Questions and answers

SEO Table of Contents & jump-link questions

How does a Table of Contents help On-Page SEO and AI Search?

A semantic HTML <nav> Table of Contents paired with matching id='...' attributes on your H2 and H3 headings allows Google to display clickable 'Jump to' sitelinks directly in SERP snippets and gives AI answer engines a clear structural map of your article.

Why is it important to inject id attributes into the headings too?

An anchor link like <a href='#step-1'> only scrolls to the section if the corresponding heading actually carries id='step-1'. Our tab #2 ('Full HTML + Injected IDs') automatically writes the matching id attributes into every H2–H4 tag.

How are duplicate heading names handled?

If two subheadings share the exact same text (such as 'Examples'), the generator automatically appends a unique suffix (#examples and #examples-2) so your HTML stays valid.

Does the generated HTML Table of Contents require JavaScript?

No. It uses pure semantic HTML (<nav>, <ol>/<ul>, <li>, and <a href='#slug'>) so it works with zero client-side JavaScript and zero Cumulative Layout Shift (CLS).
