What is best for true mainstream traffic
 

What is the best methods for getting quality hits to mainstream sites (as in solid goods, nothing adult).

Porn is easy.

But mainstream is new for me.

With porn, its about just getting hits. With luck some will equal money (even if its simply selling trades).

But mainstream is different.

Its about getting people who want tour products, rather than simply looking at your site.

Is it all going to be seo and purchasing ad sense links? I could do this, but then it gets to the stage its cheaper to simply rent a shop out and get real customers, and could end up even cheaper.

It does not matter what many people say adwords is by far the best traffic you can get pound by pound, the thing is that you need to know your acquisition cost and the customer value, in adult because there is so much traffic you just keep puyshing more videos, links, in mainstream every cent counts.

Adwords all the way

This!
Just get your tracking properly set, use google analytics and set "goals" in there.
Coming from adult, tracking should be a walk in the park for you. :thumbsup

Best method is to built the website for users, not search engines.

If it is a product that a woman between 35-50 wants Pininterest is your friend
