Why SEO Matters

Frequently Asked Questions

What is schema markup?

Schema markup is code (usually JSON-LD) you add to your HTML that tells search engines and AI what your content means. For example, it tells Google "this is a product costing $49" rather than hoping Google figures it out from your page text.

Which schema types are most important?

For most businesses: Organization, LocalBusiness, Product/Service, FAQ, BreadcrumbList, and WebPage. The exact types depend on your business — our scanner recommends the right schemas for your content.

Does schema affect rankings directly?

Schema doesn't directly boost rankings but it enables rich results (which get more clicks) and helps AI models understand your content (which improves AEO/GEO). Indirectly, higher CTR from rich results signals relevance to Google.
