Now imagine you had that brochure on your website instead. You can measure exactly how many people viewed the page where it's hosted, and you can collect the contact details of those who download it by using forms. Not only can you measure how many people are engaging with your content, but you're also generating qualified leads when people download it.

If you're a clothing brand, these might take the form of photos of how other people styled a shirt or dress, pulled from a branded hashtag where people can contribute.
