Site Speed
Core Web Vitals are a set of three specific page experience metrics that Google considers to be very important:

LCP (Largest Contentful Paint) - is the time it takes to render the largest image or text element visible in the viewport, relative to when the page first starts loading.
FID (First Input Delay) - The time it takes for a user to interact with a page for the first time (including clicking a link, clicking a button, or using a custom JavaScript-driven control) until the browser actually gives the result of the operation.
CLS (Cumulative Layout Shift) - Images or text appear to be shifted in position due to lazy loading
Google's system evaluates a web page's status indicators based on the following ranges, and these indicators can be viewed through the Google Search Console backend:

good Needs improvement Poor
LCP <=2.5 seconds <=4 seconds >4 seconds
FID <=100 ms <=300 ms >300 ms
CLS <=0.1 <=0.25 >0.25
Core web page indicators became one of the ranking factors, and these indicators are actually related to page load time and used as reference indicators. Slow page time will also hurt your ranking because it will give users a poor experience, which is a big problem in the eyes of Google.

According to Google , page speed determines the ranking of search engine results, whether on a computer or mobile device. If the loading time of a mobile page exceeds 3 seconds, more than half of users will choose to abandon the website. For a website, those few seconds determine the key to user stay, and missing them is equivalent to missing a huge opportunity.

Not only that, your website loading speed (or slowness) will also affect your organic search ranking and cost per click. So if your website loads slowly, your customers are likely to be lost to your competitors!

How to increase website speed?

Website speed is generally determined by two aspects: the quality of the website server space and the website itself. There are many web hosts on the market that are optimized for speed, especially for WordPress websites. Choose a good hosting provider to provide basic guarantees for website speed to meet the performance of your visitors and Google search engines.

As for websites, common methods include reducing the loading amount as much as possible, compressing the size of multimedia files before uploading, avoiding the use of too many external programs, optimizing CSS and Javascript, and enabling cache plug-in functions.
