· My understanding is that with outdoor advertising it is a form of advertisement that you see outside of your own home so an example of this would be a billboard advertisement because this is advertisement that you would see outside. On the other hand, online advertisement is a form of advertisement that you can only see with the use of the internet. One example of online advertisement would be an advert on a website or on social media which are two common methods. Online advertisement is different from outdoor advertisement because it can be shared with other people via social media and sharing link. Online advertisements are easier to see because they can be seen on most websites.
