We have been using their services for about 5 years now and it has always worked well with our site so far. I would say they are very professional in terms of customer service as we often get emails from them when there's any issues or questions regarding how to use their products. Their support team also does not hesitate to answer all queries promptly even if its during off hours (or early morning). Sometimes you may receive some error messages which might be difficult to resolve but overall everything works great! They do charge quite high cost compared to other companies out here like us. So try first before making your final decision. It helps since i know what they offer beforehand. The benefits include having better targeted ads to increase revenue; being able to serve more relevant advertisements to users and advertisers alike by collecting data through cookies, user IDs, IP addresses, geolocation information, device type/browser info, time zones, social network profiles, search engine activity along.
