I am thinking of Press Release and article submission because it carves a permanent place on internet. Then pay per post, but in pay per post thing, top blogs will charge a lot of money. My other option is Email marketing. My thought on PPC is that it comes and goes, yeah it does gives traffic but google can take away my $2500 in one hour if i go for it, so i don't want PPC for now. What i need is a steady permanent traffic. Also i might outsource link building job which can give me backlinks and traffic. Other than these, what can guarantee me some serious members to the service?
