You would not believe how many blogs out there have bad coding.
There are thousands of them.
Its a shame!
Good coding, one that is up to W3C standards, is one of the most basic keys to google adsense revenue. It is what allows our pages to get indexed properly and more importantly helps us rank for long tail keywords.
Ah, yes, the long tail keyword. Gotta love it. You will find the longtails, collectively,will produce more adsense income than the actual keyword you are going for. And many times the searchers putting in a longtail phrase are most targeted traffic than people putting in the general phrase that have the most volume. I found that out today when one of my sites about household appliances made me $4.00 and all three clicks were extreme long tail versions of the main keyword I was going for. Go figure!
Now if you use Blogger, Blog, Blogetery, or Tumblr (some of the top free blog hosting services) you will not have to worry about coding. Mostly everything is done for you. But, if you are using WordPress, and many of us including myself are, then you need to go in and change the coding if it has any symbols, numbers, or signs in it.

That is the default coding structure of all new WordPress installations. Why? I have no idea. Many its a conspiracy to keep more people working for “the man.” I do know however this has to be changed for optimal results.

I will admit that I myself went overboard on the URL permalink structure because http://googleadsenserenveue.org/adsenserevenue/good-coding-great-adsense-revenue is too much and probably hurts me a little.
Wait!
Before you go and do what I just said you need to do something first. You need to download Deans Permalinks Migration. If you do not then you will manually have to do a bunch of 301 redirects. Google has already indexed your pages. If they see another URL with the exact same content (search engine does not know it is really the same page) they will ding you for duplicate content. This is a serious penalty and can push you back in the rankings four to eight pages.
