So, what is Schema ?

A direct quote from provides a collection of shared vocabularies webmasters can use to mark up their pages in ways that can be understood by the major search engines: Google, Microsoft, Yandex and Yahoo!
Simply put - Schema is a set of rules in the form of HTML markup which are being collaboratively defined by search engine giants so that they can be standardized. There is a separate set of Schema definition for Articles, Products, Person, Movie and many others. Check out for more details. Let us quickly check out a simple schema for a blog / article:

<article itemscope itemtype="" class="article_content">
<h1 itemprop="name" class="article_title">Article Title Goes here</h1>
<p itemprop="description">A long but short description goes here ....</p>
<span itemprop="datePublished" content="2014-12-30"> 30 December, 2014 </span>
- authored by <h4><a rel="author" href="/member/profile/1/pankaj-pal">
<span itemprop="author" itemscope itemtype="">
<span itemprop="name">Pankaj Pal</span>
<a itemprop="url" href="/articles/view/71/Special-variables-in-Perl-with-examples">Read full article </a>

The highlighted snippet in the above HTML code is the markup we are interested in. Although self-explanatory, few schema attributes need explanation:

  • itemscope: used with container HTML element which contains all the information related to that entity - in our case it is the HTML element - <article>
  • itemtype: defines the type of an item in the form of a url, e.g. defines the specific schema and its properties for Articles.
  • itemprop: used to markup a particular property of an item. e.g. itemprop="name" marks the name of the article, itemprop="datePublished" marks the date when the article was published. Generally the value for itemprop will be picked up according to the HTML element, e.g. value of href if used with <a> element, value of src if used with '<img>' element. However, at times itemprop attributes may require value e.g. itemprop="datePublished" requires the date in a specific format and needs to be provided with content attribute within the same HTML element.
Note: We can have nested items too, e.g. in above example item - Article contains yet another item - Person which is nothing but the item that is used to denote the author of this article.
