Run a speed audit on my store and fix the biggest issues.

Run a speed audit on my store and fix the biggest issues you find. Start with the homepage and my best-selling product pages.
- One request covers the loop: audit, fix, re-test.
- Fixes land in a draft theme — your live store is untouched until you publish.
- Covers the usual culprits: LCP images, render-blocking scripts, layout shift, heavy apps.
- Flags third-party apps when they're the bottleneck Fudge can't fix directly.
What you're trying to do
Slow pages lose shoppers before they see your products, and Core Web Vitals feed Google's ranking. Audit tools stop at the diagnosis and hand you a to-do list. The optimization loop closes it: find the failures, write the fixes into the theme, re-test to confirm the score actually moved. Most stores are two or three fixes away from 'good' — the work is finding which ones.
Things to watch out for
- Fixes without re-tests — a fix that isn't re-measured is a guess. Fudge re-runs the audit on the draft.
- Chasing the score — the goal is faster pages for real shoppers, so field data beats lab numbers where available.
- App bloat — when the bottleneck is a third-party app's script, the honest fix is removal or replacement, and Fudge says so.
- Live-store risk — Fudge handles this: every fix lands in a draft you preview before publishing.
How Fudge does it
Fudge audits your pages, traces each failing metric to its cause, and writes the fixes into a draft theme — your live store stays untouched. It then re-tests the draft to confirm the improvement before you're asked to review. You preview, approve, and publish; every published change stays undoable.
When the audit report isn’t the point
Every store owner has run a speed test and closed the tab with a list of findings and no idea which matter. The diagnosis was never the hard part — the hard part is knowing which three of the forty findings actually move the needle, writing the theme changes, and proving the score improved afterward.
When this is worth doing
Before high-traffic moments, after installing apps or changing themes, and any time mobile feels sluggish — mobile is where most failures live and where most of your traffic is. If your product pages load slowly, you’re paying for ads that time out.
What makes speed work stick
- Prioritized by impact — fix the LCP image before the 40ms script. Two or three changes usually carry the score.
- Fixes in a draft — theme changes are previewed, not pushed live on faith.
- A re-test — the loop isn’t closed until the improvement is measured on the fixed version.
- Honest app verdicts — when an app’s script is the bottleneck, the fix is a decision about the app, not more optimization around it.
Common mistakes to avoid
The biggest mistake is optimizing around a problem that should be removed. A heavy app costs you on every page load; deferring its script softens the blow but the honest answer is often uninstalling it.
The second mistake is measuring once. Performance regresses silently — new apps, bigger images, added sections. Re-run after significant changes.
Pair this with the mobile UX audit and the SEO audit — speed, usability, and ranking failures often share root causes.
