One method of helping new readers read more content from your blog is to add a “recent posts” widget to the sidebar. Blogger users can do this easily by adding a “feed widget” using the default feed URL (eg: http://yourblog.blogspot.com/feeds/posts/default). However, this will only return the 5 most recent posts at most; Blogger doesn’t (yet) support the ability to display a greater number of entries.
Use Feedburner’s BuzzBoost
To use BuzzBoost to add a recent posts widget to your Blogger sidebar, you must already use Feedburner to syndicate your Blogger feeds (here are four great reasons why Blogger users should do this). Then log into your Feedburner dashboard and select the blog for which you would like to activate BuzzBoost.
On this page, click on the “Publicize” tab which is near the top of the page, then look in the left sidebar to find the BuzzBoost link:
On the BuzzBoost page, you will see the many options you can use to configure your recent posts widget. These options are pretty self-explanatory, but the most important thing for you to do is activate your BuzzBoost widget by clicking on the appropriate button at the bottom of the page.
You could also choose to add this as a new widget in Blogger, which generates a simple widget installer and adds this automatically to your Blogger layout. This is by far the simplest method: simply choose Blogger from the options in the drop-down menu, and follow the prompts to add this to your layout.
