I will say that I have not made one red cent in the IM niche. Use the product launches like OAC to build your list and thats about it. Write articles and send ppl to your squeeze page since google makes you do a lot of stupid stuff with adwords or they will slap your entire account and have editors breathing down your neck every time you start a new campaign...trust me this is what im going through right now. Once they start slapping you they will slap everything even campaigns that have been running for weeks....ppl make Adwords friendly squeeze pages but it is not worth the risk and besides you will not get a good opt-in rate because they force you to add links and a bunch of content and blah, blah, blah...i am tired of them...but with articles you can send them anywhere you want and do it your way and get their names and then redirect them to some kind of review for the product in question....this way you can build your list even though you probably wont make any sales (you might, but probably not) then when you get that fat list promote those new launches that are in the low price range by just shooting an email to your list and don't waste a ton of time. In other niches make newsletters and reviews...you can use adwords to send them to a review where they have the option to opt-in to your list (just send traffic to blogger or something)...this will get you a few opt-tins for free because you will be making sales to off-set the cost of Adwords and hopefully turn a profit in the process...also again write articles and send ppl to a squeeze page to expediate the list building process and provide them with USEFUL content and slip a sale in here and there...thats what i do. hope that helps someone.
