Configure SEO metadata
Optimize your documentation’s search visibility and social media presence by configuring SEO metadata at the page or site level. Properly configured metadata helps search engines understand your content and creates compelling previews when your pages are shared on social platforms.
When configuring SEO metadata, ensure your titles and descriptions are unique, descriptive, and relevant to the page content. Keep descriptions between 150-160 characters for optimal display in search results.
