Buying Popunders vs Tweets?
 

Which is better and why? This would be for non-targeted general views..

Anyone have some words of wisdom?

buy and test, then post your results here?

Test both of them to see what works better.

tweets, as you get true visitors, popunders are people who dont want to be on your site, more of a force, tweets are people that are willing.

why not go both ways and see which gives you better results.
