A visible physical address builds user trust (especially for e-commerce and YMYL sites), supports local SEO rankings, and is a requirement for compliance in many jurisdictions.
Check the contact page and footer for a visible physical address. Verify the address is complete (street, city, state/region, postal code, country). Check whether the address uses the <address> HTML element and whether it is backed by LocalBusiness or PostalAddress schema markup.
Add the complete physical address to the footer and contact page. Wrap it in an <address> HTML element. Ensure the address exactly matches the address in your LocalBusiness JSON-LD schema and your Google Business Profile.
Displaying a physical address confirms to users and search engines that a business exists at a real location. For local SEO, the on-page address must match the address in Google Business Profile and LocalBusiness schema — inconsistencies reduce Google's confidence in the data and suppress local rankings.
Check the contact page and footer for visible address text. Verify the address includes: street number and name, city, state/region, postal code, and country. Check for <address> HTML element semantic wrapper. Cross-reference the visible address against any LocalBusiness JSON-LD schema address fields — they must match exactly. Flag if no address is found on either contact page or footer.
