If your website has poor scores on the 3 Core Web Vitals, it may be less visible in search results and may rank lower than other websites that have better performance. This is because Google has announced that it will use the Core Web Vitals as ranking signals in its search algorithms, starting in 2021.
However, it’s important to note that the Core Web Vitals are just one of many factors that can affect a website’s ranking in search results. Google uses a wide range of signals to determine the relevance and quality of a website, and the weight that it assigns to each signal can vary over time.
If your website has poor scores on the Core Web Vitals, it’s a good idea to try to improve them as much as possible. There are many techniques and best practices that you can follow to improve the performance of your website, such as optimizing images, minimizing the use of large JavaScript libraries, and reducing the number of server roundtrips. Improving your website’s performance can not only help with your search rankings, but it can also lead to a better user experience and potentially higher engagement and conversions.
