What Is a Backlink — And How Do You Get Good Ones?
If you've read anything about SEO, you've encountered the word "backlinks." They're consistently described as one of the most important ranking factors in Google's algorithm — which is true. They're also frequently misunderstood, and the tactics people use to build them range from genuinely effective to actively harmful.
This guide explains what backlinks actually are, why they matter, and how small businesses can earn good ones without resorting to shortcuts that can get your site penalized.
What a Backlink Is
A backlink (also called an inbound link or incoming link) is a hyperlink on someone else's website that points to yours. When a respected industry blog writes an article and links to a resource on your site, that's a backlink. When a local news site mentions your business and includes a link to your homepage, that's a backlink.
Google's founders built the original PageRank algorithm around a simple idea: if a lot of other websites link to a page, that page is probably trustworthy and valuable. A link from one site to another is effectively a vote of confidence. The more high-quality votes you accumulate, the more authority Google assigns to your site — and the better you rank.
That was 1998. The logic still holds in 2026, though Google's understanding of link quality has become vastly more sophisticated.
Why Quality Matters Far More Than Quantity
Not all backlinks are created equal. A single link from a nationally recognised news website is worth more than a hundred links from obscure directories no one uses. Google evaluates backlinks on multiple dimensions:
Authority of the linking site. A link from the BBC, a major university, or a well-established industry publication carries far more weight than a link from a newly created blog with no traffic.
Relevance. A link to your plumbing business from a home improvement blog is more valuable than a link from a fashion website. Contextual relevance signals to Google that the link makes sense.
The anchor text. The clickable text of the link gives Google a clue about what your page is about. A link that says "web design for small businesses" pointing to your services page is more informative than one that just says "click here."
Natural vs. manipulative. Google can identify patterns that suggest links were purchased, exchanged artificially, or generated through spam. These links don't just fail to help — they can actively hurt your rankings.
The takeaway: ten high-quality, relevant backlinks will outperform two hundred low-quality ones every time. And two hundred spammy ones can get you hit with a manual penalty.
How Small Businesses Can Earn Backlinks
1. Create content worth linking to
This is the foundation of sustainable link building. Content that provides genuine value — original research, comprehensive guides, tools, or resources that answer a question better than anything else online — attracts links naturally over time.
For Twin Fin Studio, that might be a thorough guide to local SEO in Belgium that other marketing blogs reference, or a free tool that businesses use to check something about their online presence. Content built to earn links performs better than content built purely to rank for keywords.
2. Get featured in local press and directories
Local news sites, business journals, and community organisations frequently cover local businesses — particularly around milestones like launches, events, awards, or interesting stories. A mention in a local paper's website that includes a link is a legitimate, quality backlink.
Also get listed in industry and local directories that are genuinely used and respected. These aren't just citations — relevant directory listings often carry real link equity. We cover the most important ones for local businesses in our local citations guide.
3. Build partnerships with complementary businesses
If you work with web hosting companies, graphic designers, copywriters, photographers, or other service providers that complement what you do, there's often a natural opportunity for mutual mentions. A case study of a project you collaborated on, published on both sites, generates a relevant backlink from a real business with an established web presence.
This works best when it's genuinely authentic — don't approach it as a link scheme, approach it as collaboration that happens to have an SEO benefit.
4. Write guest posts for relevant publications
Contributing an article to an industry publication or reputable blog in your field typically includes an author bio with a link to your site. One well-placed guest post on a site your target clients actually read is worth more than a dozen low-effort submissions to generic article directories.
The bar for this is: would you be proud to have your name on this site? If yes, the guest post is worth pursuing.
5. Get quoted as an expert
Journalists and bloggers regularly look for expert quotes via platforms like HARO (Help a Reporter Out) or Qwoted. If you're in a field where you have genuine expertise, signing up and responding to relevant queries can earn you links from high-authority media publications — exactly the kind of link that moves the needle.
6. Reclaim unlinked mentions
Sometimes people mention your business by name without linking to you. A quick Google search for your business name (in quotes) will surface these mentions. When you find one — especially on a reputable site — send a polite email to the author asking if they'd be willing to add a link. Most will say yes, because it makes the mention more useful for their readers anyway.
What to Avoid
Buying links. Google's guidelines explicitly prohibit buying or selling links that pass PageRank. This has been true for years and enforcement has gotten more sophisticated. Paid links that are identified — either by algorithm or by manual review — can result in a penalty that's painful to recover from.
Link exchanges. "I'll link to you if you link to me" is a practice Google understands well. The occasional genuine editorial exchange between relevant sites is fine, but systematic reciprocal linking is a red flag.
Private Blog Networks (PBNs). Networks of sites created specifically to sell links. Increasingly easy for Google to detect, and high-risk if caught.
Low-quality directory spam. Mass submissions to hundreds of irrelevant directories don't help and can create a spammy link profile that Google devalues your site for.
Monitoring Your Backlinks
You can track your backlink profile using free tools like Google Search Console (which shows who's linking to you) or Ahrefs Backlink Checker (limited but useful free version). Knowing who links to you helps you identify new opportunities, spot potentially harmful links, and understand which content is earning the most links.
If you find links from genuinely spammy sites pointing to yours, you can use Google's Disavow Tool to ask Google to ignore them — though this is rarely necessary unless you've been actively targeted with negative SEO.
The Long Game
Backlink building is slow, which is why so many businesses look for shortcuts. But the shortcuts carry risks that the slow approach doesn't. A site that earns twenty genuine, high-quality backlinks per year from relevant, reputable sources will build a durable ranking position that competitors with spammy link profiles simply can't match.
Combined with solid on-page SEO and quality content, a steady backlink-building strategy is one of the most reliable ways to improve your search visibility over the long term.
