The author's thesis was quite intuitively illustrated by the Google AdSense "Heat Map", which depicted a schematic of your typical web page, with a header, navigation bars down both sides, a footer, and some blocks where the content lay.
Heeding the advice of the Heatmap by placing one's Ad Units in the "Hot Spots" on one's old pages quite commonly doubled one's monthly revenue.
However the last time I went to look for it at Google's AdSense support site I could not find it. I don't know whether they moved it or took it down.
For your own purposes, try placing important links at different places on your pages, leave them there for a week - as the traffic to most sites tends to be cyclical with a one-week period - then analyze your web server logs so as to determine how many internal referrals to other pages on your own site resulted from each link.
I analyze my own logs with Analog (http://analog.cx/) which is powerful and configurable but has a steep learning curve. If you don't have the headspace to Read The Fine Manual, there are many fine competitors readily available.
Each subsequent week, move each of those experimental links to a distinctly different place on your pages.
Upon finding the most-effective placement for each link, put all the links in their best places, then try altering their presentation: text color, typeface size and style, backround color and the like.
Once you've found the best combination of everything, you will be in a good position to earn some coin via PPC ads.
I myself for three solid years earned $3,500.00 per month on the average, $5,000.00 for two different months, with just two Ad Units on just one single quite lengthy, well-researched piece on copyright law:
