The web page metrics are used in measuring various attributes of any website effectively. The table given below provides some of the comprehensive web page measures that influence usability. There are various measures or metrics that can be measured in web testing like finding the audience page views, pages per session, devices they are using, types of traffics like direct, indirect, organic, search, and also site content or site speed, etc. 

Measures of Web Metrics:

There are a lot of things that you can measure for growing your website or a business so that there can be more traffic or users available on your website. Some of the best examples that you can measure in your website using the tools available in the market are given below: 

  • Site Traffic: This is the most common metric that every developer or businessman checks for its website growth. It gives us a good indication of your website if it is growing, or declining. It also shows you the various traffic sources like unique visitors or repeats visitors, etc.
  • Bounce Rate: This is also another important metric when monitoring your website for success. The bounce rate tells you the percentage of visitors who leave your website immediately after clicking on it or after arriving. So, thus it means that if the site has less bounce rate then there will be a great growth of the site otherwise the site is not at a good performance.
  • Session Duration: The session duration tells us about how much time a user was active on the website. If your website gets a higher number of clicks, then the session duration will also be higher. As per Google Analytics, if the user is inactive on the website for 30 minutes, it assumes that the session is closed.
  • Site Speed: This metric helps the user to see how much time a page is taking to load. It is calculated as the average page load time.
  • Pageviews: This metric shows which page of your website has more traffic or more views. If you have the idea that which content of your page is most liked by the user, then you can improve or add more content like that so that you can have more traffic.
  • Conversion Rate: This metric is calculated as the number of conversions divided by the total number of visitors. It is a very important topic for those that have a sales website as if they know about the conversion rate of their website, then they can increase their sales profit through this metric. For example, if the site has 100 uniques users and has sales of 25 users, then the conversion rate will be 25/100 = 25%.
  • Devices Sources: This metric shows the type of devices(PC, Mobile, Tablet, etc) a user is opening the website. It can help you in optimizing the website for each device or the operating systems they are using.

Types of Traffic Sources:

We know that website traffic is the most essential metric that every person checks who has a website as it shows how successful the website is. The traffic sources are divided into 4 categories:

  • Organic Traffic: It is a type of traffic that comes from various search engines that a user has searched for. This traffic is the most natural source that a website has earned. It can be increased by applying a technique called Search Engine Optimisation(SEO).
  • Direct traffic: It is a type of traffic in which the user directly comes either by direct the full URL or by searching the website name. This traffic consists of the regular visitors of your site.
  • Social traffic: It is a type of traffic that comes from various traffic sources like Facebook, WhatsApp, Instagram, Twitter, etc.
  • Referral traffic: It is a type of traffic that comes when your website is linked with some other website or comes if the website link is attached to a blog post or any other method as a means of referral.

Now let’s see what are types of metrics used in testing a website. For ease of understanding, the attributes or metrics can be majorly categorized into three categories:

1. Page composition metrics: The composition of a page consists of the arrangement of all visual elements on a webpage like links, words, percentage related to how much size does the page consuming, etc. For measuring the various attributes in a page we test various metrics in the web app page component.

Most of the page composition and page formatting attributes can be easily determined but the difficulty in other one metric i.e overall page quality or assessment metrics needs a separate team or an individual such as a web designer or a web developer. As the web apps differ from each other in various things like the page content, size of the page, the quality of page, reliability, screen, etc. The attributes shown above demonstrate the quantitative web usability metrics that can provide useful insights into distinguishing features of web pages.
