What This Means

The text content of the <h1> element, after stripping HTML, exceeds 70 characters. This is a notice-level check — the heading is functional, but its length may reduce its effectiveness as a topic signal.

Why It Matters for SEO

Search engines weight H1 text for topical relevance. A concise, focused H1 ("Complete Guide to On-Page SEO" at 34 characters) sends a clear signal. A very long H1 ("A Comprehensive, Detailed and Complete Guide to Everything You Need to Know About On-Page SEO Optimization in 2025") sends a diffuse one — the text is too long to be a strong, precise topic identifier.

For users, long H1s also scan poorly. The H1 is meant to be the first thing a visitor reads to confirm they are on the right page. A heading that runs to two or three lines requires more cognitive effort than a crisp one-liner.

What the Platform Checks

The platform strips HTML from the H1 element's text content and measures the character count. Fires when any H1 on the page exceeds 70 characters.

How to Fix It

Trim the H1 to a concise, focused phrase — ideally under 60 characters. Move supporting context into the subheading or opening paragraph:

  • Identify the core topic in 3-6 words and lead with that.
  • Remove qualifiers like "A Comprehensive Guide to" and "Everything You Need to Know About".
  • If the long H1 contains a subtitle, split it into H1 + H2.
  • Retain your primary keyword in the H1 but let the body copy handle the depth.

A useful test: cover the heading after the first 60 characters. Does the visible portion still communicate the page's primary topic? If not, restructure to lead with the topic.
