets embedded on your computer when you visit somebody's website.
When you visit this website, there you get one or more of these little cookies that say, hey, you visited this website. And on this thing, it's if you think about it like a fortune cookie, right? That's that's really the amount of text we're talking about, is some kind of unique identifier that um allows services like Google Analytics, for example, to not only track you but remember who you are when you keep coming back. Right? Every time you come back to the website, um, software like Google Analytics will look at your browser and say, hey, I see a cookie here from myself previously that I gave you.
Yep, you're the same person, so I know you're a returning user versus a new user. Now there's two general classes of cookies: first party cookies and third party cookies. A first party cookie is when a website gives you a cookie from itself. So if you were on trustinsights.ai and there was a cookie called trust insights.ai, that would be a first party cookie. I gave you this cookie, right?
Um, and so my systems can can talk to it and you know manage your preferences and you know, give you the ability to set certain settings and things like that. It's a first party cookie. A third party cookie is when you get a cookie from a website that you're not necessarily on. So again, you go to the Trust Insights website, you the site loads Google Analytics. Google Analytics, which is over on Google.com, issues you a cookie and says, hey, here's a cookie.
You're on the Trust Insights website, but obviously Trust Insights has installed Google Analytics, so here's a cookie. That cookie is from Google.com, not TrustInsights.ai, and therefore is a third-party cookie. If I was running my own web analytics software on the Trust Insights website, and it was like analytics.trustinsights.ai, that would be a first-party cookie. Third-party cookies have gotten a bad rap because a lot of the time, particularly on big publishing sites, other people are giving you lots of cookies, lots of identifiers, lots of ways to track you. So let's say you go to my personal website from the Trust Insights website.
The domain changes from TrustInsights.ai to ChristopherSPenn.com. Google Analytics gives you a cookie. And then Google looks there and says, hey, you're the same person that was on the Trust Insights website. So it sees that you travel to a different website. And now you can see how it's starting to track you from place to place.
Now when you go from there to CNN, or when you go from there to um you know Time magazine, we go from there to ESPN, that cookie keeps going with you, the Google Analytics one as you go from site to site to site, and Google goes, hey, you're the same person. I'm gonna track of all the places you've been. This obviously, for good reason, has caused a lot of concerns about privacy, right? Suppose that I go to target.com and then I go to Walgreens.com and then I go to PlannedParenthood.com and suppose that you're collecting data all along the way. What might you infer about me?
Suppose after I go to Planned Parenthood, I go to a fertility clinic. What might you infer about me based on the patterns of where I'm going? And third-party cookies enable this. Every one of those sites would be allowed to track me on their site from that organization, right? If I'm on Target.com, Target's allowed to track me on the Target website, but should Target be allowed to track me on the Planned Parenthood website.
The reason why people are saying no more third-party cookies is because they're saying we don't want to know, we don't want Target to know when I'm on the Planned Parenthood website or when I'm on a fertility clinics website. We only want Target to know when I'm on the Target website. And so first party cookies, okay. Third party cookies, not so much. So that's what the in a nutshell is going on.
There's a bit more, you know, technical architecture to that, but that's essentially what's going on. What's happening now is that systems like Apple's iOS, uh, Safari browser, Google Chrome, and out support coming soon, uh, Firefox, the other browsers have said, hey, we're gonna reduce the ability for third-party cookies to track people. If you use an ad blocker of some kind, ad blocking software, those also block third-party cookies, which means now that these companies that aggregate data and resell it to marketers are losing their ability to track you from site to site. Right? There are all these ad networks that have that partner with places like CNN or Fox News or whatever, and you know, they get that millions of people funneling into these big publisher sites, and they have all these ad tech companies you know, throwing cookies on your computer left and right, so that they can all track you from site to site and build profiles and track you across the web.
And the reduction of third party cookies, which is what's going on now, is essentially saying, yeah, that's not allowed anymore. Not allowed anymore. Which is good for privacy. Not good if you're a marketer who relies on that data, right? If you're trying to quickly and easily build a list, I need to show ads to people who are 40, mid 40s uh Asian men who go to target.com or you know shop for home goods or are are interested in firearms, whatever the thing is.
It used to be easy for marketers to go to an ad tech system and say, I want to buy a segment of people like this and show them ads for my thing because I think that's who is interested in my thing. Now that those capabilities are going away. As a consumer, I'm okay with that. I'm I'm perfectly okay if companies are having a harder time tracking me. What about as a marketer?
Do I care? I don't. And here's why. Everything that we do with content online as marketers has context to it, right? Content isn't just you know featureless bland destinations.
