What Is a Backlink?
A backlink, also called an inbound link or incoming link, is a hyperlink placed on one website that points to a page on a different website. If a respected industry blog publishes an article and links to your services page, that link is a backlink to your site. Each one acts as a recommendation, telling both readers and search engines that your content is worth visiting.
Search engines such as Google count backlinks as a core part of how they rank pages. The logic is simple. When many credible sites link to a page, it signals that the page is useful, trustworthy, and authoritative. This idea grew out of Google's original PageRank model, and although the algorithm is far more sophisticated today, links remain central to how authority is measured.
Not every link is treated the same way. A link can carry full ranking value, or it can include a "nofollow", "sponsored", or "ugc" attribute that tells search engines not to pass authority. Links from editorial content tend to count for more than links buried in footers or comment sections. Understanding these distinctions is the first step towards building a healthy link profile, which sits at the heart of any SEO strategy.
Why Backlinks Matter
Backlinks matter because they directly influence where your pages rank in search results. Two sites with similar content and on-page optimisation will often be separated by the quality and quantity of the links pointing to them. Strong backlinks help pages climb the rankings, which in turn grows organic traffic without paying for every click the way you would with PPC.
Links also drive referral traffic in their own right. A mention on a popular South African news site or a relevant industry directory can send interested visitors straight to your pages, and those visitors often convert well because they arrive with context and trust already in place. A page that earns links and ranks well tends to lift the wider site too, because authority flows through internal links to other pages.
Just as important, backlinks build credibility. When authoritative domains vouch for you, prospective customers see your brand in good company. This compounds over time, making each new link, piece of content, and ranking position easier to win than the last.
How to Earn Quality Backlinks
Quality beats quantity every time. A handful of links from trusted, topically relevant sites will do more for your rankings than hundreds of links from low-value directories or spammy networks. Google's algorithms are designed to spot manipulative link schemes, and buying links or using private blog networks can trigger penalties that are slow and painful to recover from. White-hat link building, by contrast, earns links because the content genuinely deserves them.
The most reliable way to earn links is to create assets worth linking to: original research, practical guides, free tools, and data that other writers want to cite. Digital PR and outreach help too, where you pitch genuinely useful stories or expert commentary to journalists and editors. Guest contributions on reputable industry publications, partnerships with complementary businesses, and getting listed in credible local directories all add authoritative links the right way.
Relevance and authority should guide every link you pursue. Aim for sites in your industry or region, check that they have real traffic and editorial standards, and avoid anything that promises hundreds of links overnight.

What makes a good backlink?
Not all backlinks carry equal weight. A good backlink comes from a page that is itself relevant and authoritative, sits within the main content rather than a footer or sidebar, uses natural anchor text, and is a dofollow link that passes ranking signal. A single editorial link from a respected South African publication is worth more than dozens from low-quality directories. Relevance matters as much as authority: a link from a marketing blog to a marketing agency reads as a genuine endorsement, while an unrelated link looks manufactured. Quality and relevance beat volume every time.
How do you earn backlinks?
The durable way to earn links is to publish something worth citing: original data, a genuinely useful guide, a tool, or expert commentary that journalists and bloggers want to reference. Digital PR, guest contributions to reputable sites, and getting listed in credible industry directories all help. What to avoid is buying links or joining link schemes, which breach Google's guidelines and risk a penalty. Because good links are earned rather than bought, link building is slow, but the authority it builds is durable and hard for competitors to copy.

Do backlinks still matter for SEO in 2026?
Yes. Backlinks remain one of Google's strongest ranking signals. Quality now matters far more than quantity, so a few links from trusted, topically relevant sites help your rankings more than hundreds of low-value or spammy directory links.
How do you get quality backlinks?
Earn quality backlinks by creating link-worthy assets such as original research, practical guides, and free tools, then promoting them through digital PR and outreach. Guest articles on reputable publications and credible local directories also help. Avoid buying links, which risks penalties.
What is the difference between dofollow and nofollow links?
A dofollow link passes ranking signal (link equity) to the target page; a nofollow link tells search engines not to pass that signal. Natural link profiles contain both. Dofollow links from relevant, authoritative pages are the ones that most influence rankings.
How many backlinks do I need to rank?
There is no fixed number. A handful of links from highly relevant, authoritative sites can outrank a competitor with hundreds of weak ones. Focus on the quality and relevance of linking domains rather than a target count.
