Sometimes it is hard for people to understand exactly how you can track website visitors and eventually associate their actions with a known person. KissMetrics does a great job of showing how all the magic works in an infographic I linked to below. This will also help you understand why content marketers love signup forms.
The basics of how to track website visitors and identify them:
- Associate every visitor with an anonymous ID
- Use Call To Actions (CTAs) to get them to give you their email address or name
- newsletter signups
- eBook downloads
- Free Demos
- etc.
- Link their anonymous ID to their contact info they just gave you
- If they visit again from a new device give them a new anonymous ID and eventually relate it to their profile once they login/execute another CTA
