Note: To knw your Blog Id, First, sign in to Blogger. Then choose the blog whose ID you want to find, and click on its name.
From any of the posting, settings, or template pages, you can find your blog’s ID number if you look at the URL in the address bar. At the end of the address, you can see that it says blogID=XXXXXX where the X’s represent your blog’s ID.
