In the old days, newspapers and magazines knew that the more editorial breadth they had, the more readers they could seduce. Joe may read the section on cars, but Mary likes the lifestyle section. And Sanjay wants to know what’s happening abroad.But that’s no longer true for our digital world. Online, the more niche-appeal a site has, the more readers and the more likely they are to elicit paying subscribers.Education Week, a national B2B publication, has wisely adopted this philosophy for their audience of educational policy makers in different states and regions across the country.The site has chosen to tailor its newsletters and RSS feeds by publication, state, topic, and other niche areas. For example, you can get a newsletter called “Curriculum Matters” (the site smartly lets readers preview a sample at sign-up). Or you can get RSS feeds for educational topics related to your state, budget & finance, or bullying. Or perhaps you just want all the content from one blog — there’s an RSS feed for that.Of course, one should be careful about how fine one splices content. Education Week is a national publication with 30 years of archived content, so 100+ RSS feeds was do-able, even reasonable, for them. Other subscription sites may want to start off on a smaller scale, with three to five different offerings.
