i'm collecting a list of the most ingenious sites that are fueled entirely by search. my personal favorites are http://www.retailmenot.com and http://www.whocallsme.com . retailmenot definitely makes more money but whocallsme is hilarious and very useful.
Yahoo Answers?<p>Surely nobody actually goes there intentionally, creating a website dedicated to giving the incorrect answer (but with an awesome page rank and truly unique rants) to your every Google Search, and twice-weekly providing the Fail Blog with material.
To be honest it's not advisable to rely only on search traffic. I say that as a SEO. Returning visitors and often even type in or direct visitors are much better.<p>Many spammy sites rely solely on Google/search traffic.<p><a href="http://hubpages.com/" rel="nofollow">http://hubpages.com/</a> for instance.
