A Step-by-Step SEO Diagnostic You Can Run on Your Trade Website This Week

The word 'audit' gets used loosely. For a trade website, it means a structured review across four layers — each one affects your ability to appear when a homeowner searches for your service in your area.

• Technical health: Can Google crawl and index your pages? Does the site load fast enough on a phone? Are there broken links, redirect chains, or duplicate content?
• On-page signals: Do your service pages tell Google what you do, where you do it, and why you're the right choice? Are title tags and meta descriptions written for search, not just for aesthetics?
• Local signals: Is your Google Business Profile complete and consistent with your website? Do your citations across directories match? Do you have enough reviews, and are you responding to them?
• Authority signals: Do other credible local websites link to yours — trade associations, local news, suppliers, or chambers of commerce?

You don't need to fix all four areas simultaneously. The audit tells you which layer is causing the most damage to your rankings right now, so you can prioritise intelligently rather than guessing.

One important framing note: an audit is a A Step-by-Step SEO Diagnostic You Can Run on Your Trade Website This Week, not a to-do list. Some issues you find will be quick fixes you handle yourself. Others — particularly technical crawl errors or schema implementation — require a developer or an SEO specialist. Knowing the difference saves time and money.

The sections below walk through each layer with specific checks and free tools. Work through them in order, because technical issues at the foundation will undermine any on-page or local work you do on top.

Technical SEO isn't about code for its own sake. It's about making sure Google can find, read, and understand your pages — and that real visitors don't bounce because the site is slow or broken on their phone.

Page Speed on Mobile

Most trade website visitors arrive on a phone, often mid-job or from a van. Run your homepage and your top service page through Google PageSpeed Insights (free). Look at the mobile score and pay attention to Core Web Vitals — Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS) in particular.

In our experience working with trade businesses, heavy themes built on WordPress page builders are the most common culprit. Oversized images are second. Both are fixable without rebuilding the site.

Crawl Errors and Index Coverage

Open Google Search Console. Navigate to the Coverage or Indexing report. If pages you want ranked are showing as 'Excluded' or 'Not indexed', that's a priority fix. Common reasons include a stray 'noindex' tag left by a developer, or a robots.txt file blocking key pages.

Mobile Usability

Still in Search Console, check the Mobile Usability report. 'Text too small to read' and 'Clickable elements too close together' are common on older trade sites. These don't just hurt user experience — Google's mobile-first indexing means they directly affect how your site is evaluated.

Redirect Chains and Broken Links

Use a free tool like Screaming Frog (up to 500 URLs free) to crawl your site. Filter for 4XX errors (broken links) and redirect chains longer than one hop. Both waste crawl budget and create a poor experience for visitors clicking from directories or old listings.

Once technical issues are documented, move to on-page — but don't start fixing content until the technical foundation is solid.

On-page SEO for a trade website is straightforward in principle: each service you offer, in each area you serve, should have its own page that clearly describes the service, signals the location, and gives a homeowner a reason to call you rather than the next result.

Title Tags and Meta Descriptions

Pull up your site in Screaming Frog and export the title tags and meta descriptions. Look for three problems: missing tags (pages with no title), duplicate tags (the same title on multiple pages), and generic tags ('Home | Joe's Plumbing'). Each service page should have a title along the lines of: [Service] in [Location] | [Business Name]. That's not a rigid formula, but it covers the intent signal Google needs.

Service Page Depth

This is where most trade sites fall short. A service page with one paragraph and a contact form isn't enough. Thin pages — industry benchmarks suggest anything under 400 words for a service page is at risk in competitive local markets — struggle to rank because they give Google and the visitor very little to evaluate.

A stronger service page covers: what the service includes, common problems it solves, what the process looks like, your service area, and social proof (reviews or case examples). It doesn't need to read like a brochure — plain language works better.

Schema Markup

Use Google's Rich Results Test to check whether your pages have structured data. For trade businesses, the most useful schema types are LocalBusiness (or a more specific subtype like Plumber, Electrician, or RoofingContractor), Service, and FAQPage where relevant.

Missing schema doesn't stop you ranking, but it means you're not collecting the enhanced search result features that competitors using schema are already getting.

Internal Linking

Check that your homepage links to all primary service pages, and that service pages link to related services and your contact page. Orphaned pages — those with no internal links pointing to them — get crawled less frequently and rank less reliably.

For most tradesmen, the Map Pack (the three business listings that appear above organic results in local searches) drives more phone calls than the organic results below it. Local signals determine whether you appear there — and whether you appear above competitors when it matters.

Google Business Profile Completeness

Log into your Google Business Profile dashboard and work through every section: business category (your primary category matters most — choose the most specific option available), services listed, service areas defined, business hours including public holidays, photos (exterior, interior, team, completed work), and a complete business description using natural language about what you do and where.

Check that your Name, Address, and Phone number (NAP) on the GBP exactly matches what's on your website's contact page and footer. Any variation — abbreviated street names, different phone formats — creates a consistency signal that can suppress your local rankings.

Citation Consistency

Citations are mentions of your business name, address, and phone number across directories — Yell, Checkatrade, Rated People, TrustATrader, and general directories like Yelp or Thomson Local. Use a free tool like BrightLocal's Citation Tracker or Whitespark to pull your existing citations and check for inconsistencies.

In our experience working with trade businesses, outdated citations from old addresses or old phone numbers are common after a business moves or rebrands. These create conflicting signals that confuse Google about which details are correct.

Review Volume and Recency

Google considers both the number of reviews and how recently they've been posted. A business with 80 reviews, all from two years ago, often ranks below a competitor with 30 reviews posted consistently over the past six months. Note your current review count, average rating, and the date of your most recent review. If reviews have stalled, that's a local signal issue worth addressing.

Authority signals — primarily backlinks from other credible websites — tell Google that your business is trusted by sources beyond your own pages. For tradesmen, this doesn't mean competing with national publications. Local authority signals are what move the needle.

Who's Linking to You?

Use Google Search Console's Links report to see which external sites link to yours. Also run a free check in Ahrefs Webmaster Tools (free for your own verified domain) for a broader picture. You're looking for: trade association memberships with linked directories, supplier or manufacturer pages, local news mentions, and any testimonial or case study links from clients.

What Good Looks Like for a Trade Business

A plumber or electrician with 20-40 relevant, local-context backlinks — from their Gas Safe or NICEIC registration page, local builder's merchant, a local newspaper story, and a handful of trade directories — will typically have stronger authority than a competitor with zero links and one directory. You don't need hundreds of links. You need relevant ones.

Red Flags to Look For

• A large volume of links from irrelevant foreign websites or generic link farms — these can actively harm rankings
• No backlinks at all, even from your own trade association registrations (these should be easy wins)
• Links pointing to old URLs that now 404 — these pass no authority and should be redirected

If your authority signals are thin, the priority is earning natural links: getting listed in every relevant trade body directory, asking suppliers to link to your site, and making sure any press coverage or local sponsorships result in a link back to you. This takes time, but it compounds.

Once you've worked through all four layers, you'll have a clear picture of which issues are suppressing your rankings most. If the scope feels large — particularly if technical issues, thin content, and citation problems all showed up — that's a natural point to consider booking a professional SEO audit for your trade business rather than attempting to fix everything manually.
