I will optimize shopify speed and core web vitals
Yingjie Qi
About this gig
I will optimize your Shopify storefront for faster loading, better mobile performance, and healthier Core Web Vitals without breaking your theme or customer experience.
I can help identify and fix high-impact performance bottlenecks in Liquid, JavaScript, CSS, images, third-party scripts, and Shopify apps. I can also review lazy loading, render-blocking assets, duplicate code, app bloat, and theme behavior across key storefront pages.
My process:
1. Audit the current Shopify storefront and performance signals
2. Identify the highest-impact theme, app, script and asset issues
3. Implement eligible fixes in a duplicate theme or safe test environment
4. Test key desktop and mobile pages after changes
5. Provide a clear summary of what changed and any remaining platform or app limitations
Please message me before ordering if your store uses a heavily customized theme or many third-party apps. I do not guarantee a specific PageSpeed score or Core Web Vitals pass because results can also depend on Shopify infrastructure, apps, third-party services, device and network conditions.
Respect third-party rights
Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.

FAQ
Do you guarantee a specific PageSpeed score or Core Web Vitals pass?
No. I will fix eligible Shopify performance issues, but final scores can also depend on Shopify infrastructure, apps, third-party scripts, device and network conditions.
Will you work safely without affecting my live Shopify store?
Yes. I normally work in a duplicate theme or safe test environment, verify the changes first, and avoid unnecessary edits to the live storefront.
What access do you need to optimize my Shopify store?
Usually Shopify collaborator or admin access is enough. If an app is part of the performance issue, app access may also be needed. I do not need your password when official permissions can be granted.
Can you optimize a store with many Shopify apps or third-party scripts?
Yes. I can audit their performance impact and optimize eligible theme or loading behavior. Some vendor-controlled code may have limits, which I will document clearly.
