I use Schema.org as a clarification layer, not as a ranking trick. The markup should describe what genuinely exists on the page.

What structured data helps with

It can identify a person or company, describe an article, service, product or breadcrumb trail, and connect multiple pages to the same entity. That reduces ambiguity for machines interpreting the site.

Useful types for a professional website

  • Person or Organization for identity.
  • WebSite and WebPage for page context.
  • Article for editorial content.
  • BreadcrumbList for hierarchy.
  • Service or Product only when the page genuinely represents that offer.

Common mistakes

Do not invent ratings, mark up reviews that are not visible, create contradictory entities or add every schema type available. Consistency matters more than quantity.

Why this also matters for GEO

GEO depends on much more than schema, but clear entity relationships support machine understanding. The strongest combination remains useful content, consistent identity, credible sources and direct answers.

I can check whether your markup clarifies the site or simply adds noise.
