Every product or service has its certain level of usability which depends on a number of factors. If we speak of a website, it can be evaluated under the same criteria as a product designed for people, which means we can evaluate its effectiveness in relation to users’ roles, external conditions and tasks that users need to perform.
After we collect all data we can compare it against the standards of comparison. The aim of this testing is to understand what a product lacks compared to your competitors and what should be improved.
In this post we will speak on three main methods helpful for evaluating the usability of your website or app. We will also share the plugins that will help you improve your usability, understand the behavior of your users and get the results in the shortest possible time very easily.
The Essence of Usability
The usability can be defined as a mix of effectiveness, level of quality and user satisfaction. In other words, the usability is about completing the tasks and understanding how satisfied a user is when trying to complete these tasks.
A usable website or application allows users to get their tasks done in the shortest possible time without any delays and without any errors. As a result, a user is satisfied with a product (an app or a website) and they are ready to use this application or visit this website again in the closest future.
So we will speak of three methods of evaluating usability to analyze the effectiveness, the level of quality and user satisfaction – all in a context of use.
1. Identify the Effectiveness
When evaluating the effectiveness of your website or app, it’s important to consider the completion rate which refers to the amount of users that reached their goals successfully. No test moderators should assist with the test. Before you test your website or app, define an amount of scenarios to test. If your completion rate is above 78% – it is the acceptable percentage of effectiveness.
2. Estimate the Level of Quality
The level of quality (the efficiency) refers to the average time required for a user to complete a certain task. You can also consider the time taken on the first attempt, time that a regular user requires to do a task compared to an expert, time for correcting errors, and more metrics. Based on industry standards of comparison the average amount of errors per task should be no more than 0.7.
3. Evaluate User Satisfaction
User satisfaction is measured with the help of SUS (System Usability Scale) which has become the industry standard and consists of 10 item questionnaire with five response options for respondents. These questions allow to evaluate the users overall impression about the product they have tested.
After you get the results you can compare them with industry benchmarks and then make a conclusion on what you’ll have to change and improve to make users satisfied.
Here are some useful solutions that will help you both test your website usability and increase the amount of satisfied users in the simplest possible way:
Split Test URL Rotator Plugin for WordPress
A great plugin to improve your usability, increase sign-ups amount, and get a better conversion. The plugin allows to make A/B testing with a lot of landing or offer pages. It helps to setup an unlimited number of split tests to compare any number of URLs, and more. The plugin tracks how many times every page was shown; and you can setup every page to be displayed during a certain amount of time. You can also setup an unlimited number of URLs for the split tester to rotate through.
Hotjar Tracking All-in-One Analytics & Feedback
This is a new and easy way to truly understand your website visitors and your application users. Heatmaps and Feedback Polls understand the needs of users, Recordings identify usability issues, Conversion Funnels look for the biggest opportunities for improvement and testing, Form Analysis improve online form completion rates, Surveys collect deeper insights from your customers as soon as they convert, and Recruit User Testers recruit your users for one-on-one testing and interviews.
EmailChecker – Ultimate Email Hygiene!
This is an ultimate solution in usability and improving user experience. As a huge percentage of users mistype their email addresses during signing up, joining mailing lists, or while creating accounts, this plugin can decrease the number of signup errors and bounce emails by 50%! It can be used for batch processing to perform in depth list hygiene.
The mentioned above measures are almost always appropriate but if you want to make more testing and evaluation make sure that any metrics you choose are relevant and worth your time as well as meet your goals.
