Improve LCP in Divi
### 1. **Optimize the Background Image**
– **Use a WebP format**: Convert the background image to WebP format, which is highly compressed and faster to load.
– **Lazy-load the image**: Ensure that the background image is lazy-loaded, but if it's in the viewport on initial load, lazy-loading may not be necessary. Instead, make sure it loads efficiently.
– **Serve appropriate size**: Use the appropriate image size for different screen resolutions to avoid loading unnecessarily large images.
– **Use a CDN**: Serve the background image via a Content Delivery Network (CDN) for faster delivery.
### 2. **Preload the Critical Background Image**
– Add a “ tag in the “ of your HTML to prioritize loading of the background image for faster LCP.
### 3. **Reduce Render-blocking Resources**
– **Minimize CSS and JavaScript**: Defer non-critical JavaScript and reduce unused CSS that might be blocking the rendering of the content.
– **Inline Critical CSS**: Inline the CSS necessary for above-the-fold content to load faster.
### 4. **Font Optimization**
– **Preload fonts**: Preload critical fonts used in the text block to avoid delays in rendering the text.
– **Use font-display: swap**: Ensure that the text block renders even if the custom font hasn't loaded yet by using `font-display: swap` in your CSS.
### 5. **Enable Caching**
– Enable caching for static resources like the background image, CSS, and JavaScript. This allows the browser to load these assets more quickly on subsequent visits.
### 6. **Reduce Third-party Scripts**
– Minimize third-party scripts (if any) to reduce the amount of time the page takes to load.
### 7. **Use Server-side Optimization**
– Enable server-side caching and use a performance-optimized hosting environment (e.g., implement server-side caching via plugins or through server technologies like Varnish or Redis).
By focusing on optimizing the image, reducing render-blocking resources, and improving text rendering, you can significantly enhance LCP in your Divi theme's background image and text block section.
### 1. **Reduce or Eliminate Unused CSS**
– **Critical CSS**: Ensure that only the essential CSS for above-the-fold content is loaded first. Tools like **Critical CSS Generator** or plugins (if using WordPress) can help extract and inline critical CSS.
– **Remove unused CSS**: Tools like PurgeCSS can help strip out unused CSS, reducing overall load times.
### 2. **Async or Defer JavaScript**
– Ensure that non-essential JavaScript is loaded asynchronously or deferred. This helps prioritize the loading of content before the JS executes, preventing delays in rendering.
### 3. **Optimize Text Block Rendering**
– **Avoid using heavy fonts**: Make sure the text block isn't being delayed by custom fonts. Reduce font weights or styles if possible.
– **Preconnect or Prefetch for Fonts**: If you're loading fonts from external sources like Google Fonts, use “ to establish early connections to font domains.
### 4. **Lazy-load Below-the-fold Content**
– Ensure that any images or scripts outside the initial viewport are lazy-loaded, so that they don’t compete for resources with above-the-fold content.
### 5. **Use a Content Delivery Network (CDN) for All Resources**
– Ensure your CSS, JS, fonts, and other resources are being served from a CDN for faster global delivery.
### 6. **Server-side Rendering (SSR)**
– If applicable, use server-side rendering to deliver fully rendered HTML to the browser, which can significantly reduce the time to the first contentful paint and LCP.
### 7. **Upgrade Hosting or Use Faster Caching**
– If you're on shared hosting, upgrading to a more performance-optimized hosting environment (such as a managed WordPress hosting solution) could reduce server response times and improve LCP.
By optimizing CSS, deferring JS, and ensuring minimal resource usage for fonts and scripts, you can see further improvements in LCP.
