The eye view is very useful tool, it helps us understand our audience better than other platforms like google analytics or facebook insights etc., It also gives us an idea of what percentage we are reaching out in market which help me decide my budget accordingly. I have not found anything dislike about this product so far as everything looks good but if you want something new then go with Google Analytics because there's lot things available over here including heatmap feature too. We use these tools for customer engagement campaigns such as retargeting ads using AdWords platform. This allows us to reach customers who were interested previously by showing them relevant content again via email/text messages sent through DoubleClick Campaign Manager (DCCM).
