Depending on how you sent them to the casino/poker site it can affect the sign up ratio. If you told them about a great bonus, but maybe didn’t explain the terms surrounding the bonus, they might not deposit the money. If they get to the site and are turned off by the look-and-feel they might look elsewhere. There are many other examples, but you the idea. 40 downloads could result in a deposit, but not for certain, it also depends on what you are marketing, casino or poker. For instance, a lot of people download poker software, but then only play at free tables, then a few weeks or months later after they are comfortable with the game play, they might open up a real money account.
