Google webmasters tool is the first choice of every blogger in order to maintain a good ranking in search engines. The way we see a web page is not the way search engine bot see it, a search engine bot never knows - the title of a post or a post publishing date - and for the indexing schema.org documentation is required.
Before proceeding let me tell you something about schema.org, it is a markup scheme launched by Google, Yahoo! and Bing in 2011 introduce some more benefits of search engine and their working.
All you need to do is to go to Google Webmasters and click on Search Appearances, in drop-down click Data Highlighter. Now click on start tagging and enter your blog post URL and select Article in drop-down menu.
Then the page URL you've entered before will be opened and all you need to do is to highlight all the stuff listed on right sidebar. Just highlight and select which element of blog post/ article it points to.
