What is Table of Contents?
Anchor-linked section lists that improve navigation, earn sitelinks, and expose heading structure to parsers. Auto-generate from H2/H3 IDs rather than hand-maintaining.

Heading Hierarchy
The nested H1→H2→H3 outline of a page. A clean hierarchy lets readers scan and lets parsers chunk sections accurately for retrieval and snippets.
Passage Ranking
Ranking a page based on one strong section even when the whole page covers more. Self-contained sections with clear headings can win queries the page was never explicitly "about".
Internal Link
A link between pages on the same site, guiding discovery and distributing relevance. Controlled tests show deliberate internal-link changes lifting organic traffic 5–25%, and underlinked priority pages are a standard audit finding.
On-Page SEO
Optimizing individual pages: titles, headings, content depth, internal links, images, and schema. On-page work decides relevance once technical SEO has made the page reachable.
Title Tag
The clickable headline in search results and the strongest on-page relevance signal. Google rewrites most titles, so clarity and completeness beat rigid length rules.
Meta Description
The optional summary that can become the result snippet. Absence is not a penalty and Google rewrites most descriptions, so prioritize valuable pages where controlled wording earns clicks.
