What is Itemscope?
“I’ve got something to say!”

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
What is Itemtype?
Now that you have everyone’s attention…
“Okay, I want to talk about _______.”

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
What is Itemprop?
All the details about what you just said you’d be
talking about.
“And another thing!”
You can (and will) use many itemprops.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
What is Itemprop?
These are specific data points
about the thing (itemtype) you’re talking about.

@SEMpdx
#SearchFest
@mike_arnesen

What is Itemprop?
Many itemprops appear across all itemtypes.

What are Embedded Entities?
Itemscopes within itemprops!

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
An Event entity is declared with an itemtype.
A PostalAddress entity is, too.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
An Event entity has a location itemprop
which should be an PostalAddress.
The value of the parent entity’s itemprop
is another entity embedded within in.

Implementation
That’s all well and good,
but how do we do it?

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Finding Your Schema
Use schema.org/docs/schemas.html

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Finding Your Schema
A) Use “Full List of Types”
B) Find a good starting point and
drill down as much as required

@SEMpdx

Pro Tips
● More is better - except hidden text
● Pay attention to “Text” vs. “Expected Types”
● Test with multiple tools

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
No Hidden Text
Don’t apply semantic
markup to text that’s not
visible to users.
When it’s okay:
Dates/times
Implicit information
References to entities

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Text vs. Expected Types
Some itemprops can just be text.
Some itemprops must refer to other itemtypes(entities).

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Test with Multiple Tools
Structured Data Testing Tool
https://developers.google.com/structured-data/testing-tool/
Structured Data Linter
http://linter.structured-data.org/

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Overcoming Common Issues
Microdata (aka, inline markup)
is restrictive and breaks easily.
It’s not uncommon for information
to be in different locations on the page.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Enter Itemref & Itemid
Bringing us all together

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Itemref & Itemid
These tools allow you to bridge the gap
between <divs>, structures, and even pages and websites.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Itemref
Reference data points to use as properties
in your main entity.
Itemid
Link to other identified entities as properties for
to your main entity.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Using Itemref
TL;DR - Create an independent “data blob” that you can
refer to from your main entity using itemref.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Using Itemref
1) Wrap a <span> or <div> around your data to form your
data blob. Give it an itemscope but not an itemtype.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Using Itemref
2) Markup the data you want to reference using an
itemprop, just like it was part of your main entity.
Give it a unique id as well.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Using Itemref
3) On your main entity, add an itemref attribute to the main
itemscope and itemtype declaration. Specify the unique id
that you gave your “data blob”

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Using Itemid
TL;DR - Give a whole entity a unique identifier that you can
link to in order to fill out a property.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Using Itemid
1) Markup the entity like normal. Start with itemscope and
itemtype and then get into the specific itemprops.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Using Itemid
2) Add itemid with a fragment identifier.

@SEMpdx
#SearchFest
@mike_arnesen
upbuild.io
Using Itemid
3) Within your main entity, include a <link> tag.
Specify both the itemprop that the entity will relate to and
the fragment identifier.
