Your webpage may have an enormous network payload error. The data sent through a network is its payload. A web page’s payload is the collection of files sent to a user. The larger the files are, the bigger the network payload. This could lead to a slower page. Learn more about avoids enormous network payloads.
When you’re evaluating a website’s page speed performance, one of the first things a performance audit tool may look at is the number of HTTP requests made and the size of each request to calculate the total network payload. If your page has many HTTP requests, it'll typically take longer to load. Learn more about the keep request counts and file sizes small error.
One of the main contributing factors to page speed is how long your page takes to load. Time to interactive is the number of seconds it takes for content on your webpage to become functional for the user to interactive with it. It's important because each user may experience different time to interactive depending on internet speeds. How do you make your time to interactive fast?
If you want to improve your website's performance, look no further than optimizing your server static assets with an efficient cache policy. Caching helps your website load faster for visitors if the user visits your webpage again before the cached page expires. The cache files are static assets like JS, CSS, and image files. They are stored in your server until called by the visitor. How do you implement HTTP caching to speed up your site on repeat visits?
One of the contributing factors to your website's speed is the number of redirects that occur before your page is displyed. With all else equal, the more redirects that your page has, the longer your page will take to load. This is because as the redirects occur, nothing is being shown to the end-user. How do you minimize the number of redirects from one URL to another?
Images that aren't optimized for your webpage could be slowing down your site. And sometimes, we may not even know that it's happening. If you're displaying images at a low resolution, say 300px x 250px, you'll want to make sure the image's file is the same pixel dimensions. If your image is a larger pixel dimension, your browser will still have to download the full image resolution to display it at a lower resolution. Using an image with a higher pixel resolution doesn't add a crisper picture if the image isn't being displayed at that resolution. How do you fix the properly size images error?
The less unnecessary JavaScript that your page has, the faster your page will load (all else being equal).

The less unnecessary CSS that your page has, the faster your page will load (all else being equal). If you can identify areas where you CSS can be minified (or minimized) without changing your page's experience, then you've found an opportunity to make your page faster. How do you minify CSS?
