I made a small FB game last year and I checked it back yesterday. I thought can I use it to collect emails by running it with PPC ads on FB. The emails will be collected with the app email permission. I ran PPC for this game last year in July-August just to get a taste of FB PPC. But I thought it today for collecting email. I have 2 questions- 1) Is it a good idea to get emails with an app. Can I expect good conversion from them for CPA offers in game/movie niche (please suggest if I can target other niches as well to them) or do it the old way of creating FB pages targeted to a niche and get leads from there. 2) In particular to this game, can I get friend invites within the game (I mean would people find it worth to share this to their friends) to get maximum installs. I know that this game doesn't provide much of a gameplay. Can anybody take the pain to help me out and suggest some viral effect to it, so that I don't only get install with ads. Currently it posts high score to your wall and allow you to invite friends within the game. The game is here. It is a fly swatting game with 5 levels and simple gameplay. The game name is in Hindi, but gameplay is in English. I can change the logo and name to english if it is worth. Code: hxxp://apps.facebook.com/maakhi-maar If it can work then I have to get a SSL certificate for my site to allow it to be compatible with secure browsing feature in FB. Currently it displays a warning for secure browsing if you try to play it via https instead of http (you can neglect that though). Note: If you are paranoid about the permissions of this game then you can skip the "Post on Wall" permission, it won't make any posts to your wall and you can delete the app from Account Settings > Apps after you test it, or better you don't try it.
