Why does Page Speed Insights use FCP and DCL and How to Improve It?


Page Speed Insight

There is no doubt that page speed is very important when you have a website. A fast site helps you rank higher in search results, thrives traffic and improves your visitor’s overall experience. Clearly, visitors are not happy when they have to sit around waiting for your site to load. So you know having a fast site is important. But how exactly do you speed it up? Some people are undecided as to just how powerful it is to have a good page loader. If you have slow loading and people have to keep clicking repeatedly on the browser because the images are not loading, or they can’t move from one page to another then you can be sure that the user will not be willing enough to use your page. Ultimately you will end up in losing your customers. Page speed insights help to speed up the website pages not only in the desktop but also mobile devices.

Page speed insights report two metrics:

FCP and DCL

  • First Contentful Paint (FCP): FCP measures the actual time that is taken by a user of the website to see a visual response from the page he is trying to open. It the page loads fast then it will help in keeping the visitor engaged. If not the visitor shall lose interest and shall leave the page. Load time will be very fast i.e. less than 0.4 seconds.
  • DOM Content Loaded (DCL): DCL measures the time when the HTML document has been completely loaded and read. This exactly doesn’t mean that the web page has loaded, it just means that the main HTML of the page has been loaded completely. The page has to then finish loading the images and stylesheets to make the page fully accessible to the user.

Thus FCP and DCL are both important factors for determining that whether the page is Fast, Average or Slow. These two matrices understand the performance of your web page.

  • Fast: The median value of the metric is in the fastest third of all page loads.
  • Slow: The median value of the metric is in the lowest third of all page loads.
  • Average: The median value of the metric is in the middle third of all page loads.

By following the below-mentioned points we can improve the page speed (PSIs:

Clutter Control:

A website is like anything else, it works a lot better when it is organized and not dumped with clutters. So get rid of the spam and old files which are not used anymore. Do this on a regular basis.

Leverage Browser Caching:

It is a process by which certain files of a website are stored in a visitors browser for future use. Loading of the non-cached content slows things down. W3 total cache or WP Rocket are some of the websites for caching.

Minify Resources:

Google doesn’t prefer when the JavaScript or HTML files are too large. They tend to downgrade your site as unnecessary codes affect largely the browser behavior. Thus minifying the resources shall help in improved page speed insights.

Optimize Images:

One should not only compress the images but also specify the dimension. When a visitor visits your site the browser has to determine how exactly to display your content. If you haven’t already specified the size of images the browser has to calculate itself and thus will lead to more time taking.

Prioritize Visible Content:

It is always recommended to show the main content of the site at the top and other related documents later.

Improve Server Response Time:

Poor web hosting, web traffic etc. may be a cause for slow response time. Moreover, many poor plugins can also be a cause of slow response time of the site. Optimal response time recommended by Google is 200ms.

But just make sure that your web page is fast enough to cover new clients for your business rather than parting away with the old ones.
