If you’ve ever wondered why some local trades rank on page one of Google while others vanish into digital obscurity, the answer often comes down to one thing: topical authority.
Topical authority is Google’s way of recognising who really knows their stuff in the trade industry. It’s the difference between a cowboy builder and a time served professional who’s earned their reputation through years of experience, customer satisfaction and consistent quality. Google is the customer and topical authority is your proof of expertise.
In plain English, it means showing Google that you’re the go-to source for your trade. Whether you’re a plumber explaining central heating systems, a decorator discussing paint finishes, or a roofer sharing advice on slate repair, every well-written, interconnected piece of content strengthens your topical authority.
According to Semrush’s 2025 SEO Trends Report, search engines increasingly favour websites that cover topics comprehensively rather than briefly. In fact, sites demonstrating clear topical depth see up to 80% higher organic visibility within six months.
Aimee Lycett, SEO strategist at Local Trade Websites, says: “Google’s getting smarter about identifying the real experts. You can’t just say you’re a roofer anymore, you have to prove it through the content you create, the consistency of your message and how often you help people answer real world questions.”
So, let’s unpack what topical authority really means for tradespeople and how you can build it without writing like a robot or spending your evenings battling AI tools and jargon.
In simple simples terms, topical authority is Google’s trust in your expertise. It’s the digital version of your reputation, something every tradesperson understands. When homeowners recommend you because “you really know your stuff,” that’s real-world authority. Topical authority is exactly the same, it's just online.
It’s built when your website covers multiple aspects of your trade in depth. For example let’s say you’re an electrician. Instead of just having a single “Electrical Services” page, you might create supporting content like:
Each piece of content reinforces your expertise, showing both Google and customers that you’re not just an electrician, you’re the expert in your area.
A Search Engine Journal study found that websites ranking for multiple subtopics within one niche see 65% higher keyword coverage across their content, which translates into more clicks, calls, and leads.
Rob Gould, director at Local Trade Websites, puts it plainly: “Topical authority is your online reputation. The more you talk about your trade, in detail, accurately and consistently. The more of this you do the more Google sees you as the go-to expert. It’s like word-of-mouth but for bots and algorithms.”
Before you can dominate Google with blogs and guides, your core service pages need to be rock-solid. Think of them as the structural base for your topical authority.
For a builder, that means having clear detailed service pages on extensions, loft conversions and renovations. For a plumber, you’ll need pages for boiler installation, bathroom fitting and leak detection. For a landscaper, that could mean garden design, fencing and patios.
Each service page should clearly explain:
Once those foundation pages are in place, build supporting content around them, what’s known as “topic clustering.” If your main service page is Roof Repairs, your cluster might include:
Each article links back to your main page, creating a web of relevance that Google loves.
A Content Marketing Institute report found that sites interlinking blogs and service pages can increase average session duration by over 40%, signalling to Google that users find your content valuable.
Aimee Lycett explains: “When we optimise trade websites, we treat each service as a hub. Every blog becomes a spoke leading back to it. That interconnected structure is what builds authority faster than any paid ad campaign ever could.”
This is where most trades fall short. Too many sites use generic, filler text that could apply to anyone. But Google now measures expertise, experience, authority, and trust (E-E-A-T) and that’s where real-world trades can shine.
You don’t need to write like Shakespeare; you just need to write like someone who’s been on-site for 10 years and knows the job inside out. Take this example: instead of “We repair windows to a high standard,” say “We use Accoya timber and traditional putty glazing to ensure period windows stay draught-free for decades.” Those details prove knowledge.
If you’re a roofer, explain the pros and cons of clay versus slate. If you’re a decorator, talk about how humidity affects certain paints. The more specific your content, the more Google associates your site with real expertise.
Use free tools like AnswerThePublic or AlsoAsked to find what people are genuinely asking. These tools show you what potential customers are typing into Google, so you can create blogs that answer those exact questions.
According to LocaliQ, businesses that publish niche, educational content get 68% more organic traffic and 54% more conversions than those relying on generic pages.
Rob Gould adds: “You already have the knowledge; it’s just hidden in your day-to-day work. Write the way you’d explain it to a customer face-to-face. Google can tell when content comes from genuine experience and so can homeowners.”
Now that you’ve got a content plan, it’s time to organise it. Imagine your website as a house: the foundation is your main service pages, the walls are your supporting blog and the wiring is your internal links.
Linking related pages together tells Google that you cover a topic comprehensively. For example, a plumber might link:
Each internal link keeps visitors on your site longer and helps Google understand your hierarchy of expertise.
A HubSpot report on SEO architecture found that topic clusters can improve organic traffic by up to 90% after six months due to better crawlability and user engagement.
Aimee Lycett notes: “When your site reads like a well-organised guidebook instead of a random collection of pages, Google rewards you. Internal linking isn’t just SEO. it’s how you guide customers through your expertise step-by-step.”
To make it work ensure every page links to at least one other, use natural anchor text (not just ‘click here’), and update older blogs with new links as your site grows.
Topical authority however doesn’t live in isolation, Google also looks for what others say about you. Backlinks, citations, reviews and mentions are your online recommendations.
Start with local citations, directories like Yell, Rated People, Checkatrade, and Houzz. Make sure your business name, address, and phone number are identical across all listings.
Next, seek natural backlinks from:
According to Moz’s Local Ranking Study 2025, backlinks remain the third most important ranking factor for local businesses, just behind relevance and reviews.
Rob Gould explains: “We tell every client to think of backlinks like professional references. A link from a respected local website or supplier is like a recommendation from someone credible. It’s one of the fastest ways to earn Google’s trust.”
If you’re ambitious, you can also produce data-based content, things like “The 5 Most Common Roofing Problems in Kent.” Local journalists love these because they’re useful and quotable, giving you free PR and a quality backlink in one go.
