  1. Open Graph image description

    Describe the sharing image with og:image:alt.

  2. Structured data syntax

    Provide JSON-LD with @context and @type (or a typed @graph). Match the markup to the visible content; syntax alone does not validate its meaning.

  3. Distinct page titles

    Use a title that describes the purpose of this page rather than repeating the same title across URLs.
