If you don’t have an RSS feed set up on your blog, you’re essentially asking people to remember to come back to check out new content. People are lazy and busy, and they’re not going to do that.
If you want more readers, make it simple by setting up a feed. You can get a free one at FeedBurner. Don’t worry; it’s not overly complicated. The system will walk you through the process, and in 5 minutes your readers will be able to get your latest blog post sent to their email or blog reader!
