How to assess engagement/the value of a visitor to the business?

Use Google Analytics to assess engagement/the value of a visitor to your business!!

1. No web metric, or combination of metrics, can discriminate between kind of engagement i.e. positive engagement. This requires primary research.
2. All web metrics can do is discriminate between relative degrees of engagement.
3. Basic metrics can only discriminate between low degrees of engagement.
4. A customer with a high score in his visit metrics may nevertheless feel apathetic towards the brand.
