if you have 500usd at adwords - where will you send the traffic for getting more results? To email/zip CPA submit? or to some clickbank product? or may be some another stuff? thanks
First off all you can't experiment a lot with just 500$,you'll burn that money really fast. Your best shoot is probably reviewing a clickbank product or sending your visitors to CPA offers. Don't link directly from adwords to the CPA or Clickbank landing page. TIP: Don't bid on broad terms because they are not usually money makers. So if you are,for an example, selling shoes don't bid on keywords like "red shoes" bid on keywords that will have probably a better conversion ratio like"nike running red shoes"....
I'd create a site with a poll (eg. Does Susan Boyle Need a Makeover?) and tell users that they will have the chance to win a INSERT_YOUR_CPA_OFFER_PRIZE_HERE if they vote. That's probably what I'd do with $500 in AdWords.
i agree with you guys that you will spend very fast 500usd at adwords if you will not concentrate at 1 offer. That's why i am more thinking about CPA offer or some clickbank.
