Can a new site ever make it big these days?
Hi, I have just started a new site, MarketGround.com.
I have designed it to be a Free Online Classifieds Forum.
My question is, do I stand any chances to ever make it big, and become popular? If yes, what search engine marketing strategies would you recommend?
Thanks a lot!

Patience, hard work, not trying to game the SEs at the expense of the user experience and good content.

Other than that, there really aren't any proven strategies (unless you listen to the get-rich-quick types who will sell you any line of BS you want for $29.95).

Keep in mind, youtube's domain alone was REGISTERED about a year and a half ago.
