Shopify speed optimization services

How a speed engagement should run

1. 01

   Baseline

   Web performance reports and lab tests recorded for key templates.

   Output: Baseline figures

2. 02

   Diagnosis

   Apps, scripts, sections, fonts and images examined for their cost.

   Output: Causes ranked by impact

3. 03

   Changes in a duplicate

   Fixes made in a duplicate theme and previewed.

   Output: Tested changes

4. 04

   Publish and re-measure

   Published, then field data compared after enough visits.

   Output: Before-and-after report

Ask for causes, not just scores

A useful speed report explains why the store is slow: which app adds a large script to every page, which font files load before content, which section shifts the layout. A report that only lists a score and generic advice gives you nothing to act on. Before work starts, ask the provider to show you the main causes they have found on your store specifically.

Lab test scores vary between runs and devices. Field data from Shopify's reports, collected from real visits, is a steadier measure of the change.

Questions to ask a provider

Warning signs

• Guaranteed scores

  Lab scores vary, and no provider controls every factor.

• A speed app as the whole solution

  Often adds code rather than removing the cause.

• Removing features without asking

  Speed must not come at the cost of features your business relies on.

• Changes made directly on the live theme

  Leaves no safe way back if something breaks.

Decisions you will be asked to make

Keeping it fast

Stores slow down again as apps and sections are added. A good engagement ends with simple guidance: check the performance report after installing an app, remove apps you stop using and look for leftover code, and keep images and homepage sections in proportion. A periodic review, perhaps each quarter, catches drift before it becomes a problem.

Allow time for field data

Field data reflects real visits over a period, so improvements do not appear instantly. Stores with modest traffic may need longer before the reports show a clear change. A provider should explain this upfront and agree when the before-and-after comparison will be made, rather than declaring success from a single lab run on launch day.

What you should receive

At the end of the engagement you should have the baseline figures, the list of causes found, what was changed for each, anything deliberately left unchanged and why, and the after figures once field data has caught up. You should also have a note of any code removed or added, so future developers understand the current state of the theme.

This record makes later reviews quicker and helps you judge whether a new app is worth what it costs in speed.

Speed and features in balance

Faster is not always better if it means losing something customers value. Reviews, size guides and delivery estimates can all justify their weight. The aim is a store that is as fast as possible while keeping the features that help people buy, decided with you rather than for you.
