General Usability Analysis

General analysis Structural analysis GUI analysis
TU Dublin title tag reads 'Home' and landing page reads 'our future is full of infinite possibilities'. YouTube only has its name as the home tag and landing page is a call to action to listen to music, even though it's a video website.

Udemy has "Learn anything on your schedule" and landing states "Learn on your schedule. Study any topic, anytime. Explore thousands of courses starting at €14.99 each". Udemy's purpose is clear, TU Dublin and YouTube are not.

Language used for both TU Dublin and Youtube assumes you are familiar with their site. Udemy's landing page text is understandable and clear. Using Google PageSpeed Insights response time for TU Dublin which scored 58 on mobile. Udemy scored 56 and Youtube is 47 on mobile. All are not adequate response times. Both YouTube and Udemy provide concise information. TU Dublin is scattered throughout its navigation.
TU Dublin navigation does not link to all important features as there are two many. Its main features are broken up into student users and staff users.

Youtube navigation is clearly pointing user to trending feature Udemy points users to categories of course or how they can teach their own.

All have elements of unnecessary scrolling but this was not significant. Control forms are in correct place on all websites either to allow the user to quickly search or funnel them into important features.
