Table of Contents

Glossary

A navigational element listing the sections of a long-form content piece with jump links.

Definition

A table of contents (TOC) is a structured list of the major sections or headings of a long-form piece of content, placed near the beginning, with each item typically linking directly to its section via an anchor link. On web pages, TOCs serve both as navigation aids for readers and as structural signals to search engines. Google frequently uses TOC links to generate site-link search results and jump-to sections in featured snippets.

Why It Matters

A table of contents significantly improves the user experience of long-form content by letting readers immediately understand the content structure and navigate to the section most relevant to their need. For SEO, TOCs improve dwell time, reduce bounce rate, and increase the probability of earning featured snippet placement.

Examples

Common Mistakes

Adding a table of contents to short articles where it's unnecessary.

Not using actual HTML anchor IDs on headings.

Making the TOC so long it is itself overwhelming.

Placing the TOC so far down the page that readers encounter content before seeing navigation.
