To improve website speed, test your page at PageSpeed Insights, look first at how long the main content takes to appear on a phone, and fix the largest causes: oversized images, slow hosting, heavy scripts and too many fonts. Small sites usually get the largest gains from images.
Do not chase a perfect score. Chase a page that appears quickly and stays still on a normal phone.
Step 1: Run the test
Go to PageSpeed Insights, enter your address and open the Mobile tab. Scores move a little between runs, so test two or three times before you decide anything changed.
Step 2: Understand the three numbers that matter
Google's Core Web Vitals measure the experience in three ways:
Step 3: Fix in this order
Images
Do not upload a 5 MB camera photo for a space that is 800 pixels wide. Use the AVIF or WebP formats, and create several sizes so a phone downloads a small version. Load images lower down the page only when the visitor scrolls near them.
The first image
Often the largest item on the first screen is an image, and that image usually decides your LCP. Tell the browser about it early, and never make it wait for other files to load first.
Scripts and add-ons
Each chat widget, slider and tracking tag adds work for the phone. Remove what you do not use. On WordPress, deactivate and delete unused plugins.
Fonts
Use one or two font families, host them on your own site, and include only the characters and weights you use.
Hosting and caching
If the server itself responds slowly, no design fix will help much. Use caching, and a content delivery network if your visitors are spread out.
A real example: our own website
In October 2026 we tuned this website and recorded the result in PageSpeed Insights, on a phone test, with one run each:
The work was not exotic. We told the browser to fetch the first image before the fonts, cut a video poster from 109 KB to 10 KB, and trimmed one font file from 40 KB to 13 KB by removing characters we did not use.

Common questions
Does speed help Google rankings?
Good page experience supports your other SEO work, but useful content matters more. A fast page will not outrank a far more helpful one on speed alone.
What is a good PageSpeed score?
Google treats 90 and above as good. Aim for it, but focus on the three measures above, since those describe what visitors actually feel.
Why does my score change every time?
Each test runs under slightly different network and device conditions. Compare several runs rather than a single number.
