Getting the feed for a particular label in Blogger is much harder than it should be. Really, Blogger should just give them to us, but instead, they send us to help documents that may not help. To make it even better, just because your label feeds use to work, they may no longer work as I found out the other day for a client. I did my research and here is how you can get your own label feeds on Blogger blogs.
If you have a Blogspot blog:
Just be sure to change blogname to match your blog. The labelname is what appears in the URL of your blog label page.
Example URL: http://googleblog.blogspot.com/search/label/personalization
Example Feed: http://googleblog.blogspot.com/feeds/posts/default/-/personalization
If you host your own blog:
The trick here is that you need to find your blog id. To do this, login to your Blogger dashboard and click on the new post link. In the URL bar your blog ID will show up and it’ll look something like this:
Example URL: http://www.yourblog.com/label/personalization
Example Feed: http://www2.blogger.com/feeds/1234567980123456789/posts/default/-/personalization
If you have spaces in your label, your feed URL would look like the following.
Example URL: http://googleblog.blogspot.com/search/label/policy%20and%20issues
Example Feed: http://googleblog.blogspot.com/feeds/posts/default/-/policy%20and%20issues
Example URL: http://www.yourblog.com/label/policy%20and%20issues
Example Feed: http://www2.blogger.com/feeds/1234567980123456789/posts/default/-/policy%20and%20issues
Yes, there is one requirement and that is that feeds are enabled for your blog. It should go without saying, but I thought I’d share.
