Facebook doesn't need to be open in a tab for it to know it was you on that site, and you don't even need to be signed in. You and your computers are connected, even if you think you are careful. If you have ever signed into FB from home, they know that machine / ip / whatever fingerprint is you. Even after you sign out, its still out. Even if you are in ingocnito mode, its still probably you. Then you sign in to FB…
However, I did some searches over the weekend on my iPhone, Safari in private mode, not logged in.
Back home, opened the macbook, did some search with an incognito browser window. And Google told me: You are in another city X, based on your browser history (!).
What?! Privacy is hard nowadays.

This is correct. Retargeting is one of the most valued aspects of adtech. Manufacturers website contains an iframe to the ad networks website. They signed up for this by placing JS snippet from the ad network on their site that created the iframe. This allows ad network to know that you've visited by placing cookie. Next time you visit site that shows ads from this network they can inspect cookie and show you the ret…
Although they wouldn't have used a cookie here since it is mentioned that different browsers & devices were used. It would mean that segmenting was done on the backend, maybe using a user id from a social network.

as someone who used to work for a targeted advertising co i can confirm that, overall, this is pretty accurate. And, nearly a decade ago we were doing work to connect fingerprint x and fingerprint y when they were actually the same person (usually on different computers or maybe in incognito). Conceptually it wasn't hard. People tend behave the same way regardless of what computer they're on. I'd be VERY surprised to…
I work on ads at Google. As far as I know we don't connect users who are not logged in out of piracy concern.
In other words, when you're signed out, ads can follow you around, but in the network it should seem like you are a different user from your signed-in version. This way, signing out has a consequence.
There are so many ways: - you opened a web page with a facebook's like button and facebook analyzed your browse history. If you browse for something in google shopping you might want to buy it, so facebook added it to your interests and showed an ad later to you. (Probably this was the cause) - google and facebook knows your location because you have a google/facebook app in your mobile. It is easy to know where you…
> you opened a web page with a facebook's like button and facebook analyzed your browse history How could facebook (or any website) access your browsing history? they know what link you access from their pages, but apart from that, can they get any info from the browser?
But there are ways to get information of you browse history:
with a facebook like button (other facebook library, or google analytics), which it is in almost all websites, you have the previous web.
There were bugs before in browsers that exposed the previous history (sorry I cannot find the link)
You could have an extension in your browser that analyzes the whole history.
You can also get information by opening an iframe and accessing other site cookies.
Doing history sniffing (although unlikely)

There is nothing else close, there is no google facebook microsoft in France.
I was going to suggest OVH, but looking at the reviews at glassdoor.com… well, maybe not. https://www.glassdoor.com/Reviews/OVH-Reviews-E523060.htm
OVH is only a hosting company. Low margin business. They have no software side, they don't make billion of dollars, they don't run thousands of projects.
You can (or at least could) absolutely target individuals with Facebook ads. Check out this prank: https://ghostinfluence.com/the-ultimate-retaliation-pranking...
