Itemtype and itemid
Start an Article markup with itemscope and itemtype.
What are itemscope and itemtype?
Adding Schema.org structured data rests on two attributes. itemscope says an element starts a scope. itemtype gives that element a type as a URL.
When marking up an article you add both to the article tag:
<article itemscope itemtype="https://schema.org/Article">The itemtype value is always a Schema.org URL. The Article type fits news, opinion pieces and blog posts.
What is itemid?
The itemid attribute gives the marked element a unique identifier. The value is a URL and should point to the article itself.
For example, if the article lives at /articles/education-in-the-ai-era, you put that into itemid. Search engines can then match copies of the same article across places.
itemid always appears together with itemscope and itemtype.
Exercise Add itemscope, itemtype and itemid to the article tag
Take the article skeleton from the previous lesson. Add itemscope, itemtype="https://schema.org/Article" and itemid attributes to the <article> tag.
For itemid, use the article's URL path: /articles/education-in-the-ai-era.
