In your opinion, Which PPC platform have better conversions?
Should I invest more money in Facebook ads, Adwords, Adroll, AdMob or any other platform you think have better conversions and can get me more out of my limited campaign money.
If you have limited budget for Digital marketing , then I think you should invest on Social Media to make presence and get Fans for your Social Media Profiles ( Facebook, LinkedIn, Twitter and Youtube). Because once you got Fans & Followers you can market your products or services for FREE in Future :)
Adroll is a re targeting platform. If you have budget you can use it. The conversion depends on your ad , Content or services on your website and feedback from your past customers.
