If anything they’d be buying since they’re the ones presenting ads… The whole data selling discussion online is always ridiculous. Who are these mystical data buyers ready to shell out billions for crappy “data” (does anyone participating in these discussions actually have a definition of what they think this ridiculously non specific ““data”” even is?) to present slightly better ads to users? Why would Google sell this data, shouldn’t they want to keep it to themselves?
selling your data refers to people buying ads and being like I want to show my dog food ad to 100,000 people who have a dog, and then Google only shows the ad to people who have a dog
I know of a SaaS company that charges for their products to end users for a monthly fee. They make significantly more money selling the data of their users to 3rd parties than they do from subscriptions. Also, they figured this out after the fact, it wasn’t a core business component when they launched, but they still ended up raising the monthly fees due to “inflation”.
