Shopify Apps: When They Kill Performance (and What to Do)

List every installed app and what customer-facing or admin value it provides. If you cannot name the metric it improves, it is a candidate for removal. Many performance problems are simply twenty apps each adding a script to the storefront.

For each app you keep, read how it injects into theme.liquid, product templates, and checkout extensibility. Some apps are necessary but should load only on specific templates. If the app does not support conditional loading, you may need a developer to isolate or replace it.

Use devtools and field tools to see which third-party requests block LCP. Prioritize removing or deferring the largest chain on your top money pages. Often one review or upsell app accounts for a disproportionate share of delay.

After removals, re-test conversion paths: cart, dynamic shipping, tax, and post-purchase flows. Performance work is only complete when revenue paths still work. Document the final app list and review it quarterly, because new apps creep back in under marketing pressure.

If you need expert help, ask for a written before/after report with template-level impact, not a generic "we optimized images" line. You want clarity on which apps stayed and why.
