The problem
- 01
“Our Lighthouse score is 34 and nobody can tell us why.”
A speed score does not explain the cause. We investigate which issues affect shopping before choosing fixes.
- 02
“We installed a dozen apps and the site got slower with each one.”
Each app added its own scripts to every page, including the pages where it does nothing at all.
- 03
“Mobile takes forever but it looks fine on my laptop.”
You are testing on office wifi and a fast machine. Your customers are on mid-range phones and mobile networks.

Shopify Performance and Core Web Vitals Optimization FAQs
Will you get us a 100 Lighthouse score?
No. A perfect lab score can require removing useful features and does not reliably predict revenue. We target Core Web Vitals using real customer data, which reflects the shopping experience and contributes to Google rankings. A better score is a likely benefit, rather than the goal.
How much revenue will faster pages actually add?
We cannot estimate a gain before reviewing your store. Research links faster pages with better conversion, but the effect depends on your current speed, traffic and category. A store taking four seconds on mobile has more room to improve than one taking two seconds. The audit helps decide whether speed work is the best use of your budget.
Do we have to remove our apps?
Not necessarily. Some apps can load only on the pages that need them, preserving their features with less overhead. We recommend removal for unused apps, duplicate features or heavy scripts serving a limited purpose. We show you the performance cost of each app, and you decide.
Why do you need 28 days after the work is done?
Real visitor data uses a rolling 28-day window and needs enough traffic to be meaningful. It lets us report the same performance measures used for rankings and catch issues that appear under real traffic. Reporting immediately after release would rely on lab tests again.
Will this break during a theme update or app install?
Theme updates are fine because the work lives in your theme and is documented. App installs are the real risk, and that is why the report includes an evaluation checklist. Most performance regressions we see six months later trace to a single app added without anyone checking what it loads. If you want that watched continuously rather than checked once, it belongs in a managed services retainer.
Can you fix performance on a headless or custom front end?
Yes, as a separately priced project. Custom frontends need a review of unfamiliar code, build methods and rendering. The cause may require structural changes rather than tuning. We start with a paid audit to define the work.
