Penulis Create Open Graph in Blogger Blogspot for SEO to boost your blog's visibility in Search Engine like Google and Bing.
Put the following two codes in your Blogger Template (Template -> Edit HTML)
First Code: xmlns:og='http://ogp.me/ns#'
Put the above code right after the following code [http://www.google.com/2005/gml/expr'] at the top of the template. It will look like this:
<html xmlns='http://www.w3.org/1999/xhtml' xmlns:b='http://www.google.com/2005/gml/b' xmlns:data='http://www.google.com/2005/gml/data' xmlns:expr='http://www.google.com/2005/gml/expr' xmlns:og='http://ogp.me/ns#'>
