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…)
