- Oversized images are the most common cause of a slow page.
- Test on mobile first, using free tools from Google.
- Change one thing at a time and retest so you know what worked.
The Short Answer
Most slow websites are slow for the same few reasons: oversized images, too many scripts, cheap hosting and no caching. You can test your site for free in a few minutes, and fixing images alone often gives the biggest jump. Speed matters because visitors leave slow pages, and search engines pay attention to how a page feels to use.
What Core Web Vitals Measure
Google groups page experience into three measures. Largest Contentful Paint (LCP) is how long the main content takes to appear. Interaction to Next Paint (INP) is how quickly the page responds when someone taps or clicks. Cumulative Layout Shift (CLS) is how much the page jumps around while loading.
Google publishes target thresholds for each, and they can be updated, so check the current numbers in its documentation instead of trusting an old blog post.
How to Test for Free
Open PageSpeed Insights, paste your page address and read the mobile result first, since most Nigerian visitors browse on phones. Search Console also has a Core Web Vitals report that groups your pages by problem. Test your home page and your most visited article, not only one page.
The Fixes That Matter Most
Compress images. Use WebP, resize photos to the size they are shown and lazy-load images below the fold. A 3 MB photo on a mobile page is the most common problem.
Reduce scripts. Every chat widget, tracker and font adds weight. Remove the ones you do not use, and load the rest with async or defer.
Set image sizes. Give each image a width and height so the layout does not jump while it loads.
Use caching and compression. Ask your host to enable Gzip or Brotli and browser caching.
Check your hosting. If the server itself is slow to respond, no code change will rescue the page. Consider a host with servers close to your audience.
Fonts and Third-Party Tools
Limit yourself to one or two font families and only the weights you use. Be careful with embeds such as videos and maps. Show a thumbnail first and load the full embed only after a click.
Track Progress
Change one thing at a time and retest, so you know what helped. Keep a simple note of your score before and after, and recheck monthly after you add new pages.
Action Checklist

- Compress and convert large images to WebP
- Add width and height to every image
- Remove unused plugins, widgets and scripts
