My page is fast. Why do I see warnings on the Search Console Core Web Vitals report?

Different devices, network connections, geography and other factors may contribute to how a page loads and is experienced by a particular user. While some users, in certain conditions, can observe a good experience, this may not be indicative of other user’s experience. Core Web Vitals look at the full body of user visits and its thresholds are assessed at the 75th percentile across the body of users. The Google Search Console Core Web Vitals report helps report on this data.

Depending on how you’re evaluating “Fast”, remember that Core Web Vitals is looking at more than speed. For instance, Cumulative Layout Shift describes users annoyances like content moving around. Additionally, you may also use synthetic-based testing tools that try to emulate a user, but that representation may differ from your real users.
