Quick answer: Use one H1 that names the page’s topic, H2s for the main sections and H3s only for parts of an H2. Write each heading so it tells the reader what the section gives, use your keyword naturally once in the H1, and never use headings just for styling. The 7 mistakes and the full checklist are below.
A few months ago I opened a client’s homepage source and found nine H1 tags. The logo was an H1, so was the footer slogan, and a “Subscribe” button was an H3. The team told me they had “done the SEO”. They had installed a plugin and never opened the page structure.
Headings are the easiest part of on-page SEO to fix and also the most over-hyped. So before the mistakes, one honest reset.
What Google actually says about headings
Google’s SEO Starter Guide is modest on this topic. It recommends providing headings to help users navigate pages. It says semantic order is great for screen readers, but that Google Search does not mind if you use headings out of order, and that there is no magic number of headings; if you think it is too much, it probably is. It also notes that Google can build a page’s title link from the title element and other headings on the page.
So headings are not a secret ranking lever. They are signposts. Good signposts help people stay, help screen-reader users move around, and help search engines see how your page is organised. The mistakes below all damage that clarity.
Mistake 1: No H1 at all
Page builders and custom themes often skip it. Without a main heading, the page has no clear title for the person who just arrived.
Fix: add one visible H1 that states what the page is about, in natural words, for example “H1, H2, H3 Tags SEO: 7 Mistakes to Fix”. If your main topic fits, include it once. Do not force it.
Mistake 2: Many unrelated H1 tags
My nine-H1 client is the extreme case. Themes often wrap the logo, sidebar titles or banners in H1. HTML5 technically allows more than one H1 and Google can cope, but a page with five competing “main titles” confuses humans and tools.
Fix: use one H1 for the page’s main title. Turn the logo into a plain link or image and demote widget titles to lower levels or plain text. Fix this in the theme template, not page by page.
Mistake 3: Using headings for looks
Someone likes how an H3 looks, so every bold line becomes an H3, including “Call us today”. The outline then reads like nonsense.
Fix: headings are for structure; use CSS for size and colour. If a line is not the title of a section, it should not be a heading.
Mistake 4: Stuffing keywords into every heading
“SEO Services Noida”, “Best SEO Services in Noida”, “Affordable SEO Services Noida Company”. Readers see it instantly and trust drops.
Fix: use your main keyword naturally in the H1 if it fits. In H2s and H3s, describe the section in plain words and use related terms. Ask: would a human write this heading?
Mistake 5: Vague headings
“Introduction”, “More information”, “Overview”, “Benefits”. A reader scanning the page, or a screen-reader user jumping heading to heading, learns nothing.
Fix: say what the section gives. “What are header tags?” beats “Introduction”. “How to write a good H1” beats “Tips”. Where people actually ask a question, phrase the heading as the question and answer it right below.
Mistake 6: A messy hierarchy
H1, then H4, then H2, then H3, then another H1. Google says order does not matter for search, but a logical hierarchy is genuinely better for screen readers and for anyone maintaining the page later.
Fix: H2 for main sections, H3 for parts of an H2, and deeper levels only if the content really nests. Most blog posts never need H4 to H6.

H2: Mistake 1: No H1 at all
H2: Mistake 2: Many unrelated H1 tags
H2: How to structure H2 and H3 tags
H3: One idea per section
H3: Use questions where people ask them
H2: Checklist
Mistake 7: Too many, too long
A heading before every two sentences, or a heading that runs to two lines. Google says there is no ideal number, and that too many is probably too many.
Fix: use as many headings as the content needs, no more. If a heading needs two lines, it is probably a sentence and belongs in the paragraph.
Why this matters beyond Google
Headings do three jobs at once. They help a visitor scan and decide in seconds whether the page answers their question. They give screen-reader users a map, because many jump from heading to heading to find what they need. And they make your content easier for any system, search engine or AI tool, to understand and quote accurately. I would not promise citations or rankings from headings alone, but a clean outline removes friction for all three audiences, which is why I fix it first on almost every audit.
H1 versus title tag: not the same thing
The title tag appears in search results and your browser tab; the H1 appears on the page. They should describe the same page but need not match word for word. Write the title tag to earn the click, and the H1 to confirm to the visitor that they landed in the right place.
The quick checklist
• ☐ One clear H1 that matches the page’s purpose
• ☐ H1 and title tag describe the same page
• ☐ H2s for main sections, H3s only where needed
• ☐ Every heading describes its section honestly
• ☐ Main keyword used naturally; no stuffing
• ☐ No headings used just for styling
• ☐ No logo, menu or banner wrapped in an H1
• ☐ Read the headings alone: do they tell the story?
How to check your own page in two minutes
Right-click the page, choose Inspect, and search the HTML for <h1. Or use a crawler or browser extension that lists headings. Look for a missing H1, several H1s, empty headings and odd levels. Then fix the template that creates them. Running an online store? Category and product templates are the usual culprits, so add this to your e-commerce SEO audit.
The bottom line
Headings will not rescue weak content, but they make strong content easier to scan, easier to navigate and easier to understand. Fix the seven mistakes above, run the checklist, and move on to the work that matters more: the content itself.
