What is a Large Website?

A website with a significant amount of content, features, and functionality – Large Website.

Categorizing a website as small or large can be subjective in the context of website design. Some people have the intention that a website with 100 pages is large, others may consider a website with over 1,000 pages as large.

Generally, large websites are commonly associated with and used by governments, universities, and enterprises. Such websites can have several hundred to a few thousand pages, and some can even have up to a million pages.

Why is Performance Important for a Website And on What Factors Are They Measured?

Web performance is crucial for a website because it directly impacts the user’s experience. Slow-loading pages, unresponsive interfaces, and sluggish browsing can lead to a frustrating experience for users, resulting in them abandoning the website and possibly turning to a competitor. This can harm a business’s revenue and reputation. Additionally, website performance affects search engine rankings and can lead to decreased visibility and traffic if a website needs to be optimized for speed and responsiveness. In today’s fast-paced world, users expect websites to load quickly and provide a seamless browsing experience, and businesses that prioritize web performance can gain a competitive advantage by meeting those expectations.

It is the same for large websites. Performance plays a major role even if you run a website with over 1000 pages. 

The Key Performance Indicators

Identifying performance objectives is essential and can be achieved by establishing key performance indicators (KPIs) aligned with business objectives. To measure the influence of user experience and performance on the overall revenue of the business KPIs play a significant role. The following are some KPIs to consider,

Conversion Rate – Calculates the percent of your traffic that takes an intended action. Actions such as completing a purchase or signing up for a newsletter. When a business site is slow, it can prevent users from completing their intended tasks, leading to low conversion rates.

Time on Site -The average time that your users in aggregate spend on your site. When a site performs slowly, users are more likely to abandon the site prematurely, leading to low time on site metrics.

Net Promoter Score – The net promoter score (NPS) is a metric for assessing customer loyalty to a company’s brand, product, or service. Poor user performance experiences can lead to poor brand reputation.

How to Improve User Experience for Large Websites?

Improving user experience for large websites is quite challenging, but it can be achieved by implementing a few practices.

Simple Navigation

Large websites should have clear and intuitive navigation which would help users find what they need quickly. Use categories and subcategories to organize content, and make sure that the navigation menu is easy to find and use.

Improve Site Speed

A slow website can frustrate users and lead to a poor user experience. Optimize images, minify code, and use caching to improve site speed.

Use Responsive Design

Make sure that your website is optimized for all devices. The devices would include desktops, laptops, tablets, and smartphones. This will help users access your site no matter where they are and what device they are using.

Implement Search Functionality

A search bar on your website can help users quickly find what they are looking for, especially if the site has a lot of content.

Provide High-Quality Content

Large websites should provide valuable and informative content that is easy to read and understand. Break up long blocks of text with headings, bullet points, and images to make it easier to scan and digest.

Use Calls-to-Action

Use clear and prominent calls to action to guide users to take specific actions, such as signing up for a newsletter, filling out a form, or making a purchase.

Test User Experience

Use user testing and feedback to identify areas of the website that need improvement. Make adjustments based on user feedback to improve the overall user experience.

What are Core Web Vitals – How Can They Help in the Performance of Large Websites?

Core Web Vitals – essential for all web experiences. Core Web Vitals is a set of metrics that can measure important aspects of user experience, including loading speed, interactivity, and visual stability. 

The metrics include Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). 

Page Speed Insights User Experience Guide - A part of Large WordPress website development guide

By measuring and improving Core Web Vitals, large websites can provide a better user experience and improve their search engine rankings. Users are more likely to stay on a website that loads quickly, easy to navigate, and provides a good user experience. Additionally, search engines like Google now use Core Web Vitals as a ranking factor, which means that websites with better Core Web Vitals are more likely to appear higher in search results.

LCP (Largest Contentful Paint)

LCP measures the time it takes for the largest content element on a webpage to load and become visible to the user. This content element could be an image, video, or block-level element such as a heading or paragraph.

Google recommends that LCP should occur within the first 2.5 seconds of the page starting to load. If it takes longer than this, it may negatively impact user experience, which in turn could affect search engine rankings.

FDI (First Input Delay)

Here, the question is can the user interact with your website? Well, exactly that is what is measured by the FDI.

FDI measures the time between a user’s first interaction with a website, such as clicking on a link or button, and the website’s response to that action. It measures the website’s interactivity and responsiveness to user input. A long FDI can indicate that the website is slow to respond to user actions, leading to a frustrating user experience.

To achieve a good user experience, the FDI score should be less than or equal to 100 milliseconds according to Google’s guidelines for Core Web Vitals. If the FDI score is higher than this threshold, it may indicate that the website is slow to respond to user input, which can negatively impact the user experience.

To improve FDI, you can optimize code and reduce the size of JavaScript files, defer the loading of non-essential scripts, and use a content delivery network (CDN) to deliver content more quickly. Additionally, reducing server response time and using browser caching can help improve FDI by reducing the time it takes for the website to respond to user input.

CLS (Cumulative Layout Shift)

CLS calculates the number of unexpected layout shifts that occur during the loading process. Unexpected layout shifts can be frustrating for users as they cause content to move around on the page, resulting in a poor user experience.

Google has set a target score of less than 0.1 for CLS to ensure that web pages have a good user experience. To improve CLS, you can ensure that images and videos have dimensions specified in HTML, reserve space for ads and embedded content, and use appropriate CSS and JavaScript to control the layout of the page.

Hence, Core Web Vitals helps in improving the performance of large websites, leading to better user experience, higher search engine rankings, and ultimately, more traffic and conversions for your extensive website.

Tips to Improve Your Individual Core Web Vitals Score


  • Optimize images and videos: Large images and videos can impact LCP, so compress them and reduce their size to improve loading times
  • Minify CSS and JavaScript: Minimizing CSS and JavaScript files can reduce their file size, which can improve loading times and boost LCP
  • Use a Content Delivery Network: A CDN can help reduce server response time and improve LCP by caching content
  • Use lazy loading technique: Lazy loading is a technique that defers the loading of non-critical resources like images and videos until they are needed. This can help improve LCP by allowing the largest content element to load first
  • Optimize web fonts: Web fonts can also impact LCP, so it’s important to optimize them by reducing the number of font weights and styles used on a web page
  • Reduce server response time: To reduce server response time, you can use a faster web hosting provider, optimize your website’s code, and use caching


  • Minimize Third-Party Scripts: Third-party scripts can cause delays in page responsiveness, so it’s essential to keep them to a minimum. Only use necessary scripts and avoid using them on critical rendering paths
  • Optimize JavaScript: JavaScript can significantly impact FID, so it’s essential to optimize it for faster execution. Minify and compress your JavaScript code, remove unused code, and use asynchronous loading where possible
  • Use a browser cache: By implementing this approach, your page’s content can be loaded more quickly, allowing your users’ browsers to complete JavaScript loading tasks at an even faster pace


  • Set Dimensions for Media: Ensure that images, videos, and other media on your website have explicit dimensions set in HTML. This helps the browser reserve space for the media before it loads, preventing layout shifts
  • Avoid Dynamically Injected Content: Content that is added dynamically to the page after it has loaded can cause layout shifts. Avoid this by specifying the space that the content will take up in advance, or by loading it asynchronously
  • Reserve Space for Ads: If your website has ads or other embedded content, reserve space for them on the page in advance. This can prevent layout shifts when the content load
