free website check
Check your site in a minute
Google measures how fast your site loads on a phone, and we go over the technical points that matter to Google and to your visitors. Enter your web address, the result appears within a minute. We store nothing.
What the check looks at
The check loads your home page the way a browser does, follows any redirects and reads the html. It also looks for a robots.txt and a sitemap on your domain. At the same time Google PageSpeed loads your page the way an average phone on a slow 4G connection does. Each point gets fine, could be better or needs fixing. Google's score counts for 40 percent and the other points for 60 percent. A point that could be better counts for a third. When Google returns no measurement, the check shows the server's response time instead.
Google PageSpeed on mobile
Google considers a score under 90 too slow. It counts towards where you appear in the search results.
Largest block on screen (LCP)
Google wants the largest part of your page on screen within 2.5 seconds. Visitors on a phone who wait longer often leave.
Shifting content (CLS)
Text and buttons that still move while the page loads make visitors tap the wrong thing. Google wants a value under 0.1.
Responds to a tap (TBT)
While the phone runs scripts, the page ignores taps. Google wants that wait under 200 milliseconds.
Images and video
With modern formats such as WebP and images at the right size, this can usually stay under 0.5 MB.
JavaScript
Every script has to be loaded and run by the phone first. A lean site needs less than 0.3 MB.
Total weight on the first visit
On mobile data a visitor feels every megabyte. This is where most speed is to be gained.
Secure connection (https)
Without https the browser shows a warning and Google ranks you lower.
Server response time
Anything above a second is felt by the visitor. Often down to hosting or heavy plugins.
Page title
The title is the blue link in Google. Aim for 10 to 65 characters that say what you do and where.
Meta description
The text under your link in the search results. Google shows about 160 characters of it. Write that line yourself, or Google picks one from your page.
One main heading (h1)
Every page should have exactly one h1 that says what the page is about.
Works on mobile (viewport)
Without a viewport setting, a phone shows your site as a zoomed-out desktop.
Page language
Declare your site's language in the code. Screen readers and Google use it.
Preview when shared (Open Graph)
Without og tags, a link on WhatsApp or LinkedIn shows no image and a bare title.
Canonical link
Tells Google which version of a page is the real one and prevents duplicates.
Image alt texts
Describe what's in the photo. For visitors using a screen reader and for Google Images.
Favicon
The little icon in the browser tab. Small job, instantly more polished.
robots.txt
Tells search engines what they may visit. Belongs on every site.
Sitemap
A list of all your pages for Google. Without one, new pages get found more slowly.
What the check does not see
The check reads your home page only, the rest of the site stays out of view. The speed comes from one measurement on a simulated phone in a Google test environment. Real visitors can come out faster or slower, and a second run often gives a slightly different score. Whether your copy convinces and which search terms you rank for, it cannot tell you. That is what the website audit is for.
