My little rant on search engine optimization firm
Some search engine optimization services also offer link optimization, finding web sites to post links on that relate with your product. Your designer clothing site may be a really popular link from a web site that sells hand bags. It focuses on how a network of sites will interact positively with each other. There is also pay per click advertising. If you are worried about paying money for something that you are not sure is working, this would be a great option for you.
