Website speed is an SEO problem, not just a UX one
Site speed affects rankings directly, and affects them again indirectly through visitor behaviour. Here's how the two connect.
Page speed shows up in SEO conversations constantly, but it’s worth being specific about why it matters, because it’s actually two separate effects stacked on top of each other.
The direct effect
Google has used page experience signals, including load speed, as a ranking factor for years. A slow site is working against its own rankings before content or backlinks even enter the conversation.
The indirect effect
Slow sites lose visitors before the page finishes loading. Every visitor who leaves early is a signal to search engines that the page didn’t satisfy the search, and a visitor who never saw your offer was never going to enquire anyway.
What usually causes slow sites
- Bloated page builders and plugins: common on older WordPress sites carrying years of accumulated add-ons.
- Unoptimised images: often the single biggest fix available on an older site.
- Render-blocking scripts: third-party trackers and widgets loading before the actual content does.
- Shared, generic hosting: infrastructure not configured for the platform actually running on it.
Where to start
Run your homepage through a speed testing tool and look at what’s actually large or blocking. Usually it’s a small number of specific culprits, not a fundamental rebuild. Though sometimes, particularly on older sites, a rebuild genuinely is the faster path to a fast site.
