Most contractors think about SEO in terms of the stuff that’s visible: keywords on a page, a Google Business Profile, maybe some backlinks if their agency has been nudging them about it. What rarely comes up in those conversations is internal linking strategy, which is a shame, because it’s one of the highest-leverage things you can fix on a website you already own. No outreach. No waiting on third parties. Just your own pages, talking to each other better than they currently do.
The average contractor website has somewhere between fifteen and sixty pages when you count service pages, location pages, blog posts, the about page, the careers section nobody updates. Those pages are not created equal, and Google knows it. What Google is trying to figure out, every time it crawls your site, is which pages are the most important ones. Internal links are a big part of how you tell it.
Here’s where most contractor sites fall down. The homepage links to the navigation. The navigation links to the main service pages. And then everything else, the blog posts, the deep service subcategories, the city-specific landing pages, floats out there with almost nothing pointing at them. Google crawls them eventually, but with very little signal that they matter. So they rank poorly, or they don’t rank at all, and the contractor looks at their analytics and wonders why nobody visits those pages.
What Internal Links Actually Do (Beyond the Obvious)
You probably already know that internal links help visitors navigate your site. That’s true, but it’s almost beside the point when you’re thinking about SEO. The more important function is something called PageRank flow, which is the way authority and relevance move through your site based on which pages link to which other pages.
Google’s own documentation has described internal links as one of the primary ways it discovers new content and determines a page’s importance. When a high-authority page on your site, say your homepage or a page that has earned a lot of backlinks, points to another page, some of that authority passes through. That receiving page becomes, in Google’s model, more credible and more worthy of ranking. When your service pages have nothing pointing at them except the navigation bar, they’re working with almost nothing in reserve.
Think about what that means practically. You write a detailed page about commercial roof replacement in your metro area. It’s well-written, it has good keywords, you’ve put real effort into it. But your homepage doesn’t link to it, your blog doesn’t link to it, your main roofing services page doesn’t link to it. The only way anyone finds it is through the navigation dropdown. Google sees a page that nobody on your own site thinks is worth mentioning. Why would it rank that page well?
If you want to go deeper on the foundational concepts here, our explainer on what SEO actually is and how it works is a good starting point before you get into the mechanics of linking.
The Pages That Deserve More Links Than They’re Getting
Not every page on your site should be linked to constantly. Some pages, like your privacy policy or your thank-you page after a form submission, don’t need to be in the linking rotation at all. But most contractor websites are systematically underlinking to exactly the pages that should be getting traction in search.
Service pages are the obvious ones. If you do HVAC installation, plumbing repair, electrical panel upgrades, and general contracting, each of those service categories should be getting links from multiple places across your site, not just from the main navigation. Your blog posts should be linking to relevant service pages whenever there’s a natural connection. Your about page can link to services. Your FAQ page should be a linking machine, sending people to the specific service that answers whatever question they’re asking.
Location pages get neglected even more. A lot of contractors spend real money building out city-specific landing pages, and then link to them only from a “service areas” dropdown that Google crawls once and basically ignores. If you want those location pages to rank, they need links from your blog posts about work done in that area, from your main service pages that mention the city, from your homepage if the city is important enough to your business. A location page with two inbound internal links is not a page Google will take seriously, no matter how well-written it is.
There’s also the blog, which most contractors treat as a separate island. Posts go up, they live on the blog index page, and they never get woven into the rest of the site. That’s backwards. Blog content that does real SEO work is blog content that links outward to your service pages and receives links from other posts and pages. Keyword research for contractors is something we’ve written about separately, and the principle there applies here too: the content you create needs to function as part of a connected system, not as isolated pieces.
An Internal Linking Strategy That Actually Holds Together
Start with a simple audit. Open a spreadsheet and list every page on your site. For each page, note roughly how many internal links point to it. You don’t need a fancy tool for this, though tools like Screaming Frog or Ahrefs Site Audit will make it faster. What you’re looking for is the obvious orphans: pages with one or two inbound internal links that you actually want people to find and that you want to rank.
Then look at your highest-authority pages. Your homepage almost always has the most authority, because it tends to attract the most backlinks from external sites and sits at the top of your navigation hierarchy. What is your homepage linking to? Most homepages for contractor websites link to a handful of main service categories, a few callouts, and that’s it. If there are specific pages you care most about ranking, think about whether there’s a natural, honest way to link from your homepage to those pages.
The word “honest” matters here. Google is not fooled by stuffing thirty links at the bottom of a page in a way that no human would ever click. The links you add should be the kind that genuinely help a visitor who’s on that page. If someone is reading your homepage and you want them to know about your commercial services in a specific city, a link there makes sense. If you’re cramming in a link just to pass authority, it reads as spam, and Google’s been good at detecting that for years.
Your blog is where most of the organic linking opportunity lives. Every time you publish a post, ask yourself: which service pages does this topic connect to? Which other posts have I written that are related? Link to them, from within the body copy, with anchor text that describes what the reader is about to find. “Homeowners often ask us how long this kind of project takes before they commit” with a link to your project timeline FAQ is a good internal link. “Click here” is not.
