Website performance
Theme weight, images, third-party scripts, and Core Web Vitals—treated as conversion work, not a Lighthouse vanity score.
Zqdo improves website and Shopify performance when slow pages are costing you bounce, ad efficiency, or rankings. We find the actual bottleneck, then ship the fix.
The service
Slow pages tax every visitor. On mobile, that tax is higher. Paid traffic gets more expensive when landing pages stall. Organic pages bounce before the offer is even read.
On Tennis Express we treated Core Web Vitals, third-party scripts, and template weight as revenue work—not a Lighthouse trophy. The same triage shows up on high-traffic Shopify brands like Tushbaby and American Barbell when apps and theme debt start costing conversion.
On Shopify the usual causes are heavy themes, overlapping apps, oversized media, and Liquid that does too much work. On other CMS platforms it is often plugins, page-builder bloat, and unoptimized images.
Who it’s for
A fit when speed is a known complaint or a measured conversion drag.
Problems we solve
If shoppers mention slowness unprompted, you already have a conversion leak.
We profile LCP, INP, and the request waterfall on the templates that make money.
Each script has to earn its keep. Many do not.
Modern formats, sizing, and lazy-loading patterns are implemented in the theme or CMS.
We leave a maintainable setup so the next app install does not erase the gains.
What’s included
Diagnosis first. Then a short list of changes that move real metrics.
Lab and field signals, template-level bottlenecks, app/script inventory.
Render path, CSS/JS, Liquid or builder cleanup.
Images, video, and font loading that protect LCP.
We capture a baseline so you can see whether the work landed.
Process
Fix the largest constraint first. Do not boil the ocean.
01
Measure the templates that matter on mobile.
02
Separate theme, apps, media, and hosting issues.
03
Implement the highest-impact fixes.

Often yes, especially on mobile. Performance is one of the few changes that improves the experience for every visitor. It is not a substitute for a weak offer.
Usually. Many stores need an audit and a focused implementation, not a new theme. Sometimes the theme itself is the constraint, and we will say so.
The guides teach the levers. This service is Zqdo doing the diagnosis and the implementation on your storefront or site.
