What the analyzer checks

1️⃣

H1 count

Confirms exactly one H1 is present. Flags pages with zero H1s (missed keyword opportunity) or multiple H1s (topic confusion).

📐

Hierarchy order

Detects skipped heading levels (e.g. H1 → H3 without H2) that indicate structural problems or heading-as-styling abuse.

⬜

Empty headings

Finds headings with no text content — invisible to users but confusing for crawlers and screen readers.

🔑

Keyword in H1

Checks whether your target keyword appears in the H1 — one of the strongest on-page SEO signals still respected by Google.

🌲

Visual tree

Renders all headings as an indented tree so you can instantly see the document outline and spot structural problems.

📊

Heading stats

Total heading count by level (H1: 1, H2: 4, H3: 8…) to catch content with too few headings (wall of text) or over-sectioned content.

Frequently asked questions

Why is heading structure important for SEO?

Headings (H1–H6) help search engines understand the structure and topic hierarchy of your content. The H1 signals the main topic and should include your primary keyword. H2–H6 headings organise subtopics and provide additional keyword signals. Proper heading structure also improves accessibility for screen reader users.

Should a page have exactly one H1?

Yes, best practice is one H1 per page. Multiple H1s were acceptable in HTML5 sectioning contexts, but Google recommends a single H1. Zero H1s is a missed opportunity to reinforce your primary keyword. Multiple H1s can dilute the primary topic signal.

What is a heading hierarchy and why does it matter?

Heading hierarchy means using headings in order: H1 → H2 → H3, without skipping levels. Proper hierarchy helps search engines understand content structure and matters for accessibility — screen readers navigate pages by heading level. Skipped levels often indicate styling abuse rather than genuine structural organisation.

Should the H1 match the page title tag?

They should be closely aligned but don't need to be identical. The title tag appears in the SERP and browser tab; the H1 is what users see on the page. Having very different H1 and title can confuse both users and search engines. Use the same core keyword in both, varying the wording slightly.
