Though a simple trick, to ensure that your content is more distributed in mant pages over your blog. People hate long pages. They would rather have many brief pages than one longgggg page with all the content. Dont have all you blog having like seven posts. Edit this default setting in blogger.com and set it to one or two posts. Note, this is only applicable to those of you who have a blogger acount. but I just thought might be essential for some other webmasters to note this too. Like in blogger.com, let your posts be each in its own page. I've implemted the trick in this Poetry blog. This Ensures that your content is distibuted and so is your adsense!! I figure, the more the pages, the more the content(Put Quality Stuff), then the more the Earnings in a way. Login to your Blogger account and try this trick.
This does not apply to people who use blogspot mainly to provide link juice to their real sites. Links in the main page give more juice.
