much of my original traffic came from posting in adult-oriented forums, search engine stuff, a link trade or two, and a handful of directories. whatever you do, do not, i repeat, do not put your links on any directory with less than a PR 3, as it will likely damage you in the long run.
for instance, on one very popular adult forum, i managed to get ahold of an account with over 3000+ posts...this will work great for free backlinks that will bring literally tons of traffic. simply put in the signature of the account a link and some basic info, along with some(possibly hidden
) text with keywords and such. that helps make big g and the other SE's believe it's totally in tune with the context of the threads, which in turn gives a +1 back link to your site, and a vote for PR for that thread.
