Website speed for local businesses: Core Web Vitals in plain English

Most people find a local business on their phone, often in a hurry. A page that is slow to show up, ignores taps or jumps around as it loads makes that harder. Google measures these three problems with what it calls Core Web Vitals. Here is what they are, the targets Google publishes, and how to check your own site.

The three measurements

Google’s Search Central documentation describes each one in a few words. The targets are the ones Google recommends.

Largest Contentful Paint (LCP): loading
How long it takes for the main content of the page to appear. Google says to “strive to have LCP occur within the first 2.5 seconds” of the page starting to load.
Interaction to Next Paint (INP): responsiveness
How quickly the page reacts when someone taps a button, opens a menu or types in a form. Google says to “strive to have an INP of less than 200 milliseconds.”
Cumulative Layout Shift (CLS): visual stability
How much the page moves around while it loads, such as a button sliding away just as someone goes to tap it. Google says to “strive to have a CLS score of less than 0.1.”

Good, needs improvement, poor

Google’s web.dev article on how the thresholds were chosen lists a “good” and a “poor” level for each measurement. Loading is good at 2.5 seconds or less and poor above 4 seconds. Responsiveness is good at 200 milliseconds or less and poor above 500 milliseconds. Stability is good at 0.1 or less and poor above 0.25. Anything in between needs improvement.

The levels are judged across real visits, not a single test. In Google’s words, “to classify the overall performance of a page or site, we use the 75th percentile value of all page views.” Put simply, a page passes a measurement when at least three out of four visits meet the good level. The same thresholds apply on phones and computers, even though, as the article notes, the two “typically have very different characteristics as to device capabilities and network reliability.”

What it means for search, and what it doesn’t

Google’s page experience documentation says plainly that “Core Web Vitals are used by our ranking systems,” and its Core Web Vitals page says: “We highly recommend site owners achieve good Core Web Vitals for success with Search.”

The same documentation is just as clear about the limits. Google says its systems always seek to show the most relevant content, even when the page experience is poor, and that good results in its reports don’t guarantee your pages will rank at the top. In other words, speed doesn’t make up for a page that doesn’t answer what the customer is looking for. Google says a great page experience helps most when many pages are similarly helpful for a search.

Google’s page experience self-assessment also asks about more than speed: whether pages are served securely (HTTPS), display well on mobile devices, avoid an excessive amount of ads that get in the way of the main content, and avoid intrusive interstitials (pop-ups that cover the page).

How to check your own site for free

  1. Run PageSpeed Insights

    Enter your home page address at pagespeed.web.dev. Google’s documentation says PageSpeed Insights “provides both lab and field data about a page.”

  2. Read the real-visitor section first

    Field data reflects real visitors over “the previous 28-day collection period.” Lab data comes from a single simulated device and network, which Google says is useful for finding problems but may not match what customers see.

  3. Don’t worry if there’s no real-visitor data

    A small local site may not have enough visits to show field data. PageSpeed Insights then falls back to your whole site, and if that isn’t enough either, it shows only the lab test. Use the lab results as a guide in that case.

  4. Check every important page, on mobile

    Test the pages customers land on: the home page, each service page and the contact or booking page. The mobile result is the one most local customers will feel.

  5. Use Search Console once it’s set up

    Google recommends the Core Web Vitals report in Search Console, which shows how your pages perform. It needs your site to be verified in Search Console first.

Common causes on small business sites

These are general patterns rather than findings from the sources above. A site check shows which ones apply to yours.

Very large photos
A full-size photo straight from a camera or phone can take seconds to load on a mobile connection. Resized, compressed images usually fix the loading measurement.
Too many add-ons
Chat widgets, sliders, trackers and plugins each add code the phone has to download and run, which slows loading and responsiveness.
Images and banners without reserved space
When a photo, ad or cookie banner appears without space set aside for it, everything below it jumps down, which is what the stability measurement counts.
Slow or distant hosting
Cheap shared hosting can take a long time to send the first byte of the page, before anything else can happen.

Common questions

Will a faster website rank higher on Google?

Google says Core Web Vitals are used by its ranking systems, but it also says it always seeks to show the most relevant content and that good scores don’t guarantee a top ranking. Speed helps most when competing pages are similarly useful.

What are good Core Web Vitals scores?

Google’s targets are the main content showing within 2.5 seconds, a reaction to taps within 200 milliseconds, and a layout shift score below 0.1, met by at least three out of four visits.

Why does PageSpeed Insights show no real-user data for my site?

Field data needs enough real visits over the previous 28 days. Small sites often don’t have enough, so PageSpeed Insights shows only its lab test.
