How is content marketing measured?

Content marketing is measured in a variety of ways, but the four most important are:

1. Consumption – how many people read, viewed or watched your content? For example:  Google analytics page views, YouTube watches, Slideshare downloads, etc.
2. Sharing – how many people have shared your content? How many people have mentioned it?
3. Leads generated – how many content visitors converted into leads?
4. Sales made – how many content visitors converted into customers?
