I have been pitched Xvin on multiple occasions and have asked quite a few questions without ever getting a clear answer. Their presentation clearly shows Autotrader and other 3rd party sites as where they grab "clickstream" data. When I asked how they capture that data, I was told this was "their proprietary technology," which I know is not the case. However, any direct questions they are unable or unwilling to answer, which is obviously by design.
Things I have picked up on:
Programmatic Display product (does not include social, even though it is pictured)
Not sold on CPM basis (this is my biggest complaint, it is extremely overpriced for a display product).
Captures search intent data and/or auto intenders
They still use Google UA - GA4 numbers vary drastically
They claim "assists", which in reality mean nothing. On 4 store account ($3k each), the traffic lead to 0 lead form conversions. While the campaigns generate a lot of website traffic, I really question why they never result in a lead form conversion. The lack of transparency really bothers me. I should add that I worked at iheart for 9 years until 2019 and have previous experience with iheart automotive digital products.
