Why Structured Data?
• Gives meaning to strings of letters • Establishes relationships between objects • Helps in decision making
Analytics/Search-Friendly Sites
• Almost everything happens after users login
• Each user categorizes themselves (sex, age, country, political views, etc)
• Actions categorized (upload photo, change status, use application etc…)
Analytics/Search-Friendly Sites
• Number of views, comments, favorites help identify popular videos
• Percent viewed of video determine stickiness
• Tags determine content categorization
Analytics/Search-Friendly Sites
• Sales of items• Reviews (and the
number of reviews) • Ratings
How Do You Extract Meaning From This Text?
I live in Dubai, United Arab Emirates. I work at XYZ Inc. which sells products and services.
You Tag it with “Microformats”
I live in<div class="adr"> <span class="locality">Dubai,</span>
<span class="country-name">United Arab Emirates</span>
</div>I work at <div class="org">XYZ Inc.</div> which
sells products and services.
It’s much easier to make sense of the text
• “Dubai” is now a locality• “United Arab Emirates” is a country• “XYZ Inc.” is an organization
Relationships
• Link to other people in a “meaningful” way• Embed information about the linked person to
inform the site / search engine
hCard
• Similar to vCards
What users see
What search engines and other sites see
The Result
• Snippets of meta data about search results, make it easier for users to decide
Conclusion
3 extra minutes of tagging an article can potentially multiply its effect, reach, and importance
