Largest Contentful Paint (LCP)

Largest Contentful Paint (LCP) is a Core Web Vitals metric that measures the loading performance when a webpage is displayed on the user’s screen.

LCP should be less than 2.5 seconds of page loading for better rankings.

First Input Delay (FID)

FID measures the time when a browser responds to the user’s interaction for the first time on your webpage.

After tapping on a button or after clicking on a link what time it takes to respond is called FID.

First Input Delay Example

If your page’s elements are light enough, then it responds within reasonable limits.

FID should be less than 100ms for better rankings.

Note: FID is also hampered by users low-end device or slow CPU.

CLS is a core web vital metrics depends on visual stability. It’s a common thing for a user to face the distraction of visuals shifting that experienced bad UX. So, you need to ensure the stability as it will be a ranking factor in upcoming days.

Overall Page Experience You need to know:

Google now wants to focus on the overall page experience to provide the best results for the user.

So, how should you consider:

  • Page loading speed is a major factor(LCP, FID, CLS).
  • Lightweight theme and plugins.
  • Detailed Valuable content.
  • compressed Images and other elements.
  • Elements dimensions. (make sure to define the width and height of your visual elements).
  • Visual stability.
  • Readable fonts.
  • A perfect distance maintains in elements(ex. buttons) especially for mobile users for preventing them from accidentally pressing other buttons instead of which they want to tap on.

Google also updated its popular developer tools such as Lighthouse and PageSpeed Insights to surface Core Web Vitals information and recommendation.

What are the 3 things you need

As I’ve mentioned earlier in the overall page experience section, all things you need to improve for better rankings.

But initially what 3 things you need to consider, are:

  • Fastest Web Hosting
    • You can go WP Engine Web Host, Site Ground, Bluehost, A2 Hosting, Hostgator and more and more………
  • A lightweight and mobile responsive theme with content focused
    • Fortunately, now maximum themes are mobile responsive and lightweight. Check if your theme has these things or not.
  • Compressed Media
    • Make sure your images or media should not exceed 100kb each. As low its size as better. You see, niksguide’s images have an avg. of 25kb size.


In the next year, 2021 Google will apply core web vitals for rankings. Google may not consider your site’s AMP version in upcoming days. So, if your site has problems yet, make sure to improve your website for preventing your rank drop.

Share it to inform others before their ranking drops. Comment here if anything you want to know.

Thank you for being here.

Regards Niks.
