I used to assume the Google Opinion Rewards question “which of the following places have you visited recently” was largely about refining their mapping data, since they regularly assume I’m in a place that I’m just walking past.
But what if it’s about testing how good your memory is? They know the last time I was at Canadian Tire, so what if this is not just about refining location mapping, but about how long it takes me to forget about a
place I’ve spent money at visit to a potential advertiser.
Feed that back into the advertising profile they have of me, and Google could start suggesting to advertisers how soon after a visit to their store I should be targeted with an ad to reinforce their brand.
