Quick Fix: Properly set up preload with fetchpriority=high, or drop it completely.
The Problem:
Despite implementing various optimization techniques, the load delay for my website’s Largest Contentful Paint (LCP) remains high. I have added fetchpriority="high" and loading="eager" attributes to the image tag, preconnected and prefetched the image’s domain, and even preloaded the image using <link rel="preload". However, the load delay continues to be a bottleneck in improving my site’s LCP score. How can I identify and address the underlying cause of this high load delay?
The Solutions:
Solution 1: Review the HTML tags and attributes
– Modify `<link rel="preload">`:
Ensure the `<link rel="preload">` tag has the `fetchpriority="high"` attribute. This ensures the image is preloaded with high priority, allowing it to load faster.
– Remove unnecessary attributes:
Remove the `crossorigin` attribute from the `<link rel="preconnect">` tag and eliminate the `<link rel="dns-prefetch">` tag as it’s not needed with `preconnect`.
Solution 2: Consider Performance Implications of Third-Party Domains
– Hosting images on third-party domains:
Understand that hosting images on third-party domains can introduce some delay due to the initial connection setup cost. While image CDNs offer advantages, there may be a trade-off in terms of performance.
