Why your website is slow — and what we do about it

Speed isn't a vanity metric. A slow site loses customers and rankings. The good news: the usual culprits are well understood and fixable.

When people say their site “feels slow,” it's rarely one big problem. It's usually a stack of small ones. Here are the ones we run into most.

Oversized images

By far the most common issue. A photo exported straight from a camera or design tool can be several megabytes. Resized and compressed properly, the same image can look identical at a tenth of the size.

Too many third-party scripts

Chat widgets, analytics, ad pixels, and marketing tags all add up. Each one is code loaded from someone else's server, and any one of them can drag the whole page down.

Doing work on every visit

If a page rebuilds itself from scratch for every visitor when the content rarely changes, that's wasted time. Caching and pre-rendering fix most of this.

How we approach it

  • Measure first with real tools, not guesswork
  • Fix the biggest offenders before the small ones
  • Set a performance budget so it doesn't creep back

A faster site is one of the highest-return improvements you can make. It helps conversions, SEO, and the plain impression that your business is well run.
