Their are many simple factors that can improve your Adsense earnings, but the easiest one is, not to concentrate on making money from your website or blog, but to build up a constant stream of new and returning traffic first. We all know that our websites or blogs are useless without traffic, and so is Adsense, but without first building up a fan base that will return over and over, not forgeting new traffic that will give you a big boost to your earnings, all your hard work will be worth nothing.
I also recieved an e mail from Web Pro World, one of the most popular forums for professional site builders, basically they are saying that Google dosent look at Keywords in the URl's anymore.
That was a big query of mine a few months back, should i be buying URL's based upon my Websites and Blogs.......seem's i dont need to anymore.
