A great tool for gauging demand of a CPA offer is Google Insights (http://www.google.com/insights/search). Google Insights allows you to compare search volume patterns across specific regions, categories, and time frames.




















In the above example, you can see that I have typed in the keyword “ringtones.” Marketing for CPA ringtone offers was huge back in 2003 and 2004 and I made a lot of money promoting ringtone offers. But using a tool like Google Insights, you can clearly see that the search volume for ringtones has dropped considerably.

The search volume was at its peak in 2004 and has dropped to about 40% of its peak volume in 2009.

So although it is still possible to make money with ringtone offers, don’t expect a repeat of the glory days way back in 2004.
