A slow website can make it harder for a visitor to read, browse or complete a form. The cause may be a large image, a slow third-party script, an overloaded page or a hosting constraint. Measure first so you can fix the part that is actually slowing the site down.

Start with a repeatable measurement

Test important pages on mobile and desktop using PageSpeed Insights. It combines lab diagnostics with field data when enough real-user data is available, so the two views may not match. Google’s Core Web Vitals track loading, responsiveness and visual stability: good targets are LCP within 2.5 seconds, INP at or below 200 milliseconds and CLS at or below 0.1 for at least 75 percent of page visits. Read the current Core Web Vitals thresholds.

Reduce heavy images

Use an image sized for the space where it appears. Resize large photos before upload, use an efficient modern format where your site supports it and avoid loading a full-resolution image into a small card. Give the main page image priority and defer images that sit far below the first screen.

Trim scripts and page weight

Every plugin, tracking tag, chat widget, font and animation adds work. Remove features you no longer use, check whether a plugin loads assets on pages that do not need them, and avoid stacking several tools that perform the same job. Keep enough functionality for visitors, but do not make every page carry the entire site.

Check caching and server resources

Page caching can avoid repeating work for visitors who request the same page. A content delivery network can help serve static files closer to visitors. These tools need correct configuration, and logged-in, dynamic or checkout pages may need different rules. If a simple page is still slow after basic cleanup, ask the host to check account resource usage and server response time.

Re-test after each meaningful change

Keep a note of the page, device and test date. Change one group of things at a time, then retest. A synthetic score is a clue, not the full story: watch how quickly real visitors see the main content and whether they can use the page without delays or unexpected movement.
