Backlinks — links from other websites pointing to yours — are still one of the strongest signals Google uses to rank pages. But most link-building advice is written for agencies and enterprise sites with big budgets. Here's what actually works for small businesses.

The good news: small businesses have advantages that large sites don't. You have real relationships, real locations, real expertise, and a genuine story. Those things translate into links in ways that scaled agency tactics don't.

Google's original insight was that if many authoritative websites link to a page, that page is probably trustworthy and valuable. That logic still holds. Links act as third-party endorsements — they tell Google that real people and real organisations think your content is worth referencing.

Beyond rankings, links also drive direct referral traffic. A well-placed link from a relevant industry site or local newspaper can send real visitors who are already interested in what you offer.

Links also matter for AI search. Systems like ChatGPT and Perplexity draw on the web's link graph when determining which sources to cite. A site with more credible, relevant links pointing to it is more likely to be cited as an authoritative source in AI responses. This overlaps with AEO (Answer Engine Optimisation) — see the full guide on getting cited by AI.

Quality vs quantity

Ten years ago, volume was what mattered. Today, one link from a relevant, respected site in your industry is worth more than 100 links from unrelated directories.

What makes a link high-quality:

  • Relevance: the linking site is in the same industry or location as you. A link from a local trade association means more to a plumber than a link from a recipe blog.
  • Authority: the linking site is trusted and itself has links from credible sources. Domain Rating (DR) in Ahrefs or Domain Authority (DA) in Moz are proxy metrics — not perfect, but useful.
  • Editorial placement: the link is in the body of a piece of content, not buried in a footer or sidebar. Editorial links pass more value.
  • Anchor text: the words used to link to you. Branded anchor text ("Bisyri") and descriptive anchor text ("web designer in Iceland") both signal something about your site.
  • Dofollow vs nofollow: dofollow links pass ranking authority. Nofollow links are marked to tell Google not to pass authority. Most editorial links are dofollow. Most social media links and many directory listings are nofollow — still worth having for traffic and visibility, but don't count them the same way.

Easy wins first

Before doing anything complex, get the basics in place. These are fast, free, and often overlooked:

1. Google Business Profile

Your GBP listing links to your website. It's a high-authority, relevant citation. If you haven't claimed and optimised it, do that first — see the GBP optimisation guide for the full process.

2. Industry and local directories

Every industry has legitimate directories. For local tradespeople, Checkatrade, Trustmark, or similar. For professional services, industry association directories. For local businesses, the local chamber of commerce website. These are often nofollow, but they provide consistent NAP (Name, Address, Phone) signals for local SEO and drive direct traffic.

Stick to directories that are actually relevant and where humans might genuinely look. Avoid mass directory submissions to hundreds of generic sites — that's 2010 SEO and it's more likely to hurt than help.

3. Supplier and partner websites

If you use suppliers, manufacturers, or tools that list their customers or partners, get listed. If you're an accredited installer of a product, the manufacturer's "find a dealer" page is a relevant, often authoritative link. These relationships already exist — it's just a case of asking.

4. Professional memberships

Any trade body, professional association, or accreditation you hold should be linking to your site. Many membership organisations list their members with links — if yours does, make sure you're on it and the link points to the right page.

Local link building

For local businesses, local links carry extra weight. Google uses them as evidence that you're a real, established part of the local business community.

Local news and publications

Local newspapers, blogs, and community publications frequently write about local businesses — especially if there's a news angle. A new opening, a charity initiative, a local award, an interesting backstory. You don't need to pitch a national outlet. A link from a local news site with genuine community readership is excellent for local SEO.

Reach out to local journalists when you have something genuinely newsworthy. "We're a local business that's been here for 10 years" isn't a story. "We just won a regional award" or "We're the first business in town to do X" is a story.

Sponsorships

Sponsoring local events, sports teams, charities, or schools often comes with a link on their website. The link quality depends on the site's authority, but even a modest local organisation's website provides a relevant, location-specific citation. Don't do this only for the link — but if you're already sponsoring local causes, make sure you're getting the link.

Local business associations

Chambers of commerce, business improvement districts, and local business networks often have member directories with dofollow links. The membership cost is often reasonable, and the link is just one of the benefits.

Local blog and community sites

Many towns and neighbourhoods have community websites, Facebook groups with external pages, or local blogs. Contributing a guest article, being interviewed, or simply being mentioned as a local resource can generate links with strong local relevance signals.

