Aggregator tools are great for following your favorite blogs and managing what content might be most important for you to explore further. If a visitor knows how to find an RSS blog feed, then it's easy for him to add his blog to his aggregator. However, many visitors are not tech savvy and may not be able to figure out how to find a feed. Will they be disappointed and not return to your blog again?
It's easy to add auto-discovery code your blog pages to facilitate feed subscription. To accomplish this, just add this code within the <head>section of your site HTML code:
<link rel=”alternate” type=”application/rss+xml” title=”Your Title” href=”http://yourdomain.com/yourfeed” />
With this code, any auto-discovery tool can find this code and allow for easy addition of the blog feed. If your blog offers multiple feeds for different formats or different categories, this code can be repeated for each feed.
Good luck and happy blogging!
