In many Blogger templates there is a “subscribe to: Posts (Atom)” link, so that the blog visitors can subscribe to the Atom feeds. Considering the fact that many readers use RSS for their blog feeds, many of you could find this link pretty useless. Moreover it occupies space at the bottom of the template and it doesn’t look nice at all. In this case you might want to remove it.
Step 1. Go to your Dashboard > Template > Edit HTML (click on Proceed button if needed)
Step 2. Select “Expand Widget Templates”
Step 3. Find (CTRL + F) this line:
<b:include data='feedLinks' name='feedLinksBody'/
Step 4. Remove it and Save Template.
This should remove subscribe to: posts (atom) link.
