Alright, this one's a little nerdy. But stick with me because it matters way more than you'd think.

Your website has headings. The big text. The titles of sections. The stuff that's bigger and bolder than the regular text.

Behind the scenes, those headings have code labels. H1, H2, H3. It's a hierarchy. Like a table of contents for your page.

And if they're set up wrong (which, on most plumbing websites, they absolutely are), Google has no idea what your page is about.

Which means you're not ranking. And you don't know why.

What Are H1, H2, and H3 Tags?

Think of it like a book.

1. H1 = The book title. There's only one per page. It tells Google (and your visitors) exactly what this page is about.
2. H2 = Chapter titles. The main sections of your page. There can be several.
3. H3 = Sub-sections. Details within each chapter.

Here's an example for a drain cleaning service page:

1. H1: Drain Cleaning Services in Austin, TX
2. H2: Kitchen Drain Cleaning
3. H3: Signs Your Kitchen Drain Is Clogged
4. H2: Bathroom Drain Cleaning
5. H3: Common Causes of Bathroom Drain Clogs
6. H2: Why Choose Us for Drain Cleaning
7. H2: Contact Us Today

See how it flows? Each heading gets more specific. Google reads this and thinks: "Okay, this page is about drain cleaning in Austin. It covers kitchen drains, bathroom drains, and has a section about why to choose this company."

That's a page Google can rank. Because it understands exactly what it's about.

What Most Plumbing Websites Get Wrong

Now here's what actually happens on most plumbing sites.

Problem 1: Multiple H1 tags. Some website builders (looking at you, Wix) slap an H1 tag on every big piece of text. So your page has 5 H1 tags. Google reads that and gets confused. It's like a book with 5 titles. Which one is it actually about?

Problem 2: No H1 tag at all. Some sites skip the H1 entirely. The page title is just styled to look big, but it's not coded as an H1. Google sees a page with no title. Not helpful.

Problem 3: H1 tag says something useless. I've seen plumbing websites where the H1 is "Welcome" or "Home" or just the company name. That tells Google nothing about what services you offer or where you're located.

Problem 4: Random heading order. H3 before H2. H1 buried in the middle of the page. Headings used just because they "look big," not because they serve a structural purpose.

It's a mess. And it's hurting your rankings every single day.

How to Fix Your Headings (The Simple Way)

Here's the rule. Follow it and you'll be ahead of 80% of plumbing websites.

Every page gets exactly ONE H1 tag. This is the main headline of the page. It should include your primary keyword and (if it's a service page) your city.

Examples: - Homepage H1: "Licensed Plumber in Denver, CO. Available 24/7." - Service page H1: "Water Heater Repair and Installation in Denver" - Blog post H1: "How to Know When Your Water Heater Needs Replacing"

Use H2 tags for major sections. Each main section of the page gets an H2. Think of these as the big topics you're covering on the page.

Use H3 tags for sub-sections within H2 sections. These are the details. If your H2 is "Types of Water Heaters We Install," your H3s might be "Tankless Water Heaters," "Traditional Tank Water Heaters," and "Heat Pump Water Heaters."

Never skip levels. Don't go from H1 directly to H3. Always go H1 > H2 > H3, in order.

Why This Matters for SEO

Google's crawlers read your heading structure to understand your page.

Good heading structure tells Google: - What the page is about (H1) - What topics the page covers (H2s) - What specific details are included (H3s)

This helps Google match your page to the right search queries. When someone searches "drain cleaning in Austin," Google looks for pages with heading structures that clearly indicate the page is about drain cleaning in Austin.

A page with a clean heading hierarchy ranks better than a page with messy or missing headings. Period.

It also helps your visitors. People scan, they don't read. Headings tell them where to find the information they're looking for. This is a key part of on-page SEO. A well-structured page keeps people on your site longer. And longer time on site = better rankings.

How to Check Your Headings Right Now

Here's a quick way to see what your headings actually look like.

1. Open your website in Chrome
2. Right-click on any heading and select "Inspect"
3. Look at the code. You'll see `

   `, `

   `, `

   `, etc.

Or use a free tool like the "SEO Meta in 1 Click" Chrome extension. You can also check heading issues in Google Search Console. It'll show you all the headings on any page in seconds.

What you want to see: - One H1 per page - H2s under the H1 - H3s under the H2s (if any) - Keywords included naturally in headings

What you don't want to see: - Multiple H1 tags - No H1 at all - Headings out of order - Headings that are just "Learn More" or "Welcome" or "Info"

Common Heading Mistakes by Page

Homepage: - Bad H1: "Welcome to Our Website" - Good H1: "Trusted Plumber in [City], [State]. Same-Day Service."

Service page: - Bad H1: "Our Services" - Good H1: "Drain Cleaning Services in [City]"

About page: - Bad H1: "About" - Good H1: "Family-Owned Plumbing in [City] Since 2005"

Blog post: - Bad H1: "Blog Post" - Good H1: "5 Signs You Need to Replace Your Water Heater"

See the pattern? Every H1 should tell Google (and the visitor) exactly what this page is about, including your location when relevant.
