How to Optimise header tags (H1, H2, H3, etc.) with target keywords.
Most small business websites I look at have a header tag problem. Not a design problem, a structure problem. The H1 is missing, or there are three of them. The H2s repeat the same phrase four times. Nobody has thought about where the target keyword actually sits.
It sounds like a small technical detail. It isn't. Header tags are one of the clearest signals you give Google about what a page is actually about, and getting them wrong is one of the quietest ways a good business loses rankings it should be winning.
I have been doing SEO for Derbyshire and East Midlands small businesses for 18 years, and header tags are still one of the first things I check on any new client's site. In this post I will show you exactly how to optimise your H1, H2 and H3 tags with target keywords, without turning your content into keyword soup.

Header tags (H1, H2, H3 and so on) are the labels you put on the sections of a page. Google's crawlers read them to understand your content's structure before they read a single sentence of body text.
Think of your header tags as a contents page. A visitor scanning your website in three seconds should be able to tell what the page covers just from the headings. If Google can do that too, you are already ahead of most of your local competitors.
What search engines actually do with H1, H2 and H3 tags
Search engines use your header hierarchy to work out the main topic of the page (the H1), the supporting sub-topics (the H2s), and the finer detail underneath each of those (the H3s). Get the target keyword into the right level of that hierarchy and you are telling Google, in the clearest possible way, what you want to rank for.
This matters just as much for AI-powered search and answer engines as it does for classic Google rankings. They lean on the same structural signals to decide which page to quote or cite.
The cost of getting header tags wrong
I worked with a joinery business near Ashbourne whose service pages all used the same generic H1: "Our Services". Every page. Google had no way of knowing which page was about kitchen fitting and which was about bespoke staircases, so it ranked none of them well.
We rewrote every H1 to include the specific service and the town it served, restructured the H2s around the questions customers actually search for, and their organic enquiries from search nearly doubled within four months. No new content budget. No paid ads. Just header tags doing their job properly.
Your H1 is not a slogan. It is the single clearest ranking signal on the page, and most small business sites waste it. Stuart Baddiley, Optimise Your Marketing
How to optimise your H1 tag with target keywords
Your H1 is the most important header tag on the page, and it should follow three simple rules.
One H1 per page, no exceptions
Every page needs exactly one H1. Not zero, not three. If your Squarespace or WordPress theme is auto-generating a second H1 somewhere in your template, that is worth fixing before you touch anything else.
Put the primary keyword near the front
Your primary target keyword should appear in the H1, ideally in the first few words. If you run a bakery in Wirksworth and you want to rank for "wedding cakes Derbyshire", your H1 should say something close to that, not "Welcome to Our Bakery".
Make it specific to that page
Every H1 across your site should be unique. If you are copying the same H1 template across ten service pages and only swapping one word, Google will struggle to tell those pages apart, and so will your customers.
How one Derbyshire retailer fixed its rankings without new content
A homeware retailer in Matlock came to us ranking on page three for their main keywords. We restructured their header tags across 40 product category pages, alongside a wider technical SEO clean-up, and they moved to page one for 12 of their top 15 target terms within three months.

Once your H1 is solid, your H2s should break the page into logical sections, each covering one clear sub-topic. Use secondary keywords or natural variations of your primary keyword here, not the exact same phrase repeated word for word.
Avoid keyword stuffing
If every single header on the page contains your target keyword in exactly the same order, that is a red flag to Google, not a ranking boost. Vary the phrasing. Use related terms your customers would actually type in, including local phrases if you serve a specific area like Derbyshire or the wider East Midlands.
Use H3s for the detail, not the headline
H3 tags are for breaking down a section further, capturing long-tail phrases and the kind of longer, more conversational questions people now type into voice search and AI tools. "How much does a kitchen fitter cost in Derby" is a perfectly good H3.
Keep the hierarchy logical
H1, then H2, then H3, in that order, with nothing skipped. A page that jumps from H1 straight to H3 confuses both search engines and screen readers, which matters for accessibility as well as SEO.
Header tag structure is one piece of a much bigger picture. It works alongside your wider local marketing effort and needs checking regularly through proper testing and measurement, not set once and forgotten.
Where header tags fit in your BIG12 marketing plan
Header tags sit inside the SEO pillar of our BIG12 framework, the 12 marketing pillars every small business needs to get right to grow properly. On their own, well-optimised headers will not fix a business with no content plan or a broken CRM. But get all 12 pillars working together and the compounding effect is significant.
I built BIG12 over 18 years of working with Derbyshire and East Midlands businesses because I kept seeing the same pattern: one part of the marketing being excellent and the other eleven being ignored. You can read the full framework on our BIG12 training page.

Everything in this post is straightforward. One H1 per page, keywords near the front, a logical hierarchy underneath. None of it is difficult to understand.
The gap is always the same one I see with every Derbyshire and East Midlands business I work with. Knowing what to do and actually going through 40 pages of a website, tag by tag, fixing it properly, are two very different things. Most owners have a business to run and no spare afternoon for that.
That is where we come in. We do the auditing, the fixing and the ongoing testing, so your header tags, and the rest of your SEO, keep working for you instead of sitting on a to-do list.
