On: Inside a viral website

[glaucon]

The wikipedia article https://en.wikipedia.org/wiki/Online_advertising is a starting place. There is also a vast swag of stuff related to digital marketing here https://en.wikipedia.org/wiki/Category:Online_advertising but it will require significant digging to work out what's useful for your interest.

Also this part of the ads.google.com site https://ads.google.com/intl/en_NZ/home/resources/advanced/ has a reasonable amount of stuff within it but obviously only from a Google point of view. I don't suppose it matters but that's the NZ version of the page, probably only the 0800 number is specific to NZ but you might change en_NZ to whatever your language code is.
