Alright, heres a "method" I use that makes you money basically guaranteed: (btw, this is quite blackhat, and I think most of the ppl know about this one)

This is as simple as hell, and takes almost no work. All you have to do is exploit adwords' free advertiseing credits and cheap vouchers you can buy at places like DP.

Go over to google and type in some highly searched keyword term right now. Type in something like "how to make money online" or "fat loss". Notice that the "Sponsored Links" pages are packed with ads. Alot of people (and most of them affiliates) want their own little 120 word message to be shown and seen. Their paying big bucks for those advertisements, and not because their feeling so gracious as to simply just tell the world of a nice little website (and how surpriseing > product too) that they think is sympathetic. Their paying big per click with the hopes of making a profit.

And alot of the ppl that do google-adword their ads, after the commissions (-) ppc investment equation outcome, end up making decent moolah. So if they can make profits in the end, after sending google upfront their cold-hard cash, paying for all ad costs in full, don't you think you can make some nice money by simple using googles' free advertiseing credits? You'd be a dumbass if you couldnt.
Even if you would execute a campaign that would theoretically make you only "break even" on your ppc cost vs. sales, youd still be in profit, because you got the advertiseing credits for far below what they were worth.

I have a friend who I buy $50 activated adwords accounts from for $6. So If I do is make a theoretical "break even" campaign, Im still $44 in profit, and remember, thats only if I break even. Not bad, knowing It only takes about 10 minutes to find some clickbank or other product I want to sell and write a 120 word ad in my adwords account.

There is a drawback of this method however. I want to warn you ahead of the time if this is new for you and you want to try this out.

Unfortunately, due to simple human nature, after you find out you can get so much under-real-cost adwords advertiseing, you start to get lazy and kinda careless. And you get lazy and careless really fast.

You end up not really careing about thinking too much of what the best ad message would be, you dont care about researching and finding the most profitable keywords/products/Max bid value combination, and you dont really take efforts to improveing your ads after they go up, let alone "tweak" them.

You find some catchy, probably popular clickbank ebook to promote, you just copy & paste in the adword ad they themselves provide you, and then you crank up the max bid to some sure-dominateing value like $3, $4 or even $5 per click max-bid, ensureing you'll definately get premium placement (although of course, you dont pay that much, you just pay a little higher then all the rest of the advertisers). And you know what? You dont care, since you know your going to be making profit in the end no matter what and so it doesnt really matter anyway. Even with top-end ppc bids, your still almost guaranteed to make a profit or at the very-very least, break (truely) even, since you bought $50 credits for only a measly $6.
Well at least, thats what happened to me. But Im making changes to that now.

So there you have it. Another surefire method for you guys on how to make some decent money online.
