Page speed affects both how visitors feel about your site and how Google ranks it. The good news: most WordPress speed problems come down to a short list of usual suspects, and none require a developer to fix.
1. Oversized images
A single 4MB photo straight from a phone camera can double your page load time. Compress images before upload, or install a plugin like ShortPixel or Imagify that compresses automatically.
2. Too many plugins
Every active plugin adds code that has to load on every page view. Go to Plugins → Installed Plugins and deactivate anything you don't actually use — old contact form builders and abandoned page builders are common culprits.
3. No caching
Without a caching plugin, WordPress rebuilds each page from scratch on every visit. A plugin like WP Super Cache or LiteSpeed Cache stores a ready-made version of your pages, cutting load times dramatically.
Key takeaway: Caching alone typically cuts page load time by 40–60% on a default WordPress install.
4. A bloated theme
Heavy "all-in-one" themes with dozens of built-in features you never use still load that code on every page. Lightweight themes like GeneratePress or Astra are worth the switch.
5. Slow hosting
No amount of optimisation fixes an underpowered server. If your host is overselling shared hosting slots, look for a provider offering NVMe SSD storage and LiteSpeed web servers, both of which are significantly faster than older HDD/Apache setups.
6. Unoptimised database
Years of post revisions, spam comments, and transient data bloat your database. A plugin like WP-Optimize can clean this up in one pass.
7. No content delivery network (CDN)
If your visitors are spread across Ghana and beyond, a CDN caches your static files (images, CSS, JS) on servers closer to each visitor, shaving critical milliseconds off every load.
