I want post title then meta description for my each post content dynamically for blogspot in html.
You can post title and Meta description for your blogspot by putting Meta tags in your blogger. This is done by logging into your blogger and go to the "Dashboard" and select "Template". Click on "Edit Html" and make the appropriate changes. Go to http://www.haakblog.com/2013/06/add-seo-meta-tags-title-description-keywords-blogger.html for more.
