Yeah true. I guest it's whatever floats your boat. I typically just like to go after the weak keywords & built myself up over time. I might attempt on tackling a medium competition keyword & try to do something fancy with it, but you get the point. Screw the high competition ones. I think the main thing is to just provide relevant information that people need to do. Perhaps you could even put Adsense units on the information part of your site within the pages, and then put up products. Just try not to annoy people with adsense all over the place or slow down your website, which would in turn slow down your site.

Then for talking about positives and negatives, I think that's highly important. If you sound lop sided or very salesy, people not going to want to buy from your site. They'll think you're another weirdo trying to scam them out of there money. ;) If people see you are willing to talk about a few negatives to a certain product, they'll be more willing to hand over the money since that'll create an atmosphere of understanding rather than trying to "grab and take".

Like for example: I advertise a certain product & I talk to them how great it is, then I simply put the affiliate link. Well, how much does the product cost? If they visit the site & find out it's like $300 without knowing in advance, I know I'd be like WOW and then probably leave. I like to know about something 1st before I go somewhere. I don't like to see surprises or things I wasn't prepared for.

Good advice.
