Question 1

What is the difference between JSON-LD and Microdata?

Accepted Answer

JSON-LD and Microdata are both formats for structured data, but JSON-LD is Google's recommended approach. JSON-LD is placed in a single script tag in your page's head section and doesn't require changes to your HTML markup. Microdata, on the other hand, is woven into your HTML elements with special attributes, making it harder to maintain.

Question 2

Which schema types are most important for SEO?

Accepted Answer

The most impactful schema types depend on your content. FAQ schema can generate expandable answers directly in search results. Article schema helps Google understand news and blog content. Product schema enables price and availability display. LocalBusiness schema powers local pack results. Start with the type that matches your primary content.

Question 3

How do I validate my structured data?

Accepted Answer

After generating your JSON-LD with this tool, test it with Google's Rich Results Test (search.google.com/test/rich-results) to see if your markup qualifies for rich results. You can also use Schema.org's validator for syntax checking. Both tools are free and will identify any errors in your markup.

Question 4

Where do I place the JSON-LD script tag?

Accepted Answer

Google recommends placing JSON-LD in the head section of your HTML document, wrapped in a script tag with type application/ld+json. However, Google can also read JSON-LD from the body. For best results and clean code organisation, place it in the head.

Question 5

Can I have multiple schema types on one page?

Accepted Answer

Yes. You can include multiple JSON-LD script blocks on a single page. For example, a product page might have Product schema, BreadcrumbList schema, and FAQ schema. Each should be in its own script tag. Google will read all of them.
