Someone just saved me a lot of time…
A while back, a “big league” adsense earner gave me some heads up about using properly formatted code on my pages, so that the SE spiders would handle it better and rank the pages better. His arguments on the whole made sense, and I certainly couldn’t argue with his income levels. But I just never took the time to really figure out all the areas of proficiency I needed to have when it came to coding my templates properly. HTML and CSS can be such a pain in the rear!
