Probably not coincidence. We are being tracked.
Companies such as Google look through the internet to try to find ways to link you to all of the devices you own and all of the accounts you have. Once they have that info, they use it place targeted ads.

Earlier this year a business associate and I were discussing a project over the phone. We have a regular relationship, and communicate periodically by email. He followed up on our discussions with an email, advising me that the client had authorized us to proceed.
But his email didn't come in at my business address that we use. It appeared in a Yahoo mail account that I use strictly for personal reasons, and particularly it's the account I use when I think there's a good chance that providing my email is going to result in large amounts of low priority mail. I often go for a week without visiting that account.
My associate and I have never communicated using that account, and he would have no way of even knowing that account is in my name.
We deduced that he had recently obtained a new iPhone, and in creating/migrating his contacts, Apple had added account data that it had obtained for people in his contacts list. So it recognized my name, had my name linked to the Yahoo email account, and so added that Yahoo mail address to his contact list. Then Apple made that Yahoo address the primary email address for my contact info., so when he sent me an email from his phone, it went to that Yahoo address.
BTW - I have never owned an Apple computer, nor an Apple device of any kind, nor have I ever used any Apple service such as iTunes. I have done zero business in my life and have never communicated with anyone. Yet Apple knew who I was and had me linked to at least one email account.
And the only way they could have made the connection is because they are scraping the internet and using the data to make those connections.
