How to improve website vitals?

 How to improve website vitals?


To improve LCP

Use a content delivery network (CDN)- CDNs cache content in all locations all over the world so that content reaches users more quickly.

Optimise images- Images are often the largest element of a page. Reducing image file size can help speed up image load time.

Implement lazy loading- In lazy-loading, website resources are only loaded when a user needs them.


To improve FID

Reduce the size of JavaScript functions- reduce JavaScript code to improve page responsiveness.

Remove unnecessary third party tools and scripts- loading additional tools on your website can also slow down performance. Reducing the amount of third party tools can improve FID and website speed in general.


To improve CLS

Defining dimensions for images and videos-  All image and video elements on a web page need width and height attributes to avoid unexpected shifts. These width and height properties tell browsers how large an image will be so developers can reserve that space before the image or video loads.


Minimise third party page elements- Third-party elements on a page load from separate locations compared to the rest of the page. Because of this, they may load at a slightly different time, changing the page's layout as they load. Minimising the use of these third-party elements reduces the number of resulting layout shifts. 



All website vitals with its characteristics

Explain all website vitals with its characteristics and its best value.


FCP (First Content Paint)


FCP measures the time a website takes for any part of the page’s content to become visible. This content, whether its text, an image, or any other visual element, acts as a initial signal that the website is actively loading and responding to the user’s request.





LCP (Largest Content Page)


LCP measures the amount of time it takes to load the largest piece of a webpage, which is usually an image or a block of text.  


Google’s guidelines classify a LCP measurement as ‘good’ if it is under 2.5 seconds. Faster is always better.


LCP does not measure how long it takes to load an entire webpage, but it provides a good benchmark to indicate how fast a web page is loading. And typically the biggest element on a webpage is its main content, so the time when it loads is often well-aligned with the time when the user perceives that the page has loaded.





FID (First Input Delay)

It is a measurement of the time between a user’s first attempt to interact with a web page and when it responds. FID quantifies how quickly a person can first click on the screen and make something happen.

According to Google’s guidelines, a ‘good’ FID is 100 ms or less.

Example, Arun searches on google, ‘ how to polish your shoes’ , he clicks on a website photo. FID is the time from when he clicked on right arrow to when the photo starts to load. FID does not measure how long it takes for the requested event to actually occur -how long it takes Arun's browser to finish loading the next photo. It only measures the time between the request and when the request starts to be fulfilled.

Difference between FCP and FID is that FCP focuses on the loading page and what’s displayed while FID focuses on how quickly the page responds to the user’s first interaction.


CLS (Cumulative Layout Shift)

It measures how much a web page ‘jumps around’ when it loads. Specifically it measures the largest ‘burst’ of shifts in the page’s layout.

Google’s guidelines say that a good CLS is 0.1 or less.

A layout shift is when page content moves up and down or in any direction from where it originally appeared. In context of metric, a burst is a group of layout shifts that all happen with a second of each other. A Burst can be upto 5 sec long and contain any number of layout shifts.

Example- when a web page opens and is loading, you see a image, then the image suddenly moves further down the page and you end up clicking on the text that loads above the image. So, CLS should be low to have good user experience.



TTFB (Time To First Byte)

It measures the time when a user’s browser makes a request and the browser receives the first byte of data from the server.

Most websites should strive to have a TTFB of 0.8 sec or less. A faster TTFB means a better user experience because it directly impacts how quickly a page can begin loading.

Difference between TTFB and FCB is TTFB is about the server's response time and it measures the time a website takes to load only one byte of data while FCB measures the time it takes for a user to see first content on page and its data can be any bytes or kbs etc. In short, we can say, FCB includes TTFB.





How Website Vitals impact Website Performance?

How Website Vitals impact Website Performance?


CWV (Core Web Vitals) significantly impact website performance by improving user experience and SEO rankings. Good CWV scores translate to faster loading times, improved interactivity, and a more stable visual layout, ultimately leading to higher user satisfaction and engagement. These improvements also positively affect factors like bounce rate, time on site, and conversion rates.


Google uses CWV as ranking factor, meaning websites with good scores are more likely to rank higher in search results. This is because Google prioritises providing users with the best possible search experience and websites with good CWV contributes to that.

CWV like LCP, FID and CLS directly measures user experience. Faster loading times (LCP), responsive interactions (FID) and stable visual layouts (CLS) all contribute to a smoother and more enjoyable browser experience.

If users are dissatisfied with a slow, unresponsive, or unstable website, they're more likely to leave quickly (bounce). Good Core Web Vitals scores help reduce bounce rates by providing a smoother and more satisfying user experience. 


Website Vitals

 What do you mean by Website Vitals?


Web Vitals are a set of metrics introduced by Google to measure and improve the user performance on websites. These metrics focus on key aspects of page performance including loading speed, interactivity and visual stability.

Core Web Vitals are particularly important for positive user experience and are used by Google in its ranking algorithms.

Tools for measuring and improving web vitals include Google PageSpeed Insights, GT Metrix, Chrome DevTools etc.

Difference between Website and Landing Page

 Difference between Website and Landing Page


Website

  • It contains multiple web pages.
  • The content is mostly informational
  • Distractions are there- hence can dilute the focus of visitor.

Landing Page

  • It is a standalone web page.
  • It is mostly transactional, focuses around Call To Action. Designed to a specific Marketing goal.
  • No distractions. Can be used to grow your email list, sale of product and service, event sign up page etc.
  • Single goal, big clear CTA, social proof, chatbot.


Landing Page

 What do you mean by Landing Page?


A landing page is any web page that a customer can land on, but in marketing, it is a standalone page, distinct from your homepage or any other page that serves a single and focused purpose. It’s where visitors land after clicking on a link in an email, a paid social ad or a paid search ad.

Unlike web pages, which typically have many goals and encourage exploration, landing page are designed with a single focus or goal known as CTA (Call to Action).

It’s this focus that makes landing pages the best option for increasing the conversion rates of your marketing campaigns and lowering your cost of acquiring a lead or sale.
