How is SEO changing to support microdata like Schema.org? And why is this metadata good for information retrieval and organic search engine optimization?

In this introductory guest lecture for the University of Washington, I present some of the problems in information retrieval for unstructured content ("blobs") and how to solve for these challenges using Schema.org microdata to define "entities".

There's a simple Schema.org markup exercise to expose students to the basics as well as jokes about horror movies, The Simpsons, Keanu Reeves, and even Joss Whedon just to keep things light-hearted and fun.

  • Thanks Jonathon, I'm searching for how to mark up / what to call an embedded Slideshare object. MediaObject > ImageObject is how you'd classify it, I'm guessing. (Slideshow?) - Allen

SEO in the Age of Entities: Using Schema.org for Findability SEO in the Age of Entities: Using Schema.org for Findability Presentation Transcript

  • INFO 498: Content Strategy (week #7)From Blobs to Structured DataSEO in the Age of Entities Jonathon Colman, @jcolman In-House SEO for REI www.REI.com
  • What is content? If you boil away all the formatting, what’s left? Just text? If so, then why isn’t full text search good enough to find what you’re looking for? What could work better than that? Any what can we do to content to support its findability?
  • http://www.youtube.com/watch?v=dsA4FnwrR7E
  • Huh? Wikipedia is a source?https://www.facebook.com/pages/The-Bus-That-Couldnt-Slow-Down/114241625259749
  • Oh, it’s via a synonym redirect to…http://en.wikipedia.org/w/index.php?title=The_Bus_Tha t_Couldn%27t_Slow_Down&redirect=no
  • Joss Whedon was a co-writer? WTF?!http://en.wikipedia.org/wiki/Speed_(1994_film)
  • What is a document? How can you tell what a document is about? How can you tell one document from another? What sort of signals do documents give us that help us derive their meaning? Do you know them when you see them?

  • The Problem with Blobs Unstructured content is useful, but only to a point It’s hard to scan, skim, and easily make sense of – both for humans and robots It’s hard to search against, particularly in a crowded collection with lots of competing content containing similar information What should a search engine pay attention to in order to help the user?
  • HTML metadata Metadata is “data about data”, right? In HTML, we can express metadata like:  <title>The Problem With Blobs</title>  <meta name=“description” content=“An overview of why blobs are tricky things to deal with.” />  <meta name="keywords" content=“blob, entity, seo, content strategy, inf0498" /> Unfortunately, that’s not going to be good enough. But why not? Let’s see…
  • 2.2M results! Where are the movies?
  • How can we do better?Real metadata – in this case, “microdata”.
  • What is Schema.org? Microdata standard agreed upon by Google, Bing, and Yahoo Uses relatively simple on-page code to turn blobs of content into structured data Once structured, this content become interoperable in other systems – you can display that data wherever the standards are accepted Here’s an example…
  • This can increase clicks by +30%.
  • Controlled entities help searchers Documents can be documents, authors can be authors, products can be products, and prices can be prices.  Each of these entities has a definition in Schema.org and markup that you can use to define a blob as being actual data. So if Homer doesn’t know the name of the movie “Speed”, he can still find it with searches for its subject, the actors, the year it came out, the director, etc.
  • Exercise: Use the “Article” schema Go to http://schema.org/Article Look at the entities and the code sample at the bottom Pick appropriate content from the IAI Library, such as http://iainstitute.org/en/learn/research/a _simplified_model_for_facet_analysis.php “View Source” and try marking it up with Schema.org microdata
  • Partial potential results<div itemscope itemtype=“http://schema.org/Article”> <h1 itemprop="name">A Simplified Model for Facet Analysis</h1> <div itemscope itemtype=“http://schema.org/Author”> <h2 itemprop=“name">Dr. Louise Spiteri</h2><br /> <spanitemprop=“URL">http://dal.academia.edu/LouiseSpiteri</span><br> <div itemscope itemtype=“http://schema.org/Affiliation”> Faculty of Management<br /> School of Library and Information Studies<br /> <span itemprop=“Organization”>Dalhousie University</span><br /> <div itemscope itemtype="schema.org/PostalAddress"> <span itemprop=“addressLocality”>Halifax</span><br /> <span itemprop="addressRegion">Nova Scotia</span> <spanitemprop="postalCode">NS B3H 3J5</span><br /> <span itemprop="addressCountry">Canada</span></div><br /> Voice: <span itemprop=“telephone”>(902) 494-2473</span><br /> Fax: <span itemprop=“faxNumber”>(902) 494-2451</span></div><br /> </div></div>
  • How to testUse Google’s Rich Snippets Testing Tool:http://www.google.com/webmasters/tools/richsnippets
  • Sample test output For this example blog post: http://homebiss.blogspot.com/2011/11/markup- blogger-schemaorg-examples.html The Google Rich Snippets Testing Tool shows this output, which includes some use of Schema.org: http://www.google.com/webmasters/tools/richsnip pets?url=http%3A%2F%2Fhomebiss.blogspot.com% 2F2011%2F11%2Fmarkup-blogger-schemaorg- examples.html&view=
  • What did we just learn? Schema.org is frakkin’ verbose. Entities can cascade poly-hierarchically There are many “right” approaches Not all entities need to be expressed Not all entities provide value Still, it’s hard to know when to stop  In your case, you’re done when the quarter’s over. 
  • Common Schema.org entities Thing > Person Thing > Organization Thing > CreativeWork > Article See also: Blog, BlogPosting, NewsArticle, ScholarlyArticle Thing > CreativeWork > MediaObject See also: AudioObject, ImageObject, VideoObject Thing > Place See full list at http://schema.org/docs/full.html
  • Constraints to consider Helping more people find more things is great, right? But in the Real World™:  Assume that there’s a cost to do this  Assume that there’s a cost for maintenance  Assume that the standards will change  Assume that there are other priorities  Assume that conflicts, dependencies exist
  • Takeaways Jon likes horror movies and The Simpsons Blobs aren’t evil, just misunderstood! Structured data entities help define blobs  Structured data entities make blobs easier to understand, learn from, index, and find  Metadata, microdata, and other methods can be used to create these entities SEO standards (such as Schema.org) are emerging to support entities in popular search engines.
