Why Website Speed Matters for SEO (And How to Fix It)

Website speed isn’t just a nice-to-have — it’s a confirmed Google ranking factor, and it directly affects how many visitors stick around long enough to become customers. A slow site quietly costs you both traffic and conversions, often without you realising it’s happening.

How Page Speed Affects Rankings

Google uses a set of metrics called Core Web Vitals — covering loading speed, interactivity, and visual stability — as part of how it ranks pages. Sites that load slowly or shift content around as they load are ranked lower than fast, stable alternatives, all else being equal.

What’s Slowing Your Site Down

The most common causes of a slow website are:

• Unoptimised images — large photo files that haven’t been compressed
• Too many plugins or scripts loading on every page
• Poor quality hosting that can’t handle traffic efficiently
• Render-blocking resources like fonts and scripts that load before the page can display

Quick Wins to Improve Speed

Compressing and correctly sizing images is usually the single biggest improvement you can make. Beyond that, using a caching plugin, minifying CSS and JavaScript, lazy-loading images below the fold, and choosing quality hosting all add up to meaningfully faster load times.

Tools to Test Your Site Speed

Google’s own PageSpeed Insights tool is the best place to start — it’s free and shows you exactly what’s slowing your site down on both mobile and desktop, along with specific recommendations.
