Core Web Vitals – Importance

The user experience metrics of LCP, TBT, and CLS are mainly dependent on the theme layout, design, theme configuration, JS elements, render-blocking resources, largest block size above the fold, and many others.

In this case study, we will see how core web vitals on DreamPress plan score with GeneratePress theme. 

Test Scenario with DreamPress Plan

We have already done a case study of the effect of the DreamPress plan on TTFB (time to the first byte) times. The same website consisting of many active plugins, themes, and other resources are used. The web page is also the same.

Core Web Vitals and DreamPress – Using WebPageTest

The following are the results for LCP, TBT, and CLS.

As we can see above, LCP and CLS were in green limits. It indicates that the DreamPress user experience is good enough, and the layout, theme configuration is also good.

When there are no large paint objects, LCP would be good. On the same side, if there are not too many movable elements, CLS is green.

But due to too many AdSense ads above the fold, the TBT value was in red.

We can also use WP Rocket to defer JS code and load lately. It may improve the total web vitals.

DreamPress and Core Web Vitals – Using GTMetrix Test

The core web vitals results are as below.

As we can see above, LCP and TBT are in red. The total page size is around 2.72MB. Video and JS constitute about 2.0MB. The number of page requests is 367. Others, JS, Img, were the leading causes for this many requests.


Though the host does not play many roles in user experience, we can see that the main web vitals are all good with DreamPress and GeneratePress configuration. For TBT, we either need to optimize the existing website code or remove the ad JS elements. – WebPageTest

As this site also loads video ads, the loading is a never-ending one. It is one of the primary causes of high loading time. Also, the Adsense Ads and video ads contribute to the high LCP and TBT. Since the height element is restricted in the Ad Inserter Pro plugin, CLS is low – GTMetrix Test.
