FAQ
My store looks fine on desktop but feels off on mobile. Is it worth fixing if sales are still coming in?
Over 70% of Shopify traffic is mobile. Buyers leaving because of a broken mobile layout never tell you why. You only see the sales that happened, not the ones lost silently. Fix it before it compounds.
I uninstalled an app weeks ago but my store still feels slow and some sections look wrong. Could that be related?
Yes. Uninstalling an app does not remove the code it left in your theme. Dead scripts and orphaned CSS keep loading on every page, slowing your store and causing visual conflicts that have nothing to do with your current setup.
I changed my theme and now my checkout feels broken. Can a theme change affect checkout?
Yes. Theme changes affect cart drawers, payment button display, shipping rate visibility and discount fields. A new theme can silently break your buying flow without any error message, buyers just abandon.
Someone added custom CSS to my store and now parts look wrong. Can it be fixed without rebuilding everything?
Almost always yes. Bad CSS rarely destroys the underlying theme, it just overrides it incorrectly. I isolate what's conflicting and rewrite only what needs changing without touching what was already working.
Does fixing theme bugs actually improve my Google ranking?
Directly. Google measures layout stability, load speed and interaction response as ranking signals. A broken layout fails Core Web Vitals. Leftover app scripts increase load time. Fixing theme-level issues improves SEO and buyer experience at the same time.
I keep getting a low PageSpeed score but don't know what's causing it. Can you identify it specifically?
Yes. Low scores are rarely one thing ; usually uncompressed images, render-blocking scripts, unused CSS from old apps and theme animations combined. I diagnose each factor by weight and fix what lives inside the theme layer.
I keep having theme issues every time I update or install something. Is there a way to prevent this?
Yes. I duplicate your live theme before any changes, creating a safe testing environment. I also show you the correct order to install apps and flag which app types historically cause the most theme conflicts.