It's it's stuff that people are interested in. So if you know your customer, you can talk to your customer, find out what they're interested in, and then you target not the customer, not the list, not the cookie, but the content itself. So let's say um you're somebody who's really interested in headphones. Do I need to know? Do I need to put a cookie on your browser and track you from site to site if I know that you're interested in headphones?
Probably not. If you're interested in headphones and you're on, say CNET's website reading headphones reviews, and I'm a manufacturer of headphones, where should I buy ads? Right? Should I buy ads on uh Home and Garden magazine? Not necessarily.
Should I buy ads on CNET? Maybe. Should I buy ads on CNET's headphones articles? Uh-huh. You betcha.
Because I know if my audience is interested in these things and they're looking for information, I can just show ads on the context relevant pieces of content. And I don't have to worry about cookies. I don't care where you go next, right? I don't care uh what other things you're browsing for that day. But if you're on an article that's talking about the best headphones for airplanes, and I've got the best headphones for airplanes, I should be showing ads on that place.
That's pretty intuitive. Extend it a step further. Suppose that you're an influencer, right? You're a YouTube creator, you do gear reviews, um, and you're you're uh showing all these, you know, your review of all these different kinds of headphones, and maybe mine's not in the lineup, maybe I'm a new company. If I'm going to run YouTube ads, whose channel should I run ads on?
Yours. Yeah, if you're a creator who's reviewing headphones and I've got headphones for sale, it seems pretty obvious I should be running ads on that content. Maybe I could take it a step further. Maybe if you are uh a headphone aficionado and you have a uh uh you know just hanging out channel on Twitch, maybe I should sponsor you as a creator and say, hey, you know, Chris's headphone channel brought to you by Chris's headphones. Again, this is not rocket surgery.
This is finding out what affinities our audience has, then going to the places where the content lives about those things and running ads there. You don't need cookies for that. You barely need you know uh banner ad systems that are more sophisticated than the ones that came out in like 1998. Show your ads in the places where people go to learn about your class of product, and you don't need to track people. Sponsor newsletters, sponsor social media posts by people who have your audience.
The thing about the creator economy, the thing about all these different personalities and stuff in the creator economy is that they all have audiences, they're doing the hard work of attracting a like-minded audience. We as marketers, we don't have to do that anymore, right? We don't have to go to an ad tech system and buy 15 different segments. We can say Adrian has got a gaming channel on Twitch that covers these games from our own market research, talking to our customers. We found out our customers really like Minecraft.
Adrian's got a Minecraft uh show on Twitch. Let's go sponsor Adriana's channel. And we Adrian has done the hard work of getting the eyeballs, getting the crowd. All we have to do is compensate Adriana appropriately, if she takes ads, to run ads to her audience, to bring in new audience. So that's where advertising and marketing has to pivot to.
Away from the demographic, away from the market segment, and focused on the content and the context, right? Who has the content that is consumed about our product and service? Right? If I am running, if I'm building creating a new course on data science, maybe. Who talks about data science?
Whose YouTube channel? Who's Twitch channel? Who's Patreon or Gumroad or Substack or OnlyFans or whatever? Who's got not my audience that I want to be able to reach out to and say, hey, I've got a thousand bucks, five thousand bucks, fifty thousand bucks, whatever the case is. Can we partner?
Can we collaborate? Can we do something? Can I run ads to your audience? Because you've done the hard work of building a data science audience that I want to get access to to sell my course. That is the cookie list future.
It is not an advertising-free future. And in fact, if you focus on the content and the creator, you'll be able to advertise in places that don't allow ads. For example, my friend Siwa's got a Twitch channel where she streams her gaming stuff, but she's also got a Discord server. And on her Discord server, guess what? No ads.
None. There are no ads there. There's no ads on Discord, period. Now, suppose I said, hey, I want to sponsor your channel for the next 30 days. Here's five grand.
Uh to I want to reach, you've got it, the crowd that I want. Can we work out where maybe you do a partner announcement in your Discord channel? Uh you know, just at everybody. Guess what? Now, in a media environment where there are no ads, I get to be the only advertiser because I figured out that if I partner with the creator, I can reach into all their channels if I pay them enough.
And there's no competition. I don't have to probably, I probably don't have to worry about another competitor in those private places because I've I've worked with the creator, the hub of that network, to reach into all the different areas of their network. So the cookie list future might be a blessing in disguise for marketers. It really might be because it forces us to change from our lazy habits of just buying up swaths of people who may or may not even be interested in what we have to offer because you know all these ad tech algorithms are based on only observed data. And if we are clever and we're willing to work hard and we're willing to really do our research, the cookie list future might be a blessing in disguise for us to be able to pivot to much better marketing.
