I came across this article http://www.freealerts.org/adsense-expensive-keyword/dumbest_adsense_mistake.php
Which talks about the highest pay outs for adsense. Here is the top phrase “selling structured settlements” – pays out $64.81 per click. The problem is the click rate is low.
The best keywords are ones that pay well and get high click through’s. For example: “insurance” pays over $17 per click. The average clicks per day is 49,893.5, according to this article. Might be a good way to make some cash.?Ǭ† The problem there is flooding the engines will crappy content to make that money. Google had created a huge money hungry monster. That monster is killing search engine results.