Anchor Text Is Not Just a Detail
A lot of people treat anchor text as an afterthought, but it’s one of the clearer signals you can send Google about what a destination page covers. When you link to your roof repair service page, “our roof repair services” as anchor text is fine. “This page” tells Google nothing. “Click here” tells Google nothing. You want the anchor text to describe the content the link leads to, because Google reads it as a relevance signal for that destination page.
You also don’t want to be robotic about it. If you have twelve blog posts that all link to the same service page, you don’t need all twelve to use identical anchor text. Vary it naturally. “Our emergency plumbing team”, “licensed plumbers in [city]”, “what to do when a pipe bursts” pointing to the same page is fine. It actually looks more natural and gives Google slightly more context about what that page is relevant for.
One thing worth understanding is how internal linking connects to your overall domain health. Domain authority is a related concept that shapes how much your links, both internal and external, actually move the needle. A site with stronger overall authority passes more value through each internal link it creates.
The Silo Structure a Lot of SEO People Swear By
Some SEO practitioners love what’s called a silo structure, where you group related pages into topical clusters and link heavily within each cluster but less across clusters. The idea is to signal topical depth to Google: here is a site that covers roofing thoroughly, with a main roofing page, a commercial roofing subpage, a residential roofing subpage, a roof repair subpage, and a half-dozen blog posts all linking to and from each other.
It works. But most contractor websites are not organized this way, and rebuilding from scratch isn’t always realistic. The practical version is simpler: make sure pages about similar topics link to each other. If you have five blog posts about water heaters, they should probably reference each other. Your water heater installation service page should link to those posts, and they should link back to it. You don’t need a perfectly structured taxonomy. You just need the topically related pages on your site to be aware of each other.
For a deeper look at how on-page signals fit together with linking, the on-page SEO checklist for contractor websites covers a lot of the elements that work alongside your linking structure.
How Often You Should Revisit This
Internal linking is not a one-time fix. Every new page you add to your site creates new linking opportunities, and if you’re not building them in intentionally, you’re slowly accumulating more orphan pages over time. The fix is a small habit: when you publish something new, spend five minutes asking where on your existing site it should be linked from, and where within it you can link out to existing pages.
For most contractor sites publishing a blog post every one to four weeks, that’s a minor time commitment with a compounding return. Moz research has put the percentage of pages on the average website that receive zero internal links at somewhere around 30%, which means roughly a third of the content most sites have created is functionally invisible to both Google and real visitors. That number is almost certainly higher on contractor sites, where blog content gets published without a linking plan and service subcategories get added without anyone updating the pages that should be pointing to them.
SEO in general is a slow game. If you’re newer to it, our post on how long SEO takes to work is worth reading before you get frustrated with the timeline. Internal linking improvements tend to show results faster than most other SEO work, but “faster” in SEO still usually means months, not days.
A Note on Link Building Versus Internal Linking
These are related but different problems. Backlinks, links coming from external sites to yours, are a separate conversation entirely. We’ve written about what local businesses get wrong about link building, and the short version is that most contractors overestimate how many backlinks they need and underestimate how poorly their existing site structure is serving the authority they already have. Fixing your internal linking first makes any backlinks you earn later more effective, because the authority those links bring in has somewhere useful to flow.
Internal linking is also something you control completely. You don’t have to convince another website owner to do anything. You don’t have to wait on anyone. Every improvement to your internal linking structure is a unilateral decision you can make today, and it affects every page on your site simultaneously. That’s a better ROI on your time than almost anything else in the SEO toolkit for a site that hasn’t done this work yet.
There’s also a technical SEO dimension to all of this that matters more as your site grows. Crawl depth, meaning how many clicks it takes Google to reach any given page from your homepage, is directly tied to internal linking structure. Pages buried four or five clicks deep get crawled less frequently and are treated as lower priority. A strong internal linking structure flattens your site’s architecture, so more pages are reachable in fewer clicks.
Where Most Contractors Should Start
If this feels like a lot, start with three things. First, check whether your five most important service pages are each being linked to from at least three other places on your site besides the navigation. If they’re not, find the natural places to add those links this week. Second, look at your last ten blog posts and see which service pages they could honestly link to. Add those links. Third, when you publish your next post, build the linking in from the start instead of treating it as optional.
None of that requires a tool, an agency, or a technical background. It requires knowing what your most important pages are and making a consistent habit of pointing other pages toward them. That’s the core of it. Everything else, the anchor text variation, the silo structures, the crawl depth optimization, layers on top of those basics.
The sites that rank well in competitive local markets for contractor services almost always have this figured out. Not perfectly, but intentionally. Someone made decisions about which pages mattered most and built a structure that communicates that to Google. That’s not magic. It’s just maintenance that most people skip because it’s invisible.
Think of internal links as the hallways of your website. When they’re planned well, visitors find what they need and Google understands which pages matter most. When they’re not, your best service pages end up stuck in a back room nobody visits.
