John Gruber talks about RSS and Ad revenue.
If you’ve got a model where revenue is tied only to web page views, switching to full-content RSS feeds will hurt, at least in the short term. The problem, I say, isn’t with full-content RSS feeds, but rather with a business model that hinges solely on web page views. The precious commodity that we, as publishers, have to offer advertisers is the attention of our readers. Web page views are a terribly inaccurate, if not outright misleading, metric for attention. Subscribers to a full-content RSS feed are among the readers paying the most attention, but generate among the least web page views.
A reader asking for a full-content RSS feed is a reader who wants to pay more attention to what you publish. There have to be ways to thrive financially from that.
I never had to worry about revenue because I don’t have Ads on this site. I don’t ever plan to have Ads because it’s a personal site. I want to focus on the last sentence I quoted. I get very annoyed with blogs that don’t have full-content RSS. They force me to jump out of my RSS reader. This is especially annoying if I’m reading on iPhone with bad signal.
When I designed this blog, I had readability and the overall reading experience in mind. This isn’t just for when people are reading on the site, but also when reading through RSS. Offer people the full feed, because they’re the ones who care.
