What Is a Backlink and Why Do Backlinks Matter for SEO?

Backlinks are one of Google's most important ranking signals — but most business owners don't understand them. Here's a plain-English explanation and a realistic link-building strategy.

Most small business owners I speak with have heard the word “backlinks” thrown around, usually by someone trying to sell them something. They nod along, not wanting to admit they’re not entirely sure what it means — and honestly, that’s completely understandable. SEO has a habit of wrapping simple ideas in intimidating language. So let’s strip that away. Backlinks are one of the most powerful factors in how Google decides where your website shows up in search results, and once you understand what they actually are, you can start doing something practical about them.

A backlink is simply a link from one website to another. When a local newspaper writes a piece about your business and includes a link to your website, that’s a backlink. When a blogger recommends your services and clicks through to your site, that’s a backlink. When a business directory lists your company with a link to your homepage, that’s a backlink too.

From Google’s perspective, a backlink is a vote of confidence. It’s one website saying to Google: “This place is worth visiting.” The more credible the site doing the linking, the more that vote counts. A link from a respected industry publication carries far more weight than a link from a spammy directory nobody’s ever heard of.

Google’s own documentation makes clear that links remain one of the key signals their algorithms use to determine the relevance and authority of a page. This has been true since the very beginning of Google, and despite countless algorithm updates, it’s still true today.

Think of it this way. If you’re new to an area and you ask ten different locals for a restaurant recommendation, and eight of them mention the same place, you’re probably going to trust that recommendation. Google works on a similar principle. When many reputable websites link to your page, Google interprets that as a signal that your content is trustworthy and worth ranking highly.

This is why two websites with otherwise identical on-page content can rank very differently — the one with stronger backlinks almost always wins. According to research from Ahrefs, over 90% of pages get zero organic traffic from Google, and a significant factor separating the ones that do rank from those that don’t is their backlink profile.

It’s also worth knowing that not all backlinks are equal. Quality matters far more than quantity. Ten links from relevant, authoritative websites in your industry will outperform a hundred links from low-quality or unrelated sites every time.

This is where a lot of businesses get into trouble. In the early days of SEO, people gamed the system by buying links in bulk or participating in link schemes. Google got wise to this quickly, and today those tactics don’t just fail — they can actively harm your rankings.

A good backlink typically comes from a website that:

  • Has genuine traffic and a real audience
  • Is topically relevant to your business or industry
  • Links to you naturally within content, rather than in a list of unrelated links
  • Has its own strong backlink profile

Moz’s Beginner’s Guide to Link Building is one of the best free resources I’d point anyone to if they want to understand this in more depth. They’ve been studying this longer than most.

Links to be wary of include anything bought in bulk from link farms, links from websites with no real content or obvious spam, links from sites completely unrelated to your industry, and links using over-optimised anchor text that looks unnatural. Google Search Console has a Disavow tool that lets you tell Google to ignore certain links pointing to your site — but ideally you never need to use it.

The Concept of Domain Authority

You’ll often hear people talk about “Domain Authority” or “Domain Rating” — these are metrics created by tools like Moz and Ahrefs to estimate how powerful a website’s backlink profile is on a scale of 0 to 100. They’re not Google metrics, but they’re useful proxies. A link from a site with a high domain authority is generally worth more than one from a newer or weaker site.

Team reviewing backlink profile

Before you do anything else, it’s worth knowing where you currently stand. There are a few ways to check.

The most straightforward free option is Google Search Console. Under the “Links” section, you can see which external sites are linking to you, which pages on your site are linked most often, and what anchor text is being used. It’s not exhaustive, but it gives you a solid starting point.

For a more complete picture, tools like Ahrefs and SEMrush offer backlink analysis features. These paid tools show you not just your own links but your competitors’ as well — which is extremely useful when you’re building a strategy. You can see exactly which sites are linking to businesses similar to yours, then target those same sites.

In my experience, most small business owners are surprised by what they find. Often there are a handful of decent links they’d forgotten about, and a few low-quality ones they’d never noticed. Understanding your starting point makes everything else clearer.

Right, this is the part most people want to get to. How do you actually get good backlinks without spending a fortune or doing anything dodgy?

The honest answer is that link building takes time and consistency. There’s no shortcut that works sustainably. But there are several approaches that genuinely deliver results for small businesses.

Local PR and press coverage. Getting mentioned in local news websites, business journals, or community blogs almost always results in a backlink. If you do something genuinely newsworthy — launch a new service, win an award, support a charity — reach out to local publications. A story in a regional news site with a link to your website is worth more than most people realise.

Business directories and citations. Getting listed on relevant, reputable directories is one of the easiest wins. Google Business Profile, Yelp, Yell, Checkatrade (if relevant to your industry), and niche-specific directories all count. These aren’t the most powerful links, but they establish credibility and consistency, especially for local SEO.

Creating genuinely useful content. This is the long game, but it works. When you publish content that answers real questions — like this article — other websites naturally link to it as a reference. Search Engine Journal calls this “earning” links rather than building them, and there’s a real distinction. Earned links are more durable and more trustworthy in Google’s eyes.

Guest posting. Writing a useful article for another website in your industry or a complementary field, with a link back to your site, is a legitimate and effective tactic. The key is to make the content genuinely valuable — not a thinly veiled advert. I’d suggest reading Yoast’s take on guest blogging for a grounded perspective on how to approach this without cutting corners.

Supplier and partner links. If you work with other businesses, ask whether they’d be willing to mention you on their website — and offer to do the same. Many businesses have “partners” or “suppliers” pages, and a link from a well-established business in your supply chain is genuinely valuable.

Reclaiming lost or unlinked mentions. Sometimes websites mention your business without linking to you. Tools like Ahrefs and SEMrush can help you find these. A polite email asking them to add a link is often all it takes, and it works more often than you’d expect.

How Long Does It Take to See Results?

This is the question I get asked more than any other. The realistic answer is: three to six months before you start seeing meaningful movement, and twelve months or more before a sustained link-building effort shows its full impact on rankings.

I know that’s not the instant-results answer people want to hear. But it’s the truth. Google Analytics and Google Search Console are your friends here — track your organic traffic and keyword positions month by month, and you’ll see the gradual upward trend that comes from doing this properly. Patience isn’t the most exciting SEO advice, but it’s the most honest.

The good news is that the results, once they come, tend to be durable. A solid backlink profile doesn’t disappear overnight. Unlike paid ads that stop the moment you stop paying, the authority built through links compounds over time.

Backlinks are powerful, but they’re not the whole picture. Google uses hundreds of signals to rank pages, and backlinks work best when the rest of your SEO is in good shape. If your website is slow to load, difficult to navigate on mobile, or has thin and unhelpful content, backlinks alone won’t get you to page one.

That’s why I always recommend sorting out the fundamentals first. My on-page SEO guide covers the technical and content basics that need to be in place before a link-building strategy really starts to move the needle. Think of on-page SEO as the foundation and backlinks as what you build on top of it.

The two work together. A well-optimised page with strong backlinks pointing to it is the combination that consistently ranks well. Neither alone is as effective as both together.

Understanding backlinks is one thing — putting together a practical strategy for your specific business is another. Every industry is different, every business has different opportunities, and there’s no one-size-fits-all approach.
