In 2022, Google began changing the availability of the information available in User-Agent strings across their Chromium browsers. The change is to use the set of HTTP request header fields called Client Hints. Through this process, a server can request, and if approved by the client, receive information that would have been previously freely available in the User-Agent string. This change is likely to have an impact on publishers across the open web that may use User-Agent information today.
To explain what this change means, how it will impact the AdTech industry, and what you can do to prepare, we spoke with Nate West, our Director of Product.
What is the difference between User-Agents and Client Hints?
A User-Agent (UA) is a string, or line of text, that identifies information about a web server’s browser and operating system. For example, it can indicate if a device is on Safari on a Mac or Chrome on Windows.
Here is an example UA string from a Mac laptop running Chrome:
To limit the passive fingerprinting of users, Google is reducing components of the UA strings in their Chromium browsers and introducing Client Hints. When there is a trusted relationship between first-party domain owners and third-party servers, Client Hints can be used to share the same data.
This transition began in early 2022 with bigger expected changes beginning in February 2023. You can see in the above example, Chrome/109.0.0.0, where browser version information is already no longer available from the UA string on this desktop Chrome browser.
How can you use User-Agent device attributes today?
UA string information can be used for a variety of reasons. It is a component in web servers that has been available for decades. In the AdTech space, it can be used in various ad targeting use cases. It can be used by publishers to better understand their audience. The shift to limit access and information shared is to prevent nefarious usage of the data.
What are the benefits of Client Hints?
By using Client Hints, a domain owner, or publisher, can manage access to data activity that occurs on their web properties. Having that control may be advantageous. The format of the information shared is also cleaner than parsing a string from User-Agents. Although, given that Client Hints are not the norm across all browsers, a long-term solution may be needed to manage UA strings and Client Hints.
An advantage of capturing and sharing Client Hint information is to be prepared and understand if there is any impact to your systems and processes. This will help with the currently planned transition by Google, but also should the full UA string become further restricted.
Who will be impacted by this change?
Publishers across the open web should lean in to understand this change and any potential impact to them. The programmatic ecosystem supporting real-time bidding (RTB) needs to continue pushing for adoption of OpenRTB 2.6, which supports the passing of client hint information in place of data from UA strings.
What is Google’s timeline for implementing Client Hints?
Do businesses have to implement Client Hints? What happens if they don’t?
Not capturing and sharing with trusted partners can impact capabilities in place today. Given Chromium browsers account for a sizable portion of web traffic, the impact will vary for each publisher and tech company in the ecosystem. I would assess how UA strings are in use today, where you may have security concerns or not, and look to get more information on how to maintain data sharing with trusted partners.

As my colleague Jake Davis and I were planning this blog post, we had a lengthy conversation about what we were going to focus on. If you’ve experienced even one holiday season as a digital marketer, you know there’s a ton of crucial decisions to be made about your Q4 digital endeavors. Some of our clients have been planning since the end of the summer for “prime time,” and more than a few mentioned that they earn up to 40% of their annual revenue between October and December. Jake and I are both marketers – my perspective is from the strategy and planning angle, while Jake is The Man when it comes to data and analysis. Together, we make each other better by challenging each other’s ideas and perceptions. We think this blog post captures the best of both of our perspectives. Ultimately, there are a lot of variables at play all year long, but making smart decisions about creative, segmentation, deployment time, content, etc. carries a lot more weight as you close out Q4. I am interested in volume trends and thematic changes through the holiday season; because I believe marketers truly want to be proactive about crafting their holiday plans. In the real world, however, the calendar is a living document and a moving target – if a brand is not hitting its projections, course correction at the 11th hour can happen. Our goal is to ensure that type of recalibration is more the exception than the rule (and to give you some pointers even if you find the calendar is more of a guide than a concrete plan). Jake and our analytics team do some of their most innovative analysis annually, after the holiday season. That analysis of the 2015 holiday season, along with projected trends and industry developments, is what we are using to help frame this particular piece of thought leadership. With that being said, here are four charts and some explanations that can help you win by December 31st: 1. Peak Days Black Friday and Cyber Monday still have a hold on the public’s attention and wallet, even with promotions that began at the end of October. Factor in mobile shopping, and Cyber Monday in particular could be especially lucrative: mobile first consumers are ready, willing and even more able to make purchases from virtually anywhere, not just in front of their computers or tablets. But expect a decline in email marketing effectiveness from the year before…for all of the same reasons it will be so lucrative elsewhere. 2. Send size matters Batch and blast is probably here to stay, no matter how much we preach about the long-term benefits of smaller, targeted campaigns. Even the savviest marketers will resort to some large sends this holiday season, so when you do, it will serve you well to remember this maxim: volume is negatively correlated with email KPIs. Your send size might be the only reason you see a decline in your open rate – and that’s just math! 3. Animation: a key to unlocking engagement Animation has been around for a while now, but that doesn’t mean it’s any less effective. Last holiday season, mailings that included animation were clicked on 30% more than expected based on other trends. While that might because only the best mailings get this treatment, expect animation to get your customers moving. 4. Free shipping Free shipping was the most popular offer in 2015, although slightly less effective than 2014. As recent news about an increase in shipping rates reaches consumers, free shipping could prove to be even more compelling than past years. On the other hand, marketers that offer free shipping may see their bottom line affected (so prepare for Free Shipping with higher qualifiers, and remind your consumers about all the other great benefits they’ll receive by shopping with your brand). As with last year, our ultimate take-aways included the strong Jake and Liz approved suggestion to look at performance from your digital channels in a holistic sense. How have you been communicating with your customers the entire year? Is your website mobile optimized? Is your content personalized and relevant? Are you targeting the right audience? Are you using browse and abandon behavior to send triggered emails and make product recommendations? Most importantly, do you understand the context in which you’re deploying your email? It’s a competitive world out there, and most everyone has the same tricks up their sleeves. Be creative and daring when thinking of what minor innovations could prove major to your bottom line. While the charts above describe holiday 2015 (and rest assured, they will likely describe holiday 2016), it’s the tiny variations – the curious interpretations – that will drive your program forward. And when you’re struggling to come up with that variation? We’re here to help. Read more analytics posts here.
