User Interface (UI)

The percentage of users on your website that leave the site without taking a single action. While no website has a 0% bounce rate, a high bounce can indicate that your site - or a particular page on a site - is not delivering the information that the user expected to see when they visited it.

Agile Development - sometimes simply called Agile - is a project management style that emphasizes quick, iterative changes to a project to maintain flexibility in the project’s parameters and deliverables.

This is often juxtaposed with Waterfall Development, wherein an entire project is completed in stages before any launch happens. Testing and iterating in Agile often happens during development, with the initial launch happening much earlier in the process to get quicker feedback.

Hick’s Law is a psychological principle that, in a marketing and web design context, relates to the number of options presented to a user. The more options a user is given, the longer it will take them to make a decision. Therefore, best practices in web design, for instance, include minimizing clutter and non-essential options from major pages, in order to focus user attention on those items you consider most important.
