Hello @weebySagar , Sudden spikes in the LCP are dangerous for the site's performance. If you make any change in
Images like converting the image into non-WebP format or an unoptimized format that is the main cause for a sudden hike in the LCP, so make sure if you made any changes in the website, especially regarding images, you should try to check that any action is performed or not.
If you do not perform any of these actions, then you should follow the suggestions below to optimize LCP -
Optimize Critical CSS
Loading unnecessary CSS files or too many styles can delay the rendering of above-the-fold content. Extract and inline critical CSS to reduce the time it takes for the page to be displayed. First, try to do inline critical CSS by including the styles required for above-the-fold content directly in the <head> tag to prevent a delay in rendering. Additionally, you can do minification of CSS
Example -
Before Minification
body {
font-family: Arial, sans-serif;
background-color: #f4f4f4;
color: #333;
line-height: 1.6;
}
After Minification
body{font-family:Arial,sans-serif;background-color:#f4f4f4;color:#333;line-height:1.6}
Use Efficient Server Response Times (Reduce TTFB)
A slow TTFB can delay the rendering of the largest contentful element. Optimize your server to respond quickly. You can try delivering content closer to the user by using a Content Delivery Network (CDN), which reduces latency. Additionally, reduce the number of API calls needed for the LCP element and ensure API responses are fast.
