Trouble with LCP Score in Shopify Public App

Shopify Apps
1

Hello Shopify Community,

I’m currently facing an issue with the LCP (Largest Contentful Paint) score for my Shopify app. Despite our server responding in about 200ms and ensuring that the app is set up correctly, the LCP score remains consistently above 3-4 seconds. This happens regardless of the changes I make.

Here are some details:

  • Server Response Time: 200ms
  • LCP Score: consistently above 3-4 seconds
  • Observations: The score fluctuates frequently even with minimal changes made.

I would appreciate any insights, suggestions, or troubleshooting steps you could recommend to help improve the LCP score. Are there specific optimizations I should consider or common pitfalls that could lead to this issue?

Thank you for your assistance!

Best,
Er Sanjay

Try Cloudflare for Caching and use its RUM for identifying the regional traffic and corresponding LCP. Most of the time, high TTFB is the main cause for LCP hikes.
