Ranking for which keyword can make me most $$$ ?
 

Alright,

After success of many medium sized SEO campaigns I am looking to launch relatively bigger project. I need your opinions for that ...

According to you, which keyword can get me most $$$ if I can get ranked in top5 on all the three major search engines.

At the moment, I am considering:

1) penis enlargement
2) adult dating

I have not finalized yet, and open to the suggestions and opinions. So, what keyword you dream to get ranked for? hey, don't tell me 'sex' or 'porn' ... I want to generate targeted traffic not looking for bulk and junk looking for free tgps and so ...
also, they are full of strong competitors like hell .. :disgust

mainstream keywords will get you 5000X the money, why waste time trying to get #1 for something adult?

finance
mobile
travel
medical (not penis enlargement)

Exactly. But mainstream guys end-up as stronger competitors than adult ones. It'd be easier to get ranked for adult terms than the mainstream ones for the keywords having same KEI.
