Why should you do this?

1. Allows your site to be accessible to a larger audience (vision impaired, motor skill impaired, cognitive impaired)

2. Search engine friendly pages - clean and simple code enables search engines to spider your pages more quickly and completely.

3. Faster Loading - if your web page contains html errors it will take a longer time for the search engines to spider it, therefore slowing the loading time. If your page doesn’t load in under 10 seconds your visitors may click away to your competitors’ sites.

4. Easier to update and maintain web site - with no mistakes in your html code it is easier and faster to make changes to your web pages.

5. Browser compatibility - validated code ensures your site is compatible with the current browsers and future browsers.
