This article is part of a series of articles about Core Web Vitals.
In our previous article, we covered what good Core Web Vitals are and why they are important. By now, you should be at least looking to measure how each of your web pages scores across the (3) primary influential metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Shift Layout (CSL). Now, it’s time to understand what affects the scores in each of these areas and how to isolate and fix these factors.
We made this article more "list-like" so that you could just print this out or paste it into a punch list for review. Core Web Vitals aren’t a simple fix unfortunately - primarily because it requires looking at EVERY page of your site that you want visitors to be able to find in search results (which should be the majority, if not all, of your website).

What Affects LCP?
How to Optimize / Fix Largest Contentful Paint (LCP):
A Low FID score is anything taking longer than 1.1 seconds to complete, and if FIDs are longer than 3.0 seconds, Google penalizes your page, which affects your page ranking and discoverability within their search algorithm.
What Affects FIDs?
How to optimize / fix First Input Delay (FID):
A Low CLS score is anything greater than .1, and if CLSs greater than .25, Google penalizes your page, which affects your page ranking and discoverability within their search algorithm.
What Affects CLS?
How to optimize / fix Cumulative Layout Shift (CLS:
Remember, in order to pass the Core Web Vitals assessment, you need to score “good” for ALL THREE Core Web Vitals—Largest Contentful Paint (LCP), First Input Delay (FID) and Cumulative Layout Shift (CLS).
Also, remember that these Core Web Vitals scores are for each page of your site individually.
