A healthy website loads quickly, works on every phone, keeps visitors safe, and shows up when customers search. This guide explains what good looks like and walks you through checking your own site in about 30 minutes, using free tools.
A website can look good and still lose customers. These six things are what separate a site that works for your business from one that only sits there.
The main content appears within about 2.5 seconds on a phone, and the page responds straight away when someone taps a button or a menu.
Text is readable without zooming, buttons are easy to tap, and nothing runs off the side of the screen on a phone or tablet.
Every page loads over HTTPS with a valid certificate, the software behind it is kept up to date, and browsers show no security warnings.
Pages are indexed, each has a clear title and description, and a sitemap tells search engines what exists.
Text has enough contrast, images have descriptions, and the site can be used with a keyboard or a screen reader.
Contact details are easy to find, forms deliver to your inbox, and no link leads to a dead end.
Google measures real-world page experience with three numbers called Core Web Vitals. These are the published targets, and the free tools in this guide report all three.
How long the biggest thing on the screen, usually the main image or headline, takes to appear.
How quickly the page reacts after a tap, click or key press.
How much the page jumps around while it loads. Lower is better.

How to read your results
Judge your site on its mobile results first, since that is where most small-business sites are slowest. Google counts a page as passing when at least 75% of real visits meet the Good target for all three Core Web Vitals. A new or low-traffic site may show no real-visitor data yet. In that case, use the lab scores as your guide and check again in a few months.
Work through these eight checks in order and note anything that fails. You will finish with a clear list of what to fix.
Google's PageSpeed Insights tests any public page and reports the Core Web Vitals above.
A tool cannot tell you how your site feels to use. Turn off Wi-Fi so you are on mobile data, then visit your site the way a customer would.
You do not need a drawer full of devices. Chrome has a built-in preview for phones and tablets.
Visitors and search engines both expect a secure connection. Browsers warn people away from sites that do not have one.
A fast site is no use if it is missing from search results.
These are the details search engines read to understand each page.
An accessible site works for people using screen readers, keyboards or larger text, and it tends to be easier for everyone else too. The common standard is WCAG 2.2 Level AA.
Nothing loses an enquiry faster than a button that does nothing.

It is a review of how well your site performs in the areas that affect visitors and search engines: speed, mobile usability, security, search visibility, accessibility and working links and forms. You can do a basic one yourself with free tools.
Aim for the main content to appear within 2.5 seconds on a phone. That is Google's Good target for Largest Contentful Paint. The page should also respond to taps within 200 milliseconds.
A Performance score of 90 or higher is rated Good, 50 to 89 needs improvement, and below 50 is Poor. The score is a lab estimate, so treat the Core Web Vitals assessment, which uses real visits, as the more important result.
Yes, though it is one factor among many. Google uses page experience signals, including Core Web Vitals, in ranking. Useful, relevant content still matters most, and speed helps when pages are otherwise similar.
Google retired its standalone Mobile-Friendly Test in December 2023. Use the Mobile tab in PageSpeed Insights, the device preview in Chrome, and your own phone, as described in steps 1 to 3.
Lab tests are affected by server load, network conditions and third-party scripts, so a swing of a few points is normal. Run the test three times and use the middle result.
A quick form-and-links check each month and a full check every three months suits most small-business sites. Always re-test after a redesign or after adding new features.
Start with anything that blocks customers: security warnings, broken forms and pages that are unusable on a phone. Then work on speed. If the fixes are beyond what your website platform lets you change, it may be time for professional help or a rebuild.
