A: The main advantage of RocketLink is no limit on clicks at all!
It means that all the great retargeting features will work even if your links go viral and drive a massive traffic :). The tool is made for that! It would be really sad if you got a million of clicks and could be able to retarget only 5% of them :-/
The Galaxy Plan offered on AppSumo allows you to store up to 50 different pixel codes in your account and generate up to 3000 links each month! But no limits on clicks!
Moreover, you can generate QR codes out of your links, place them on posters, signs, trucks, buses, subways or whatever will work for your business and retarget people who scan those :)
