Questions people ask
How do you check a page's heading structure?
Open your page, view its source, copy the HTML and paste it into the box. The tool shows the H1 to H6 outline and flags missing, repeated or skipped headings. One clear H1 and headings in order make pages easier for readers, screen readers and search engines. Nothing is fetched or uploaded.
- H1-H6 Full outline. In page order.
- Flags Missing, repeated, skipped.
- Paste HTML No fetching. Works before launch.

What is heading structure?
It's the outline formed by a page's headings, from H1 for the main title down to H2, H3 and further for sections and sub-sections. A logical structure helps readers skim, lets screen reader users jump between sections, and helps search engines understand what each part covers.
Is one H1 per page a rule?
HTML allows more than one, and search engines cope, but one clear H1 that names the page is the simplest and most accessible structure. It should match what the page is about, much like the title tag, so visitors know at once they're in the right place.
Why do skipped heading levels matter?
Screen reader users move through a page by headings, and a jump from H2 straight to H4 suggests missing content. Keep levels in order: H2 for sections, H3 inside them. It also keeps your page's outline easier for search engines to follow. Fixes are usually quick.
Does it fetch my live page?
No. You paste the HTML yourself, which keeps this tool private and means it works for pages that aren't public yet, such as a draft or a staging site. To analyse a live public page instead, use the Meta tag analyzer. Paste only what you need.
Does it read headings built by JavaScript?
Only if they're in the HTML you paste. View source shows the original HTML; copy from the browser's Elements panel instead to include headings that scripts add after the page loads. Many website builders add headings this way. Compare both if unsure. Compare both versions.
How do I get my page's HTML?
Open the page in a browser, right-click and choose View page source, then select all and copy. On most computers, Ctrl+U opens the source. Paste it into the box here and the outline appears straight away. The outline shows every heading in order. Copy everything at once.
What makes a good heading outline?
An H1 with the page's main topic, H2s for each major section, and H3s for sub-points within them. Headings should describe their section clearly, such as 'How to book' rather than 'Section 2', so someone skimming understands the page. Read it like a contents list.
Do headings help SEO?
Yes, indirectly. Clear headings help search engines understand the topics a page covers, and they help readers find answers, which keeps them on the page. Question-style headings with direct answers below them also suit AI search and featured snippets. Clarity helps everyone. Write them for readers first.
Is the HTML I paste sent anywhere?
No. It's analysed in your browser and stays on your device. That makes it safe to check pages containing unpublished content or client work. Nothing is stored, and there's no account. That keeps drafts private until you're ready to publish them. No account is needed.
Why does my page have no H1?
Some themes and builders style the page title without using an H1, or use an H1 only for the logo. Check your theme settings or ask your developer to make the page's main title an H1, and remove any H1 wrapped around the logo. Recheck after fixing.
Should headings include keywords?
Where it's natural, yes, because headings describe topics. Don't force keywords into every heading; write headings that tell readers what each section answers. Varied, descriptive headings usually cover related searches better. Write each heading as the question or topic that its section actually answers. Keep them natural.
Are headings used for styling a problem?
Yes. Using heading tags just to make text big or bold, such as an H3 for a phone number, confuses the outline. Use headings only for section titles, and style other text with CSS so the structure stays meaningful. Fix them in the theme. Themes often cause it.
Does it check Hindi pages?
Yes. The checker reads heading tags regardless of language, so Hindi, Marathi and other pages show their outline the same way. The checks are about structure, not wording. Mixed-language pages work too, since only the heading tags and their order are checked. Mixed languages work too.
Does it work on a phone?
It works in mobile browsers, but copying a page's full HTML is awkward on a phone. A computer is much easier for viewing source, copying and reading the outline. Nothing is uploaded, and you don't need an app or an account to use it on your phone.
Is it free?
Yes. The heading structure checker is free, with no sign-up and no limit. It's one of the free SEO tools from Marketiism, alongside a meta tag analyzer and readability checker. Nothing is added to the code or text it produces, and you can use it for client and business work as often as you like.
