It is absolutely technologically possible that your digital trail indicates you are contemplating a RAV4 purchase and are concerned about dead batteries. Unless you are taking unusual and extraordinary measures, Facebook, Google, and other lesser-known data aggregators know this and have made it available to their advertisers, customers and partners. I would bet significant money that they even know you are looking at out of state dealers and which ones. The only question is: does a specific given site that you may happen to use have the sophistication to use that information and to what extent. Facebook, Google, Amazon, and the like have staggering levels of sophistication. I don't know about places like Edmunds but imagine they are not unsophisticated.
