On 31 January, Google’s Q4 report to the UK CMA was released. The report provides much-needed updates on the User-Agent reduction and User-Agent Client Hints. We recap the key points from the report in this blog.

Chrome 110, due for release on 1 February 2023, will be the first Chrome version that has information removed from the mobile and tablet User-Agents. In essence, you will not be able to tell the difference between different mobile or tablet device models.

Google is pressing ahead with the User-Agent reduction. From February 2023, Google will reduce the information within Chrome mobile and tablet User-Agent strings. Device information will only be available through User-Agent Client Hints.

If you have not adjusted your systems to support User-Agent Client Hints before the release of Chrome 107 on 25 October 2022, you are likely to encounter a reduction in your device detection accuracy.

The webinar, and this transcript, serves as an extensive history into why Google are reducing the User-Agent in favor of their own creation, User-Agent Client Hints.

In this webinar, we’ll discuss Google’s User-Agent Reduction and User-Agent Client Hints proposals. Both are a big change, whether you are a website owner, web analytics professional, or performance optimization specialist, you will need to prepare. Join us on 28 September to learn more.

User-Agent Client Hints return device information in the second request rather than the first; this can cause latency issues. We discuss why Google need to address the latency and offer a work-around.
