(BW: This article concluded remarketing didn’t work for this product.)
If you go to Amazon and browse watches, you will suddenly notice a preponderance of watch ads everywhere you go on the Internet. This is ‘remarketing’ (also known as ‘retargeting’ or, more colloquially, ‘cyber stalking’). Wikipedia defines it as:
a form of online targeted advertising by which online advertising is targeted to consumers based on their previous Internet actions, in situations where these actions did not result in a sale or conversion.
a) It is hard work to get potential purchasers to visit your website
b) some 99% of visitors to a typical website leave without buying anything
It seems to make sense to spend some time and money reminding non-purchasers to come back to your website in the hope that they will eventually purchase.
