Recently I was trying to understand Schema.org Markup. So writing this while discovering a wonderful SEO techniques. I will describe here in short about Schema.org Markup. Everything written here is collected from various websites across the internet. Google has introduced Schema.org in June 02, 2011.
It is a structured data markup schema supported by major search engines such as Google, Microsoft, Yahoo! and Yandex. It helps search engines to understand the information on webpages and provide better results. It is not actually a markup language or a protocol.
Schema.org is the attempt of search engines to make structured markup easier to understand for website owners and search crawlers.
You have used H1 tag. H1 tag means the browser will show the text in a Heading 1 format. But it does not give any information about the text. For example “Shemul” within H1 tag will display “Shemul” in h1 format. But what does it mean? Now the Schema.org markup will tell the browser and search engine that it is a “Person”. Microdata is a set of tags, introduced with HTML5, that allows you to do this.
Google Supports Three different standards for structured data markup: microdata, microformats, and RDFa. But Google has decided to focus on just one format for schema.org and that is microdata. Also a single format will improve consistency across search engines relying on the data. You have heard the name of Facebook Open Graph meta data and Twitter card. They are doing the same work as Schema.org. But less information provided by them. You can use Schema.org and social graph protocols together on one page.
Search engines like Google are using on-page markup to create rich snippets in search results. More information in Search results ensures more attention of visitors. The visitors also get benefited by absolute information.
Google doesn’t use markup for ranking purposes at this time—but rich snippets can make your web pages appear more prominently in search results, so you may see an increase in traffic.

How to Use schema.org
Getting Started guide on the schema.org site is the most useful way to learn schema.org. You can use the Google structured data testing tool to see what information Google can extract from your pages.
Google currently supports: rich snippets for
People: Rich snippet shows: organization, location, position/title
Events: Rich snippet shows: date, time and place
Reviews: Rich snippet shows: reviewer, average rating
Products: Rich snippet shows: price range, availability
Recipes:Rich snippet shows: cooking time, calories, ingredients
Google suggests that most elements of your schema.org markup is visible to the human being. That means use less meta tag. Also keep in ind that Google will NOT generate rich snippets for time-sensitive pages.

Schema.org Versus rel=”author”
Schema.org may override, replace or change your Authorship rich snippets.
With /videoObject Schema (in most cases), your headshot will be replaced by the video thumbnail image.
With /Review Schema, your headshot will be removed from the search engine.
If you have previously marked up content with Microdata, microformat or RDF, you don’t need to redo existing content in the new schema.org format. Although Google says: “Changing to the new markup format could be helpful over time because you will be switching to a standard that is accepted across all three companies”.
Itemscope is usually put within <div></div>
Itemprop may be put within any of the existing HTML tags (e.g. <h1>, <a>) or you can create new tags to put it in (e.g. <meta>, <span>, <time>, <link>)
