Best ways to promote a website?

Can anybody with expierience tell me what are some ways to get good quality traffic to a website? what are some good ppc services besides google. Got kicked off of google and dont know why. Didnt do anything wrong. but anyways, there has to be other ppc that actually gets good traffic and not garbage traffic. Im open to new tactice that i may have not thought of as well. Anyone?

when I first did when I got into seo, was spamming social bookmarking sites. Mybloglog is a great site. First make your profile pic of some cute girl, and give yourself a girls name. Then start joining communities, and requesting random friends. Then create a basic comment to leave for people and asks them to check out your site and join your community because you have joined theirs. Make sure to have a spot where u can replace the persons name and website each time. Its not to hard to start getting 100 uniques a day with this. Mybloglog is just for blogs, but the same applies to other sites. This will also build up one way backlinks.
