Just out of curiosity, I was monitoring my traffic today...
I went to pornhub.com but saw that at least 30-40 additional request to different porn-related sites were made.
Usually I get redirected once or so from the actual site. This was kinda interesting to me...
1. do all the other request really come from pornhub ?
2. if so, what is the reason behind this ? If it's purely marketing, I don't see the point really - as the end user will only be redirected once, maybe couple of times.
3. or is it only showing the sources of all the adverts and additional content from the site ?
I apologize for using a porn site as an example, but this is the only time I've noticed something like this happening.
