Frequently asked questions
Does schema markup guarantee a rich result?
No. Valid markup can establish eligibility, but search engines decide whether a feature is useful for a query.
Is JSON-LD preferred?
It is often easiest to maintain because it stays separate from layout markup, while still describing visible page information.
Can I add review stars to my own company page?
Do not add self-serving review markup merely to seek stars. Follow the current eligibility and content policies for the specific feature.
