Since I made the switch 6 months ago to a tableless design on my main site, I've noticed some interesting things:
* My search engine rankings have dramatically improved
* My bandwidth usage has dropped about 50-75%
* I can now make changes to the look and feel of my site easily by just changing the one file, the stylesheet.
Let's look at why my search engine rankings improved. Now that I have less un-indexable code on my pages, the search engines can now spider my site quicker. Less code, more content, therefore a better ranking. Makes sense, doesn't it?
Bandwidth costs money, and unless you have a really good hosting plan with lots of bandwidth, then your larger files will take up more room on your server, and take a lot longer to load. Tableless designs use up considerably less bandwidth and are more accessible.
Every once in a while I may want to alter the look of my site. I like to change font colors, link colors, menu items, etc…Before I started using tableless designs, these changes took me hours to do. Now I just open up my stylesheet, make the changes I want, and in a few minutes I have my site updated with the new look and feel. It's so easy!
