If you are Blogger user, have you set your Post Feed Footer link? The "Post Feed Footer" can be found on Settings -> Side Feed. It is a link that will appear after each post in your post feed. You must also set "Enable Post Pages" to "Yes" (in Archiving settings) and set "Allow Blog Feeds" to "Full".
Why add a Post Feed Footer? You probably do not know, but there could be a lot of websites that are republishing your RSS feeds, especially when your feeds are set to "Full". When Googlebot crawls the sites, it is very possible that it'll see the reprinted RSS feeds first before yours?
So let the search engine see your link by adding it at the end of your every blog feed.
Here is what you're gonna do. Add this on the "Post Feed Footer". Replace the link with your blog URL.
<hr /> <a href="http://www.myblog.com">My Blog Name</a>
Remember, for this to work, you should be syndicated in full feeds. Enjoy!
