On 2005-Dec-05, I received the first check from Yahoo! publisher network (YPN) and may be I started using it a month before that. Even though I could not find any info on when I joined the YPN, may be good idea if they could display in the YPN profile whats the age of the account…I am still successfully running the YPN on all my blog sites (currently this is the only active blog, rest of them are all history).
Before switching to YPN, I used to have Google adwords; and once I made a switch, I never had a chance to look back…and never had any problems with YPN…interestingly I found YPN was displaying the content related ads much better than adwords by picking the tags from the blog entry…where as adwords most of the time used to display random ads which are not even related in any form.
I am waiting eagerly for the YPN international version since the current version of YPN doesn’t serve non-US folks like me :(.
