What is markup and how does markup impact my web site?
Markup is a type of computer language that is used to indicate the structure of a document. i.e. how the information within that document relates to itself and other information.
Markup, specifically HTML, is the core of any web page on any web site. The markup of the web page tells the web browser what pieces of the content mean and how to display them to your site visitors.
Proper markup will help search engines index your web site correctly, which will help internet users to find your web site or your business. Correct markup will also help web browsers to load and display your web site more quickly. In addition, proper markup will help disabled users to access your web site and get your information so they can be your customers as well!
