I have started to invest in themes and plugins to make the sites better. I have bought the WP robot, video jackpot, RSS pro poster. These are so far very good in my opinion since google seems to love youtube videos and I can post amazon reviews with the WP robot. Any suggestions on other paid plugins that may make a positive difference? Thanks

WPtouch Pro - is a great plugin to make your site Mobile Optimized and give the visitors that are using mobile devices mobile optimized pages. On the plugin you can put ads that only visitors using mobile device will see (regular visitors will see different ads) and increase your revenue.
