Core Web Vitals: how site speed affects your rankings and sales
Google measures how fast and stable your site feels. those scores affect both your rankings and your conversion rate.
Core Web Vitals are Google's way of measuring how fast and stable your website feels to a real person using it. They're not an abstract technical score for developers to admire. they directly affect your search rankings and, just as importantly, how many of your visitors stick around long enough to become customers. A slow, janky site loses you traffic and sales at the same time, which is why this is one of the highest-leverage things to get right.
The three metrics that matter
There are three core measurements. LCP (Largest Contentful Paint) measures how quickly the main content of a page becomes visible. ideally under 2.5 seconds. INP (Interaction to Next Paint) measures how fast the page responds when someone taps a button or link, so it should feel instant, not laggy. CLS (Cumulative Layout Shift) measures how much the page jumps around as it loads. you've felt this when you go to tap something and it shifts at the last second. Google wants all three to feel fast and stable, and so do your visitors.
Why most websites fail them
When a real site scores badly, the causes are almost always the same, unglamorous handful. Oversized, uncompressed images are the biggest culprit. then too many third-party scripts (chat widgets, trackers, ad pixels), heavy page builders and themes that load far more code than the page needs, and cheap, overloaded hosting that's slow to respond in the first place. The good news is that every one of these is a known, fixable problem. there's rarely anything mysterious about a slow site.
How we hit 95+ consistently
We build with React and Next.js, which lets us statically render pages and serve them from an edge cache close to each user, so the first load is genuinely fast. On top of that we compress and lazy-load images so they never block the page, strip out unused scripts, and host on fast infrastructure with a CDN. The result is sub-second loads and Lighthouse performance scores of 95 and above, on mobile, not just on a developer's fast laptop.
What good speed actually does for your business
Faster sites earn it back in three ways. They tend to rank higher, because speed is a confirmed ranking factor and a fast site is also crawled more efficiently. They convert more of the same traffic, because fewer impatient visitors bounce before the page loads. And they make every other marketing rupee work harder, since the ads and SEO driving traffic now land on a page that doesn't leak visitors. Speed isn't a vanity metric. it's revenue. If your current site feels sluggish, we can audit and fix it.
