From Alan Murray, the Wall Street Journal's executive editor, come five ideas he feels offer the best options for charging for online content.
1. You need a mix of free and premium.
2. Don't think you can charge for exclusive content if it will be available elsewhere.
3. Don't charge for the most popular content.
4. Charge for niche material.
5. The narrower the niche, the better your chances of charging.
