What are Blogger Pages?
Blogger Pages lets you publish static information in a stand alone page in your blog, that is, your page will not be included in the series of posts you made and displayed in your homepage. Instead, pages will be given separate links in your sidebar or as tabs on top of your blog whichever way you choose it to be displayed. (As of this writing you can add up to 10 pages in your blog.) There are a lot of information you can add in your pages, and that depends on your needs, but most of the time, published in static pages are About Us page, Privacy Policy Page, Terms of Use Page etc.
