It is 6pm, a customer taps your homepage on patchy 4G, and the WordPress CDN you pay for is meant to make the page snap open before they ring the next plumber. Sometimes it does. Sometimes a static site would have loaded twice as fast.
Run the speed test yourself this week
An hour on your busiest page settles it.
- Run the page that earns you money, usually the homepage, through a mobile test from a UK server.
- Note one metric first: Largest Contentful Paint on a mid-range phone, the moment the page looks ready.
- Turn the WordPress CDN on properly, caching the HTML at the edge, not just images.
- Retest, then compare against a plain static version of the same page. Our breakdown of static build and deploy times in the UK shows how quick that side ships.
Where a WordPress CDN quietly loses
A CDN wins when the setup is clean, but it falls over three ways you only see when you measure.
- It caches the pictures, not the page. Many plugins push images to the edge but rebuild the HTML on every visit, so the part the customer waits on still runs on your server.
- It cannot outrun plugin bloat. Twenty plugins and a page builder add render-blocking scripts no CDN can cancel. That is often where a static build wins outright.
- It hides a slow host. A poor first-byte time gets masked for repeat visitors, worse again for shops, as we cover in running a shop on static versus WordPress.
So which one should you pick
A few pages that rarely change: a static build with a CDN in front is faster and cheaper. Weekly posts, bookings or daily edits by non-technical staff: WordPress plus a well-set-up CDN earns its keep. The full trade-off sits in our pillar comparison of WordPress versus static site hosting for UK SMBs. Rather have it handled for one price, see our pricing or how we run hosting and support.
The honest answer
Nobody on TikTok bothers with real benchmarks, but they beat opinions. WordPress with a CDN is not a viral topic because tuning cache rules is unglamorous, and unglamorous is where the SEO and conversion wins still live in 2025. A page that opens in under two seconds converts better than one that limps in at five.
The research backs this up. Moz Local Search Ranking Factors and Backlinko CTR Stats both publish UK-applicable numbers that line up with what the speed test shows. Skim either for the raw figures.
