WordPress is not slow. The way most contractor sites are built on it is: a purchased theme that ships every feature it has, a drag-and-drop page builder on top, fifteen plugins, and full-size photos. Each layer adds code the phone must download and run before it can draw your headline.
Strip the layers and WordPress can be quick; most owners never get the chance, because the person who built it has moved on.
Where the seconds go
- The theme. Multi-purpose themes are sold on demos with sliders, portfolios, shops and animations. All of that loads on your page whether you use it or not.
- The page builder. Elementor, Divi, WPBakery and the like let a non-developer lay out a page, and pay for it with large scripts and styles on every load. The builder is the single biggest cause of slow WordPress contractor sites we audit.
- Plugins. A form, a review feed, a slider, a chat bubble, two SEO plugins, a cache plugin to fix the others. Each is a request or ten.
- Images. Camera-size photos in a 390-pixel column. See the speed guide.
- Hosting. Shared hosting adds a second or two of server time on a busy day. Usually the smallest piece.
Can it be fixed in place?
Sometimes. Resizing images, removing dead plugins, a decent cache and a better host can take a 7-second WordPress site to 4. Getting under Google's 2.5-second line on a builder theme is rare, because the builder's own code is the floor. That is why our rebuilds are not WordPress: they are plain, hand-written pages with the styles inside them, one font and no plugin layer, which is how the demo sites land under a second on the phone test. Check one with the 60-second test.
What you lose by leaving WordPress
The admin screen where you edited pages yourself, and the plugin ecosystem. In our experience most contractors edited the site twice a year and the plugins were the problem. Edits go through us and are included in the fee; and you own the code either way, as the ownership answer explains.
My web person says a cache plugin will fix it.
It will help, mostly for the second visit. The homeowner's first visit still downloads the builder, the theme and the images. Run the 60-second test before and after and read the seconds, not the score.
What about Wix and Squarespace?
Same shape: a general-purpose builder whose code you cannot remove. They are tidier than a neglected WordPress install and slower than a plain page, and you own nothing on them. Test any site you are considering on the Mobile tab before you commit.
