Page titles tell search engines what pages are about. They appear in search results. Good titles attract clicks. Missing titles hurt visibility. Titles should be 30 to 60 characters long.

Meta descriptions summarize page content. They appear below titles in search results. Good descriptions increase clicks. Missing descriptions reduce clicks. Descriptions should be 120 to 160 characters long.

H1 headings mark main page topics. They help search engines understand content. Pages should have exactly one H1. Multiple H1s confuse search engines. Missing H1s reduce topical clarity.
