Google, one of the famous search engines, has officially added Core Web Vitals to its search algorithm. It is a set metric that measures a site’s ability to provide a pleasant user experience. Google Core Web Vitals was added to its ranking signals in July 2021. Here are ways to improve core web vitals.
- Optimize JavaScript Code
The most common reason for significant delays when opening a website is heavy JavaScript. This happens because the browser blocks the webpage’s main thread from processing JavaScript downloads, analyses, compiles and initiates.
A technique that speeds up execution is code-splitting. Code-splitting is a technique that allows web developers to break down large JavaScript bundles into smaller, conditionally loaded pieces. After code-splitting is complete, you can defer and async any JavaScript that is not critical, such as scripts from other parties.
If possible, you should use prototype inheritance over functional inheritance. This is the most efficient method because it only creates one copy of a property or method. Functional inheritance, however, does not have this advantage because it creates duplicate properties. If your objects are very large, this can be a problem. You can pass them to constructor functions as arguments. All instances will use the same object resource. Remember to use prototype inheritance if possible.
Make sure to avoid unnecessary watchers. While this is a good way to make your app responsive, it can be slow, especially if your users have to scroll. In such a case, it’s better to use requestAnimationFrame. JavaScript will run at the start of the frame and not over a long time. Event handlers should complete tasks in a matter of seconds to be considered efficient.
- Optimize Images and Videos
Optimizing image and video elements is essential as optimizing them will make pages lighter. This will improve the loading speed, LCP score, user experience, and search engine rankings. Typically, companies look for quality graphic outsourcing services to help them achieve their marketing goals.
For landscape photos, always save graphics in jpg and png formats. Developers may also use modern designs such as JPEG 2000 or JPEG XR.
Web owners may also add height and width attributes to image and video elements. They can also reserve the space using CSS aspect ratio boxes to prevent unplanned layout changes. Web owners can use these methods to ensure that the browser provides the right amount of space in the document for the image while it loads. Firms can invest in a graphic design outsourcing website to save time and effort while focusing on more essential things.
- Google Analytics
Another helpful tool to help with Core Web Vitals is Google Analytics. This tool collects anonymous data from Chrome users and classifies the overall performance of your website. If at least 75 percent of your page views meet the Good threshold of Core Web Vitals, Google gives your website or page a good score. It doesn’t affect the performance of other pages on your site. You may be surprised by the results! So, take your time and improve Core Web Vitals today!
