In 2018, the average time to fully load a mobile page was 15 seconds. Photo Retouching This is significantly longer than Google's recommended page load time of 3 seconds. So, of course, reducing total load times is a top priority for interacting with users as quickly as possible. However, page speed isn't just about total page load times. It is also a user experience in 3 seconds (or 15 seconds). It's important to consider how efficiently your page is being rendered . This is achieved by optimizing important rendering paths and reaching the first paint as soon as possible. Basically, it reduces the amount of time users spend looking at a blank white screen and displaying visual content as quickly as Photo Retouching possible (see 0.0 below).
Optimized page rendering Examples of optimized and non-optimized renderings from Google There is an entire process outlined in Google's developer guide documentation Photo Retouching (Thanks, Ilya Grigorik) for how to do this, but with a particular focus on one big hitter: reducing rendering block resources. advertisement Continue reading below What are the important rendering paths? An important rendering path is a series of steps that a browser takes to render a page by converting HTML, CSS, and JavaScript into the actual pixels on the screen. Basically, the browser needs to request, receive, and parse all HTML and CSS files (and some additional work) before it can start rendering the visual content. The user will see a blank white page until the browser completes Photo Retouching these steps.
Steps to render the page How can I optimize it? To improve the critical rendering path, you need to identify and analyze the critical resources (the resources that block the first rendering of the page) and look for opportunities such as: advertisement Continue reading below Reduce the number of important resources by deferring rendering block resources . Shorten the critical path Photo Retouching by prioritizing non -scrolling content and downloading all important assets as soon as possible . Reduce the number of critical bytes by reducing the file size of the remaining critical resources . This article focuses on Step 1 – Deferring Render Blocking Resources (that is, rearranging elements to make them more efficient and making the experience feel faster without removing content).
