I offer both text links and download links and sometimes a flash link.
Then I have a pop up window on some pages that briefly explains the download process that visitors can click.
The reason is the installer is not named after the casino in many cases and this may scare some visitors.
I’ve tested many download links and they’ll register a d/l even if it is not a complete download, that is if the visitor just clicks the link and doesn’t actually download the installer file. RTG inparticular.
It was my understanding that Casino Coins also shows unique downloads which are completed downloads.
However almost all my conversions come via text links.
