In this marketing approach, you try to push a message by displaying an ad to a potential customer without them showing interest first. These are ads before the video on YouTube, banners, and pop-ups on websites or any other unwanted display of your product or service. It is a very traditional way of marketing and often used because it is cheaper than the pull alternative. On the other hand, it is considered interruptive so many internet users develop something called “banner blindness” where they intentionally ignore anything that looks like an add.
