Page Speed Optimisation

The most common mistake in a conversation about speed is guessing. A site is not fast because it feels fast to you. A measurement shows what happens on a visitor phone, not on the connection in your office.

We always start by measuring. Improving a site without knowing what slows it down produces work that feels productive and changes nothing.

What We Look At

Image weight

This is the most common cause we see. An image displayed 400 pixels wide on a phone is downloaded at its original 3000 pixels. Generating correctly sized versions alone makes a visible difference on most sites.

JavaScript weight

We measure how much of the downloaded code actually runs. A library that never executes still costs download time and processing time on the device.

Content that jumps

Text and buttons shifting while a page loads is more than annoying, it is a defect search engines measure. Reserving space for images and late loading sections puts a stop to it.

Third party scripts

Analytics, chat widgets and advertising pixels affect your speed as much as your own code does. We decide together which ones are genuinely needed and when they should load.

How We Work

  • We take before and after measurements under the same conditions and show them side by side.
  • We treat the mobile measurement as the real one, because most visitors are on a phone.
  • We do not suggest breaking the design to gain speed. If that trade off comes up we discuss it separately.
  • We report the improvement per URL, so you can see where it landed.

Projects Where We Did This

Frequently Asked Questions

It does, though not on its own. A thin page does not rank because it loads quickly. Between two pages of similar quality the faster one wins, and more importantly a slow page loses the visitor before it even appears.

No. The score is a diagnostic, not a target. The compromises required to reach 100 sometimes hurt the experience. What we watch is the measured experience of real visitors.

Partly. Image derivatives, cache settings and removing unused scripts can be done on most sites without touching the design. If the structure itself is the bottleneck, a deeper change is needed.
