This is a really article, I got some ideas from it. Steve Outing talked about paywall, and he gave some tips for paywall, and he thought paywall will only work in certain markets.
Here is some tips for protecting newspaper:
1. Offer paid subscriptions to the newspaper that also include free access to a digital-replica edition.
2. Offer paid digital-replica edition subscriptions that mimic the paper in electronic form, for those second-home owners in the area and others who want to keep up with...news and developments and prefer not to receive the print edition by mail when the news is several days old.
3. Continue to keep all your Web site content -- including locally produced news -- free to all. And yes, that includes print subscribers who might be tempted to save money, cancel the print edition, and rely on the free Web site.
4. Have your Web manager focus on better ad targeting, in order to identify out-of-area users as potential tourists interested in hotels, camping, excursions, etc. and show them relevant ads.
5. Most importantly, devise other reasons for paying print and/or digital subscribers to keep paying -- primarily by value-added online, digital, mobile and even physical extras not available to non-paying users of the Web site.
