community to create, maintain and

object belongs to. This is typically set to
https://schema.org
● Itemtype is the schema object, which can
either be a Thing or DataType
● Properties are the attributes of an Itemtype

-----------------Itemtypes are Schema Objects.
All Itemtypes are derived of Thing,
except DataTypes.
The syntax of Item Types
is in Pascal Case
(aka Upper Camel Case)
There a 9 sub-types of Thing which
all types except Data Types.
DataTypes are things like Text,
Boolean, URL etc.

Properties
Properties are part of Item Types.
They help classify properties of an
Itemtype in a structured nature
● Properties have Expected Types that
they may passthrough.
○ Typically this will be either a
subtype of Thing or a Data Type
● Properties are in camelCase,
specifically lower camel case.
● Properties that accept an Item Type that
is a sub type of Thing can be an object
● The Expected Type of an object can
also be a Super Type or Sub Type of the
Expected Type.
● Sub Types may gain specific properties
for it and its children that differ from the
Super Type

By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
Expected Types
● Typically this will be either a subtype of Thing
or a Data Type
● Expected Types may still validate with a Sub
Type of Super Type
○ e.g. Expected Type of LocalBusiness
can be a Pharmacist
○ e.g. Expected type of ListElement can
be a Thing
● Expected Types may have some mandatory
fields beyond name or id when validating for
Google Search Enhancements
By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
Sub Types
● Subtypes inherit properties from their parent
● Subtypes may have multiple Super Types that
it can inherit properties from.
○ e.g. a Pharmacy can inherit properties
from Thing, Organization, Place,
MedicalOrganization, and LocalBusiness
○ e.g. a Pharmacy can be a SubType of
either a MedicalBusiness or
MedicalOrganization

Nesting Item Types
● Item Types have properties that are expected
to be other Item Types
● The nesting of some Item Types are flexible
and can have each other as expect types.
○ e.g. a Product can reference Offer via the
property offers
○ An Offer can reference Product via the
property itemOffered

By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
Multiple Item Types
● Google recommends using JSON-LD in
particular for nested items and multiple items
● In JSON-LD, multiple Item Types can be placed
in an array by square brackets.
● Many Sub Types of Intangible such as
Enumeration and ItemList are designed to
handle a list of items.
By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
Enumeration &
Data Types
● Data Types handle basic data types such as
integers, strings, booleans etc.
○ e.g. Text, URL, XPathType, cssSelector,
Date, Number, Boolean, True, False etc.
○ Data Types may be subject to standards,
such as ISO 8601 for Date, or Unicode for
Numbers
● Enumeration members can be set to specific
canonical Schema.org items
○ E.g. The property of availability in an
Offer can equal an Enumeration such as
https://schema.org/InStock
By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
Handling Multiple
Schema Objects
● By default, Google will define all detected
schema objects as part of a WebPage
○ This prevents conflicts within the context
of the page.
○ Use mainEntityOfPage to explicitly label
the main entity of these schema objects
○ Multiple Schema Objects of the same
type will be treated as an array.
By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
WebPage and Specific
Web Page Types
● WebPage is the explicit object a valid HTML
page will be read as - no schema needed.
● Has the mainContentOfPage property, which
sets the primary content of the page using
cssSelector or xpath
● Has 10 Sub Types for specific Web Page types
● Works well with the mainEnitity property to
explicitly define the main schema object
i.e. mainEntity of Product for an ItemPage
○ AboutPage
○ CheckoutPage
○ CollectionPage
○ ContactPage
○ FAQPage
WebPage and Specific
Web Page Types
● Has the primaryImageOfPage property to set
the image most representative of the page.
● Has the significantLink property, which sets
most important URL of the page. For multiple
URLs, use significantLinks. Non-navigational
● Sub Types are:
By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
○ ItemPage
○ MedicalWebPage
○ ProfilePage
○ QAPage
○ SearchResultsPage

Debugging Structured Data
By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
https://search.google.com/structured-data/testing-tool/
Structured Data is about providing context to
content and data.
It is more important they know that this Thing is
a Place than it is a Village.
Don’t Manually Over Optimise, it is not scalable,
prone to error and difficult to change as
standards evolve.
Use Source Data to populate Structured Data
when possible. Use Plugins like Yoast or
Modules like schema.org when non-technical.
Don’t Overthink Structured Data
By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019

  • 16. Itemscope, Context Itemtype & Properties ● Itemscope specifies the block of HTML code is an itemtype for RDFa & Microdata ● Context in JSON-LD sets the schema the object belongs to. This is typically set to https://schema.org ● Itemtype is the schema object, which can either be a Thing or DataType ● Properties are the attributes of an Itemtype By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
  • 17. Item Types Thing name: Text description: Text url: URL sameAs: URL potentialAction: Action image: ImageObject or Image mainEntityOfPage: URL subjectOf: CreativeWork or Event Identifier: PropertyValue or Text or URL MedicalEntity properties from thing ----------------- Organization properties from thing ----------------- CreativeWork properties from thing ----------------- Event properties from thing ----------------- Intangible properties from thing ----------------- Action properties from thing ----------------- Place properties from thing ----------------- Person properties from thing ----------------- Product properties from thing -----------------Itemtypes are Schema Objects. All Itemtypes are derived of Thing, except DataTypes. The syntax of Item Types is in Pascal Case (aka Upper Camel Case) There a 9 sub-types of Thing which all types except Data Types. DataTypes are things like Text, Boolean, URL etc.

  • 20. Properties Properties are part of Item Types. They help classify properties of an Itemtype in a structured nature ● Properties have Expected Types that they may passthrough. ○ Typically this will be either a subtype of Thing or a Data Type ● Properties are in camelCase, specifically lower camel case. ● Properties that accept an Item Type that is a sub type of Thing can be an object ● The Expected Type of an object can also be a Super Type or Sub Type of the Expected Type. ● Sub Types may gain specific properties for it and its children that differ from the Super Type By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019

The property of availability in an Offer can equal an Enumeration such as https://schema.org/InStock
  • 33. By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019 Handling Multiple Schema Objects ● By default, Google will define all detected schema objects as part of a WebPage ○ This prevents conflicts within the context of the page. ○ Use mainEntityOfPage to explicitly label the main entity of these schema objects ○ Multiple Schema Objects of the same type will be treated as an array.

  • 43. Debugging Structured Data By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
  • 45. Structured Data is about providing context to content and data. It is more important they know that this Thing is a Place than it is a Village. Don’t Manually Over Optimise, it is not scalable, prone to error and difficult to change as standards evolve. Use Source Data to populate Structured Data when possible. Use Plugins like Yoast or Modules like schema.org when non-technical. Don’t Overthink Structured Data By Peter Macinkovic, Digital Marketing ManagerSEO Melbourne Meetup | April 2019
