An advertising intermediary delivers ads from various advertisers to its network of partnering websites. It notices a large increase in clicks on ads relating to one advertiser, and uses data regarding the source of the clicks to determine that 80% of the clicks come from bots rather than humans.

Clicking on a link in an article might normally send you to another page or part of the article. To achieve this, 1°) your browser sends a request to a server linked to the website, 2°) the server answers back (“here is the article you asked for”), using technical information automatically included in the request sent by your device, to properly display the information / images that are part of the article you asked for. Technically, such exchange of information is necessary to deliver the content that appears on your screen.

You visited an online retailer website from your computer to look at mystery books and you consented to your data being used to create profiles for personalised advertising. If you later browse on your phone using the same Wifi, a vendor may infer you have been using both devices and you may be presented with an ad about the same mystery books in the mobile app you are using, but only if you have consented to receiving personalised advertising on this app.

When you see an ad in your weather forecast app, some technical details that your device always transmits when accessing the Internet (such as the IP address of your Wifi and the version of your device’s operating system) can be used for instance to limit the number of times you see the same ad in other apps.
