Design Festival has a lovely article on how to add Rich Snippet in WP.
Google is providing a host of (relatively) new features that allow you to add “rich snippet” metadata to your web content. For those who design, write, and manage WordPress blogs, this is a powerful tool that can help you build your personal brand much more efficiently — the reason being that Google will display your author information in search results if you’ve properly labeled your metadata via the rich snippets markup!
What Are Rich Snippets?
Normally, HTML markup is used for displaying content in a web browser. “Rich snippets” are a format of HTML that allow you to carefully define pieces of information within a web page so that search engines and other programs know what the heck the data is good for.
Using Rich Snippets, we can tell search engines who I am using code like this:
<p>Hi there! My name is <span itemprop=”name”>Tara Hornor</span>! Nice to meet you.</p>
You can define scores of items like logos, birthdays, product IDs, and much, much more. But, today I’m really only interested in me…or at least my standing as an author, so that my picture shows up prominently in Google search results.
What will Rich Snippets do for SEO?
Rich Snippets have the potential to generate more and better quality traffic to any website. As the use of Rich Snippets spreads across the web, search page results will no longer consist of a simple optimised title and meta description. They will increasingly show more information to help users make better decisions on the sites they visit.
