Website Hierarchy
• 1st Level Pages – One click away
 More Internal links

• 2nd Level Pages – Two click away
 Less Internal links

• 3rd Level Pages – Three click away
 Very less Internal links


Broken Links Two reasons for broken links 1. File name wrong spelling 2. Target URL expired Use Xenu tool to find this!


Programming Guidelines

• I Frame Tag
 The <iframe> tag defines an inline frame that contains another document.

• Java Script files
 Call external JS files if needed. This will help to reduce the file size.


Google Analytics
• Mozilla Google analytics plugin
 Install this plugin in your machine. This will highlight a colored symbol in task bar of the browser if a page contains analytics code.  Be sure to check GA tracking code before delivering the project.
