This is the checklist version. If you do not know why the store feels slow, read why is my Shopify store slow first. If you want the reasoning behind the order, read how to speed up a Shopify store. Use this page when you already know you will work through items.

Measure three mobile pages. Remove unused apps and duplicate widgets. Compress the first image on each of those pages. Then turn off unused theme features. Only then edit Liquid. Do not install a speed optimiser as step one.
The checklist
| # | Check | Done when |
|---|---|---|
| 01 | Pick URLs | Homepage, one collection, one product, cart if you can |
| 02 | Measure on mobile | Lab report plus a real phone walk |
| 03 | Write down LCP element | You know which image or block is the large paint |
| 04 | App uninstalls | Unused apps gone, not just hidden |
| 05 | Duplicate widgets | One reviews tool, one popup, one chat |
| 06 | Hero media | First image compressed, not a video unless you need it |
| 07 | Product gallery | First image eager, extra shots can wait |
| 08 | Fonts | Two families or fewer, no extra weights you do not use |
| 09 | Theme sections | Unused sliders and marquees off on the homepage |
| 10 | App embeds | Theme settings: unused embeds disabled |
| 11 | Tags and pixels | Marketing tags you cannot name are removed |
| 12 | Layout shift | Announcement, reviews and sticky bars do not jump add to cart |
| 13 | Re-measure | Same three URLs, same device class |
| 14 | Theme code | Only if 01 to 13 still leave a real problem |

Notes that stop people skipping steps
Step 02 can use our page speed test or PageSpeed Insights. Lab scores are clues. A mid-range Android in a lift is the real test.
Steps 04 and 05 are where most stores get their first win. We wrote a longer piece on apps that slow a store. For Core Web Vitals names, see Core Web Vitals without guessing.
Do not host the Shopify shop on Hostinger to “make it faster”. Shopify already hosts the shop. Hosting advice is for company sites in what web hosting is.
NP SoftTech can audit apps and templates, then change what loads. Share the store URL and the worst page on a phone.
