This was happening to me until I removed Facebook and Facebook Messenger from my phone. I believe these apps listen to conversations even when you aren’t using them. I am not alone in believing this.

That is unreasonable conspiratorial thinking. Please don't believe it.

A totally plausible explanation for this (as plausible as any Amazon Echo passive speech recognition ad targeting theory) is that she's been seeing these ads for weeks, but they were completely irrelevant and her mind filtered them out until she happened to have house hunting / martial arts movies on her mind after these events.

This seems to be the most plausible, if least satisfying explanation.

I have worked for a number of ad tech companies over the years.

If this really is happening (and it seems possible it could be coincidence) the most likely explanation is cross device targeting using IP address.

So, most ad tech companies do cross device targeting, using device maps bought from other companies (Drawbridge being one). These companies attempt to assign a variety of devices from the same person to a single advertising profile. The simplest way they do this is by IP address. So if they have an IP address with a small number of devices, they decide it is probably a household and assign all those devices to the same advertising profile.

So, by being on the same wifi together (either at your place or hers) they will show ads on her devices based on your behavior (and vice versa).

The other explanations are possible, but I think this is the most likely

Nice try Mark.

Jokes aside, these issues are happening way too often for it to just be a coincidence. I've seen multiple friends and strangers, as well as myself, reporting that they were talking about something and then an ad shows up about that.

The Facebook app tracks location and other peoples' locations, and makes assumptions based on people being at the same place at the same time. If Facebook (or whoever) knows that several other people are all interested in new houses, and all those people + your girlfriend go to the same place(s), Facebook decides that your girlfriend might have the same interest as all those other people.

> Is this what the Internet is like for "regular" people? If so, holy shit. I'm glad I use uBlock Origin on my computers and an iPhone. Somewhere, in a dark corner in a AWS datacenter in Oregon, some third-party tracking software records "Hey, the only user within five-mile radius that blocks our ad links just finished watching a kung fu movie."

If you're going to get fingerprinted anyway, might as well save the bandwidth.

Of course, I have nothing against saving bandwidth. I just didn't expect to see an iPhone user non-ironically calling Android users as "regular people" these days. What year is it now? :P

My guess would be: 1) Facebook (ie instagram) knows you are in a relationship 2) Facebook knows girlfriend's location from being signed in (on Instagram) 3) Facebook knows locations are at open houses from data gathered from other users or around the web. Or maybe Facebook knows that going to a few totally new random residential locations in a short period of time, combined with girlfriend's other engagement activiti…

Not just with facebook, there are more options:

You can geofence users (probably the realtor does it) and then send targeted ads to audiences that touch more than one geofenced area.

For the kung-fu panda and martial arts. Do you share wifi and (public) ip addresses with your girlfirend?

This is a well-known psychological phenomenon, not a joke or coincidence.
