Rich Snippets and Breadcrumbs Structure 19Aug, 2013

What are rich snippets?

In simple words rich snippets are designed for brief explanation of web-page content to make it easier for users to understand, what the page is about in search result. When considering, inheriting the advantages of rich-snippets, keep in mind that user would find your information helpful when

selecting from different search results.

Three different markup formats in which we can design rich-snippets data:-

1. Microdata
Microdata uses straight forward attributes in markup language tags (often) to assign transient and descriptive names to things and properties.

Microdata Consists of 3 elements:-
1. itemscope
2. itemtype
3. itemprop

HTML marked up with microdata example:-
<div itemscope itemtype=”http://schema.org/Product”>
<a itemprop=”url” href=”http://www.buysellteach.com/Product-Detail/39/Bubble-Gum-Balancing-Equations-Center”>
<div itemprop=”name”>
<strong>Bubble Gum Balancing Equations Center</strong>
</div>
</a>
<div itemprop=”brand” itemscope itemtype=”http://schema.org/Organization”>
<span itemprop=”name”>BuySellTeach</span></div>
<div itemprop=”aggregateRating” itemscope itemtype=”http://schema.org/AggregateRating”>
<span itemprop=”ratingValue”>4.0</span> based on <span itemprop=”reviewCount”>10</span> reviews</div>
<div itemprop=”offers” itemscope itemtype=”http://schema.org/Offer”><span itemprop=”price”>$4.00</span><link itemprop=”itemCondition” href=”http://schema.org/NewCondition” /> New</div></div>

Rich snippets – Breadcrumbs

A breadcrumb trail is a set of links (breadcrumbs) that can help a user understand and navigate your site’s hierarchy, like this:
Properties
Breadcrumbs can contain a number of different properties which can be labeled using microdata or RDFa markup. Google recognizes the following breadcrumb properties.

Property:-
Title : The title of a breadcrumb.
URL : The URL of a breadcrumb.
Child : The next breadcrumb in the hierarchy. The child must be another Breadcrumb item.

The following HTML code describes a breadcrumb trail for a product page on a kindergarten site.
<a href=”http://www.example.com/pre-k-K”>Pre K – K</a> ›
<a href=”http://www.example.com/pre-k-k/kindergarten”>Kindergarten</a> ›
<a href=”http://www.example.com/pre-k-k/kindergarten/language-arts”>Language Arts</a>

This set of breadcrumbs will appear on the page like this:
