Since you arent getting any helpful answers Ill jump in here. When companies want to advertise through online sources they can pick which groups they want to target. But there is a lot of data out there so you have to choose how much you want to drill down because every time you go down a level you are cutting out a lot of potential customers. Also while websites have your browsing data many only offer it in generic terms. When the company purchased this add they probably selected it to be showed to people who have shown interests in football SEC Cruise beach vacation.
Remember, its not people compiling this data on you, its computer algorithms. It sees you looking at game results for UT BAMA or reading a statement from a BAMA recruit that UT targeted or watching a video or a Saban freak out or him and Kiffin arguing. The algorithm sees you have an interest in BAMA but it isnt assigning it a positive or negative association. So even if the add placers had put Bama in their criteria it may not have removed you
