We needed an effective way to track incoming sales inquiries via Adwords and other digital marketing campaigns (email, etc). Although there are other more in-depth systems out there that allow a huge amount of integration in overall marketing strategies, we felt that Calltracker.io was much more suitable to our program of rapid, evolving media tests. With integrations to G-Analytics it's really all that's required to spin up call tracking quickly, test placements, evaluate results, and move forward. We'll continue to use the product moving forward. Review collected by and hosted on G2.com.
