There are no absolute “good” or “bad” scores for Core Web Vitals, as the acceptable performance range can vary depending on the nature of the page and the needs of its users. However, Google has provided some general guidelines for what it considers to be “good” performance for each of the 3 Core Web Vitals:
- Largest Contentful Paint (LCP): Google considers a good LCP score to be anything under 2.5 seconds.
- First Input Delay (FID): Google considers a good FID score to be anything under 100 milliseconds.
- Cumulative Layout Shift (CLS): Google considers a good CLS score to be anything under 0.1.
Keep in mind that these are just general guidelines and that the specific performance requirements for your website may vary. It’s a good idea to monitor your website’s performance using these metrics and to try to improve them as much as possible, but it’s also important to consider the needs of your users and the nature of your content.
