What are Core Web Vitals?
Posted: Sun Feb 02, 2025 8:08 am
The methodology we applied for this study can be summarized as follows:
We accumulated 10,000 random keywords from Semrush Sensor US database for desktop and mobile.
The keywords came from many different categories/niches and varying search volumes.
SERPs were analyzed and collected on February 15, 2021.
For each keyword, we collected the top 10 results/top 10 URLs from the SERP, which is approximately 78,000 desktop URLs and 78,000 mobile URLs.
For all collected URLs, we analyzed the three Core Web Vitals metrics: LCP, TBT, and CLS.
Please note that TBT replaces FID in the Semrush tunisia telegram number database Site Audit tool , as Google prefers to use TBT. It is a more accurate metric for benchmarking and optimization. Read Google's optimize FID for more information.
This study was conducted with “lab” data, meaning we did not collect data from a Google API.
The data is displayed by a web page, not the entire website. This is important because Core Web Vitals are page metrics, not site-wide metrics. This is crucial to understanding whether the metrics are scoring “Good” or not for each given page at a time.
This study was conducted before these metrics impacted the results of the June update. With this data, SEOs and site owners can prepare their sites for the update.
