I wanna introduce 2 free chrome extensions to help you do Facebook marketing better.
The fastest way to do Facebook marketing is to run Facebook Ads and I wanna suggest a FREE extension to make your ads more catchy (and even save costs): cool text maker
extension. It will create stylish & funny text to make your ads stand out from the crowd. I have tested it and the CTR of ads increased by 23%.
Another tool to let your fans (if you have fanpage) invite their friends to try your product is this: invite all friends facebook
extension. Create an event to launch or update of your app and tell your fan to use this tool to invite their friends to the events quickly.
