How would you know whether that product's maker pays for that sort of marketing? Perhaps if you tried ten products and got one positive, that would suffice.
OK, we just made up a big fake conversation in the presence of a desktop and laptop running fb, an iphone running the ap, and an iphone only accessing via Safari.
We mentioned Target, including a request for upcoming sales and target credit cards, Advil, Colgate, Liquid Plumber, Scott toilet paper, Wells Fargo (though we need to rule that out bc my daughter's been googling them re DAPL), Citibank, Marriott, Red Lobster, and an imaginary pending trip to Maine.
10 hours later: nothing convincing. I got one for an Amex card and he got one for Discover, but nothing exact. His other ads were verizon, geico, halls, lay's, AT&T. Mine were only local news sites -- paper, radio and tv.
