Core Web Vitals in plain words, what Google measures on your site
Core Web Vitals are a set of three measures Google uses to assess how fast and comfortable your site is to use. They affect search rankings, but above all they describe something every visitor feels: whether the site loads smoothly and does not "jump" under your fingers.
Three metrics without jargon
- Speed of content appearing (LCP), how long you have to wait for the main element to load, e.g. a large image or a heading. The faster, the better.
- Response to a click (INP), whether the site responds immediately when you click something, or "hangs" for a moment.
- Layout stability (CLS), whether the content does not jump around during loading (the classic: you go to click, and the button escapes because a banner just loaded).
What most often ruins them
The same things are usually to blame: heavy, unoptimised images, an excess of scripts (especially external ones, chats, ads, widgets), no cache and weak hosting. On top of that, ads and banners with no reserved space, which push the content around.
The good news: the same actions that improve Core Web Vitals make the site simply more pleasant, and that translates into more enquiries and orders.
How to check it
Google's free PageSpeed Insights tool shows the score and specific suggestions. It is worth looking at "field" data (how real users see the site), not just the lab test.
We will improve the score step by step
We take the report, decide what gives the biggest effect for the least cost (most often images and cache), and roll out the changes, testing the site after each one.
