I have started a news blog about four month ago. And I have daily 200 - 300 visitors. Most of them through search engine. But I can't get many RSS feed subscribers through this. The page per visit is about 2.7. So, its not that bad (I hope). But I hardly get 3-4 subscribers everyday. (So far I have about 250). Is there a way to get more subscribers through this visitors? My email subscribers have about 35% of unverified ones. (I use feedburner). Is it possible that the activation email from feedburner is going to spam folder and that is why people do not activate. How to improve on both the RSS and email subscribers?
