Semantic web

Semantic web:

  1. A   proposed   development of the World Wide Web in which data in web pages is structured and tagged in such a way that it can be read directly by computers.

Following  are  the ways   which are  doing  these......

Schema.org Structured Data

Schema.org (often called Schema) is a specific vocabulary of tags (or microdata) that you can add to your HTML to improve the way your page is represented in SERPs.

Code Sample

<div itemscope itemtype="https://schema.org/Book">
  <span itemprop="name"> Inbound Marketing and SEO: Insights from the Moz Blog</span>
  <span itemprop="author">Rand Fishkin</span>
</div>

What is Schema.org Structured Data?

Schema.org is the result of collaboration between Google, Bing, Yandex, and Yahoo! to help you provide the information their search engines need to understand your content and provide the best search results possible at this time. Adding Schema markup to your HTML improves the way your page displays in SERPs by enhancing the rich snippets that are displayed beneath the page title.
We  can  Markup  our web page content in three ways  to Structure our data onf web page:
(1)Microdata     (Learn About Microdata  )
(2) RDFa      (Learn About RDFa  )
(3)  JSON-LD   (Learn About  JSON-LD  )


To know more about  schema  Markup example using microdata :


see given  code example  without  schema  markup  for  Video :

<html>
<body>

<iframe width="560height="315src="https://www.youtube.com/embed/DjqO-stAfk0" frameborder="0allowfullscreen></iframe>

</body>
</html>
Note:  above    <iframe > html tag  is only link the youtube video  but it is not  understandable  by   Search Engine like google ,bing ,yahoo etc.

Now  see  code  example with   Video Schema Markup example which is understandable to search engine :


<html>
<body>
<div itemprop="video" itemscope itemtype="http://schema.org/VideoObject">
<h2>Video: <span itemprop="name">JiFi 3 complete speed test</span></h2>
<meta itemprop="duration" content="2:55" />
<meta itemprop="thumbnailUrl" content="https://i.ytimg.com/vi/DjqO-stAfk0/1.jpg?time=1495877884957" />
<meta itemprop="contentURL" content="https://youtu.be/DjqO-stAfk0" />
<meta itemprop="uploadDate" content="March 12, 2017 4:55 PM" />
<meta itemprop="expires" content="2012-01-30T19:00:00+08:00" />

<meta itemprop="width" content="400" />
<meta itemprop="description" content="jio fi wireless router">