Content-based links

The most scalable link-building strategy is creating content other people want to link to. This works especially well when you have genuine expertise that isn't available elsewhere.

Industry guides and resources

A genuinely comprehensive guide to something in your industry is the kind of content that earns links naturally. Other people in your space — bloggers, journalists, other businesses — will link to it when writing about the same topic. The key word is "genuinely" — thin content doesn't earn links, and the bar is higher than it used to be.

Free tools

If you can build something useful that people in your industry use, it generates links passively. These don't have to be complex — a pricing calculator, a checklist generator, a quiz. Useful tools get bookmarked and linked to without you having to ask.

Original data and research

If you have access to data or can run a survey relevant to your industry, publishing the results is highly linkable. Journalists and bloggers need data sources — if you provide one, you get cited. Even small-scale surveys can work if the findings are genuinely interesting.

Case studies

Detailed case studies of how you helped a client solve a specific problem are link-worthy in industry circles. They're also useful for demonstrating expertise to potential clients. A client who features in a case study often shares it — which may generate links from their own network.

Partnerships and suppliers

Your business network is an underused link-building resource. Think about:

  • Complementary businesses: businesses that serve the same audience but don't compete with you. A web designer might partner with a copywriter or photographer. Each business can reference the other on their site.
  • Clients: if you've done good work for a client and they have a website, ask if they'd be willing to mention you. A testimonial page with a link, or a "designed by" credit, is both a link and social proof.
  • Suppliers: as mentioned above — if your suppliers list their customers, make sure you're on the list.

These are relationships-based links, which means they tend to be relevant and genuinely editorial — exactly what Google values most.

Small-scale PR

You don't need a PR agency to get press coverage. A few tactics work well at small scale:

HARO / journalist enquiries

Journalists regularly send out requests for expert commentary via platforms like Qwoted, SourceBottle, and similar services. If you respond quickly with a relevant, quotable answer, you'll often be cited with a link. Set aside 15 minutes a day to scan these requests in your industry. The hit rate is low, but the links you do get are high-authority.

Expert commentary

When something relevant happens in your industry, reach out proactively to journalists covering that beat with your take. A flooring company owner commenting on housing market trends. A web designer commenting on a major website redesign. Relevant expertise + a timely hook = coverage.

Guest posting

Writing an article for another site in your industry or a complementary niche can generate a quality link and direct traffic. Focus on sites where your target audience actually reads — not just any site that accepts guest posts. A well-placed guest post on an industry publication your customers trust is worth more than ten posts on random blogs.

What to avoid

Some link-building tactics are either useless or actively dangerous:

  • Buying links: violates Google's guidelines, risks a manual penalty. Not worth it.
  • Link farms and private blog networks (PBNs): networks of low-quality sites set up solely to sell links. Google detects them. The short-term ranking boost often leads to a penalty that's hard to recover from.
  • Mass directory submissions: submitting to hundreds of irrelevant directories used to work. Now it's at best ignored and at worst a negative signal.
  • Reciprocal link schemes: "I'll link to you if you link to me" at scale is a link scheme. Natural, occasional reciprocal links between genuinely related sites are fine — organised schemes are not.
  • Comment spam: leaving links in blog comments. Most are nofollow anyway, and spammy behaviour can get your site flagged.

Tracking your links

Once you're actively building links, you need to track what you have and what's working. The free tier of Ahrefs' backlink checker shows your top 100 backlinks, their Domain Rating, and anchor text. That's enough to start.

Check Google Search Console's Links report (under the main navigation) for a full list of sites linking to you — it's less detailed than Ahrefs but it's what Google actually sees.

Things to look for:

  • New links appearing after outreach — to see what's working
  • Lost links — pages that used to link to you and now don't (the source page may have been updated or removed)
  • Unexpected links from irrelevant or low-quality sites — in rare cases worth disavowing

See the keyword research guide for how to use Ahrefs Free to analyse competitors' link profiles and find gap opportunities.

The short version

For most small businesses, link building breaks down into three phases: first, claim all the easy citations (GBP, industry directories, supplier pages, memberships). Second, build local links through community involvement, sponsorships, and outreach to local press. Third, earn natural links by creating genuinely useful content and contributing expertise to your industry. Skip the shortcuts — they're not worth the risk. Build links the same way you build business relationships: with something of genuine value to offer.
