There are so many things to consider when working on SEO, I have done work for many sites by changing there entire SEO, the hardest ones are computer, gaming and health sites. I have worked on several hard sites including this viagra one and let me tell you it is very hard to rank these type of sites. The best tool in my opinion is the keyword tool at tools.seobook.com they provide a firefox plugin and keyword research tool better than the adwords one :)

Good luck
