Core Web Vitals
Google’s measures of how fast and stable a page loads from the point of view of the person in front of the screen. Free to check.
Why it matters when you read an offer
A useful measure because it does not depend on the provider’s opinion: anyone can check it for free in a minute. A slow site loses visitors before they have seen anything on it.
What it looks like in an offer
Guaranteed 100 speed score. The tool score is a consequence, not a goal: ask what will actually change on the site.
