Web Usability

Just like web accessibility, web usability should definitely be a topic that a website developer should pay attention to. Some of the things that to keep in mind for usability are listed below:
1- Efficiency: The structure of the site should be efficient...
2-Task Flow: the flow is important as a usable site has a page flow that must match with the workflow.
3-Replication: It's ok to use templates!
4-Testing for usability: Testing early is very important within the design stage. A designer should not wait till the end to do this. HTML, Javascript should be tested for compatibility.
5-Motivation: The design for the website should meet the specific needs of the user. The design should motivate different types of users to specific parts of the site.
6-Track the traffic: Keep track of which page gets hit the most. Which page do people spend less time and click right onto the next page immediately? The site can be adjusted accordingly.
