Breadcrumbs makes the user navigation more easy, and not for SEO. But now Google algorithm is efficient to parse those Breadcrumb links and it will reflect in the Google search result. I think you might notice this kind of search results with breadcrumbs or else check the screen shot of a search result. And its a new thing for me because I was not yet involved in the optimization of my site. So you will get more visits now.

Ok, lets come to the point. Google suggested to use the following format to identify the breadcrumbs more easily. Here I’m using the simplest version of the format but you can find more here. By just adding some xmlns and typeof will gives you the better result.

<div xmlns:v="http://rdf.data-vocabulary.org/#" class="breadcrumb">
	<span typeof="v:Breadcrumb">
	<a rel="v:url" property="v:title" href="http://articles.tutorboy.com">Home</a>
	</span>
	&rsaquo;
	<span typeof="v:Breadcrumb">
		<a rel="v:url" property="v:title" href="http://articles.tutorboy.com/category/twitter/">Twitter</a>
	</span>
	&rsaquo;
	<span typeof="v:Breadcrumb">
		<a rel="v:url" property="v:title" href="http://articles.tutorboy.com/topics/bookmarklet/">Bookmarklet</a>
	</span>
	&rsaquo;
	<span typeof="v:Breadcrumb">
		<a rel="v:url" property="v:title" href="http://articles.tutorboy.com/topics/twitter/">Twitter</a>
	</span>
</div>

So the output of the above format will be like below.
