Google intends to roll out a major new ad targeting system called Topics to replace their Federated Learning of Cohorts (FLoC) proposal.
Let’s talk about how Topics is poised to change the future of online advertising going forward.
The new Topics API will be used to bridge the gap between internet users that are more privacy-minded than ever before, and advertisers that have long understood some restrictions on the data they collect (and how that data is used) have always been an inevitability.
Topics API will leverage individual browser activity to come up with a handful of topics (general content groups, like Investing, Travel, Sports) that best represent how a person has used the internet over a week span of time.
Right now, there are approximately 350 topics included in the Topics API initial design.
Let's have a look at this picture to understand how would topics be curated and selected:
Here’s how the Topics API works on both the client and server side of things:
The Topics explainer proposes that each topic object in the array returned by document.browsingTopics() would have three properties:
In order for document.browsingTopics()to return one or more topics, it must be called in code from the same origin as code that was on a site where those topics were observed.
There are major differences between the new Topics API and the previous Federated Learning of Cohorts (FLoC) system that was originally introduced by Google in March 2021.
The original push for FLoC bubbled up over the concerns of Google Chrome committing to eliminate third-party cookies by 2023.
Google wanted to improve user privacy, grouping individuals into large cohorts in an effort to provide them with a little extra online anonymity. This move would have significantly improved user privacy – but there was a lot of pushback regarding FLoC from the advertising industry at large.
Google also decided to move away from FLoC after groups like the Electronic Frontier Foundation found that it was possible to “fingerprint” individual users within these cohorts and establish unique identifiers for that user (and their individual browsers).
This almost completely negated the benefits that FLoC was intended to provide without improving the search experience for anyone.
Now, Topics is designed to give a lot more end-user control over:
Google is currently creating a number of tools for the Chrome browser that will allow end-users to see all of the individual topics that have been connected to their browser history.
Users will have the ability to disable, remove, or prohibit certain topics from connecting to their browser history as well.
There are no current plans in place to allow users to add themselves to different topics (and improve the targeting of advertising on the end-user side of things), but that may be something Google ads later down the line.
The end result is (hopefully) improved privacy for end-users a little more control over personal data, all without making it impossible for advertisers to reach their customers effectively.
Advertisers are (understandably) a little bit hesitant to jump on board with Topics just yet.
The biggest concern advertisers have right now is the lack of topic diversity that Google will launch this program.
As of right now (early February 2022), the initial Topic API is intended to launch with right around 350 individual topics. That should be enough topics for most advertisers to get a “broad range” of potential prospects, but it’s not the laser focus or scalpel approach that advertisers are used to.
Online advertisers are nervous about wasting large chunks of their marketing budget on prospects they have little to no chance to convert.
Another concern advertisers have is the limited timeframe of topic connection they are working with.
Depending on browser usage, an individual may only be targeted for a specific topic within a 123 window week of time. Advertisers are looking at something that could be much more directionally accurate than anything else, but that too could improve with time.
Finally, Google’s promise that there’s always a 5% chance that a random topic is returned for each individual browser instance tells advertisers that they may be “pitching to ghosts” from time to time.
This is done in an effort to provide more anonymity and more security. On the flip side, though, it’s going to hurt businesses' conversion rates. There’s no doubt about that.
