Technical SEO for service business websites: the fixes that matter

Why technical SEO matters for local businesses

Contractor websites are usually built quickly, often on a template, by someone who is not thinking about search. That is fine until Google cannot find half your service pages, the site takes eight seconds to load on a phone, or every town page is a near-copy of the last. None of these problems are visible to you, but all of them hold rankings back.

Technical SEO is the foundation under everything else. Great content and strong reviews help far less if Google cannot crawl and index the pages that hold them. It matters for AI search too. Google's own documentation on AI features is clear that there is no secret technical trick:

“There are no additional technical requirements.”

In other words, the same technical basics that get you indexed in Google Search are what make you eligible for Google's AI features.

The free tools you need

Indexing: can Google see your pages?

Open the Pages report in Search Console. It lists every URL Google knows about and whether it is indexed. For a small contractor site, every important page should be in the index. Common reasons pages are left out:

• Noindex tags left on from when the site was built. Many website builders have a "discourage search engines" setting that stays on after launch.
• Blocked in robots.txt, often by accident when a whole folder is disallowed.
• Duplicate or near-duplicate content. Google picks one version and ignores the rest. This happens a lot with copy-paste town pages.
• Thin pages with a heading and two sentences, which Google crawls but chooses not to index.
• Orphan pages that no other page links to, so Google rarely finds them.

Submit an XML sitemap in Search Console so Google has a complete list of your pages, and make sure it only lists pages you want indexed. If you are unsure what a good sitemap looks like, Google's sitemap overview↗ explains the format.

Speed and Core Web Vitals

Core Web Vitals are Google's measures of how fast and stable a page feels to real users. You can see your site's scores in Search Console and PageSpeed Insights. These are the thresholds for a "good" score, as published on web.dev↗:

The fixes that make the biggest difference on most service sites:

1. Compress and resize images. A phone does not need a 5,000-pixel job photo.
2. Use modern formats like WebP and set width and height on every image.
3. Remove plugins, sliders and widgets you do not use.
4. Load chat widgets and review carousels after the main content.
5. Use decent hosting with caching, or a platform that handles it for you.

Mobile experience

Most local searches happen on phones, often while something is going wrong at home. Google indexes the mobile version of your site first, so the mobile version is the one that counts. Check each core page on your own phone:

• Is the phone number a tap-to-call link, visible without scrolling?
• Is the text readable without zooming, and are buttons big enough to tap?
• Do pop-ups cover the content? Intrusive ones frustrate users and can hurt rankings.
• Does any content scroll sideways off the screen?

Site structure and internal links

A clear structure helps Google understand what your site is about and which pages matter most. For a home service business, a simple structure works best:

• Homepage linking to each core service page
• Each service page linking to related services and the main towns you serve
• Area pages linking back to the relevant services
• Blog articles linking to the service they relate to

Every important page should be reachable within two or three clicks of the homepage, and none should be orphaned. Use descriptive link text, such as "water heater replacement", rather than "click here". Fix broken links and avoid chains of redirects, especially after a redesign.

Titles, headings and duplicates

These sit on the line between technical and on-page SEO, but they are among the most common problems a crawl finds:

• Duplicate titles, such as every page titled "Home | ABC Plumbing". Each page needs a unique title naming its service and town, ideally under about 60 characters so it is not cut off.
• Missing or duplicate meta descriptions. They do not directly rank you, but a clear description improves clicks.
• No H1, or several. Each page should have one main heading that says what it is about.
• Mixed URL versions, such as http and https, or with and without www, all live at once. Pick one and redirect the rest.

Structured data

Structured data, often called schema markup, labels information on your pages in a format search engines read easily. For a home service business, the most useful types are:

• LocalBusiness (or a more specific type such as Plumber or RoofingContractor) with your name, address, phone, hours and service area
• Service on each service page
• FAQPage where a page genuinely has questions and answers
• BreadcrumbList to describe where a page sits in your site

Test it with the Rich Results Test, and keep it honest: marking up reviews you do not show, or details that are not on the page, breaks Google's guidelines. See Google's LocalBusiness documentation↗ for the details, or the local business schema guide for a copy-ready example.

AI crawlers

Search engines are no longer the only bots that matter. If you want AI tools to recommend your business, they need to be able to read your site. Security plugins, firewalls and copy-pasted robots.txt rules sometimes block them without the owner knowing.

Check your robots.txt file (yoursite.com/robots.txt) and any bot-blocking settings. For example, OpenAI documents↗ separate crawlers for ChatGPT search and for model training, so you can allow one and block the other. The full picture is in how to get recommended by ChatGPT and AI search.

Common problems by website builder

Most contractor websites run on one of a handful of platforms. Each has its own typical problems, so knowing yours tells you where to look first.

Whatever the platform, the fixes are the same in principle: fewer and lighter page elements, unique titles and content, every important page indexed, and nothing blocking the crawlers you want.

Redesigning your site without losing rankings

A new website is one of the riskiest moments for a local business's rankings. I regularly see contractors lose half their search traffic after a redesign, almost always for the same avoidable reasons. Before launch:

1. Export a list of every current URL, and note which ones get traffic in Search Console.
2. Map each old URL to its closest new page, and set up permanent (301) redirects.
3. Keep the content that ranks. Rewriting a page that ranks well is a gamble.
4. Copy over titles, meta descriptions and structured data, or improve them.
5. Make sure the new site is not set to noindex when it goes live.
6. Submit the new sitemap and watch the Pages report closely for the following weeks.

If rankings drop after launch, check redirects first. Missing redirects are the cause far more often than anything else.

Technical SEO audit checklist

Most contractor sites fail three or four of these on the first audit, and fixing them is often the fastest win in a local SEO campaign because it unlocks pages Google was ignoring.

If you would rather someone check all of this for you, my Technical SEO service covers it, and an SEO audit gives you a prioritized fix list. Technical work is also included in every monthly plan, alongside the rest of the local SEO checklist.
