One of the most disappointing features of an outbound marketing is the measurability. You will only throw a lot of money for a print ad campaign hoping that you will be able to grab the attention of the readers, cross fingers that they will be your target audience, and count on every lucky star that they will actually reach on your sales team.
A lot of clients are presenting this challenge whenever they look for help in finding for a marketing partner. These people feel like they have been wasting their money and only struggle on identifying how their marketing spends result in revenue in their organization. This part is exactly where the inbound marketing conversion starts.
