Why Does My Website Skip Heading Levels? Heading Structure Explained for Small Business Websites
If your audit flagged "heading levels skip around," the page probably looks completely fine - this isn't something a visitor notices by eye. It's a gap in the invisible outline of your page, one that screen reader users and Google both rely on to make sense of your content.
What heading structure actually is
Every page has H1 through H6 tags, and used correctly they form an outline - the same idea as a document's table of contents. One H1 for the page title, H2s for the major sections underneath it, H3s for subsections inside those, and so on down the levels. That outline exists whether or not anyone can see it, and two very different audiences depend on it: screen readers build a navigable list from it, and search engines use it to figure out how your content is organized and which parts matter most.
What "skipping a level" means
A skipped level is a gap in that outline - an H1 followed directly by an H3 with no H2 in between, or an H2 followed directly by an H4. It almost always happens the same way: someone picked a heading tag because its default size and weight matched what they wanted a piece of text to look like, not because of where that text actually sits in the page's structure. A smaller "H3" happens to look right for a sub-headline, so it gets used, even though the section it's nested under never had its own H2.
<h1>Services</h1> ... <h3>Emergency Repairs</h3> - the H3 was chosen because it looked like the right size for a subheading, but there's no H2 above it. Anyone navigating by heading has no way to tell this belongs under "Services" at all.
<h1>Services</h1> ... <h2>Emergency Repairs</h2> - or, if it's genuinely a subsection of a larger service category, an H2 for the category and an H3 underneath it. The level always matches the real place in the outline; the visual size is a separate decision made with CSS.
Why it matters even though nothing looks broken
Screen reader users frequently navigate a page by jumping heading to heading, the same way a sighted visitor skims a page with their eyes before deciding where to actually read. A skipped level reads like a section vanished, or leaves someone unsure whether they're still inside the section they thought they were in - a real, disorienting gap in an experience the visual design never shows a sighted visitor. Google's crawler reads the same outline to understand how your content is organized and which headings carry the most weight, so a broken hierarchy is a weaker signal to both audiences from a single underlying cause.
The fix: separate structure from style
Heading level and font size are two different decisions, and the fix is treating them that way. Pick the heading tag that matches the content's actual place in the outline - H1 once per page, H2 for each major section, H3 for subsections inside those - then use CSS to make any of them look exactly the size and weight you want. An H3 can be styled to look identical to an H2 if that's the visual effect you're after; the tag itself should still reflect where it really sits in the structure, not how big you want the text.
How to check your own site
Open Chrome DevTools (F12 or right-click → Inspect), switch to the Elements panel, and search for h1 through h6 down the page in order - or install a free heading-outline browser extension that lists every heading on the page as a simple nested list in one click. If that list skips a number anywhere, that's the exact gap the free audit also flags automatically, naming exactly how many headings it found.

Frequently asked questions
What is heading structure on a website?
Heading structure is the outline your page's H1 through H6 tags form when read in order, the same way a document's table of contents works - one H1 for the page title, H2s for major sections, H3s for subsections inside those, and so on. Screen readers build a navigable outline from these tags, and search engines use the same outline to understand how your content is organized.
What does it mean to skip a heading level?
Skipping a level means jumping from an H1 straight to an H3 with no H2 in between, or from an H2 straight to an H4 - a gap in the outline where a level is missing entirely. This almost always happens because a heading tag was picked for how it looks (a smaller H3 or H4 happens to match the font size someone wanted) rather than for where that content actually sits in the page's structure.
Why does skipping a heading level matter?
Screen reader users often navigate by heading alone, jumping from heading to heading to scan a page the way a sighted visitor skims with their eyes - a skipped level reads like a section vanished, or leaves them unsure whether they are still inside the section they thought they were in. Google's crawler uses the same outline to figure out which content matters most and how it relates to the rest of the page, so a broken hierarchy is a weaker signal for both audiences at once.
Isn't a heading tag just a bigger font size?
Visually, yes - browsers apply a default bigger, bolder look to H1 through H6, which is exactly why they get misused for their appearance instead of their structural meaning. The fix is to pick the heading level that matches the content's real place in the outline, then use CSS to make it look however you want. Font size is a styling choice; heading level is a structural one, and they should be decided independently.
How do I check my own site's heading structure?
In Chrome, open DevTools (F12), go to the Elements panel, and search for h1 through h6 tags in order down the page - or install a free heading-outline browser extension that lists them for you as a simple nested list. If the list skips a number anywhere (an H1 followed directly by an H3, for example), that is the exact gap the free audit will also flag automatically, naming exactly how many headings it found.
