Heres a quick method Ive used with one of my websites to get 20,000 hits in a month from Yahoo Answers. KEEP IN MIND I was totally slacking on this method so you can actually get a lot more hits than that.
1) Sign up for a Yahoo email account (Hopefully you already have one thats aged)
2) Find your way to Yahoo Answers: Yahoo! Answers - Home
3) Search up questions using one of your keywords
4) Answer questions honestly and leave your link in the source section
5) Follow steps 3 & 4 as many times Yahoo allows you (Between 20-40 times) a day for ATLEAST 3 days a week
*IMPORTANT* DONT TRY AND SPAM BECAUSE YOU WILL BE BANNED! ANSWER QUESTIONS THOROUGHLY NO HALF ASSING!
