How to Fix Multiple H1 Tags

Use one h1 per page so the document outline and the page's subject are unambiguous.

Easy Medium Impact 30 min

Multiple h1 tags on a page leave the document without a single top-level heading, which weakens the outline screen readers navigate by and blurs what the page is about. HTML5 technically permits several, but one h1 naming the page's subject, with h2s beneath it, is the structure that works for both readers and search engines.

Why It Matters

The h1 is the strongest structural signal about a page's subject. Three of them means three candidate subjects, and a screen-reader user navigating by heading level gets three tops with no hierarchy between them.

How to Fix

1

Count them

Check how many h1 elements the page renders. They are often introduced unintentionally — a logo wrapped in an h1 in the header, plus the real page title.
2

Keep the one that names the page

The h1 should be the page's own subject, not the site name. The logo belongs in a link, not a heading.
3

Demote the rest

Convert the others to h2 or h3 according to their place in the hierarchy. Style them however you like — the level is structure, not size.
4

Check the resulting outline

Read the headings in order. They should describe the page like a table of contents, with no skipped levels.

Platform-Specific Instructions

WordPress

Many themes wrap the site title in an h1 on every page. The setting is usually in the theme's header template or customiser.

Next.js

Check shared layout components — a heading in a layout renders on every page that uses it, alongside each page's own h1.

Fixed that one.
