RSS feeds are a great way to keep loyal readers up to date with your content, as well as to drive up traffic.
By providing an RSS feed for your readers, they will continuously get updates as you add content to your blog, and through RSS directories, new readers can find your content and check out your site.
If you don't already have an RSS feed, you can go to a website called feedburner.com and create one for your blog. You can add code for buttons which will allow a reader to add your blog's RSS feed. Then you can submit your RSS feed into RSS feed directories, thereby increasing the positive exposure of your blog and building your readership.
Once your readers have you on an RSS feed, it's up to you to provide quality content that your readers can automatically view and enjoy in real time!
