What Is a Backlink? A Simple Guide for Small Business Owners

A backlink is a link from one website to another — specifically, a link on someone else's site that points back to yours. Search engines like Google treat backlinks as a kind of vote of confidence: if other sites link to you, especially reputable ones, it signals that your content is useful or trustworthy enough to be worth referencing. The more relevant, high-quality backlinks a page has, the better it tends to rank in search results.

That's the short answer. But if you run a small business and you've heard the term thrown around by marketers or SEO tools without a clear explanation, it's worth understanding how backlinks actually work, why they matter, and — just as importantly — why not all of them are worth chasing.

How do backlinks actually work?

When another website links to yours, it passes along a small signal of trust to search engines. Google's algorithms were originally built around the idea that links act like citations in an academic paper — the more a page is cited by others, the more authoritative it's assumed to be.

In practice, this means a link from a well-known industry publication or a respected local news site carries more weight than a link from a random, low-quality directory. Google also looks at the context: a link from a page about your industry, using relevant surrounding text, is more valuable than a link buried in an unrelated page's footer.

It's worth noting that backlinks aren't the only ranking factor. They work alongside things like on-page content quality, site structure, and technical health. But they remain one of the more influential signals, especially for competitive keywords where many businesses are trying to rank for the same terms.

What does "anchor text" mean?

Anchor text is the clickable, visible words in a hyperlink — for example, in a link that says "best plumbers in Austin," the anchor text is "best plumbers in Austin." Search engines use anchor text as an extra clue about what the linked page is about, so relevant, natural anchor text tends to help more than vague text like "click here."

Do-follow vs. no-follow links

Not every backlink passes on the same kind of signal. A "do-follow" link is the default type — it tells search engines to follow the link and pass along some measure of trust and authority to the page it points to. A "no-follow" link includes a small piece of code telling search engines not to pass along that credit, even though the link still works for anyone who clicks it.

Many legitimate sites use no-follow links by default for things like comments sections, forum posts, or sponsored content, simply to avoid endorsing content they don't control. This doesn't mean no-follow links are worthless — they can still send real visitors to your site and contribute to a natural-looking link profile. But if your goal is specifically to build search engine authority, do-follow links from relevant, reputable sites tend to matter more.

Why do backlinks matter for small businesses?

Backlinks matter because they help search engines decide how much to trust and rank your website compared to competitors. For a small business competing against bigger, more established companies, a handful of strong, relevant backlinks can meaningfully improve visibility for local or niche search terms.

This matters even more for small and local businesses because your competitors for a term like "roof repair near me" or "dentist in [city]" may already have years of press mentions, supplier listings, or partner links pointing to their site. Building a few solid backlinks of your own — from a local chamber of commerce, an industry association, or a supplier — helps level that playing field over time.

Backlinks also drive direct traffic. Beyond the SEO signal, a link on another site is a doorway people actually click through. A mention in a local news article or a partner's resource page can send real visitors to your site, not just search engine credit.

What are examples of good backlinks?

A good backlink typically comes from a site that is relevant to your industry or location, has its own genuine audience, and links to you in a natural, editorial context rather than a paid or spammy one. A few common examples for small businesses include:

• A local newspaper or news site mentioning your business in a story
• An industry association or trade group listing you as a member
• A supplier, partner, or manufacturer linking to your business as a retailer or service provider
• A guest post or expert quote you contributed to another site in your niche
• A local chamber of commerce or business directory with genuine editorial standards

What makes a backlink low-quality or risky?

A low-quality backlink usually comes from a site with little relevance to your business, thin or spammy content, or a pattern of links that were clearly bought or automatically generated rather than earned. Google has taken action against manipulative link schemes for years, and sites caught buying large volumes of irrelevant links can see their rankings hurt rather than helped.

Signs of a risky link include: it comes from a directory that exists purely to sell links, it's part of a large batch of identical links across unrelated foreign-language sites, or it was acquired through a "link exchange" service promising guaranteed placements. A handful of these won't necessarily sink you, but building a strategy around them is a gamble that can backfire.

How do you get backlinks as a small business?

The most reliable way to get backlinks is to earn them by being genuinely worth linking to — through real relationships, useful content, and visibility in your local or industry community — rather than by buying links in bulk. A few realistic starting points for a small business:

1. Get listed with suppliers and partners. If you sell a product or work with distributors, ask if they can link to your site from their "where to buy" or partner pages.
2. Reach out to local media. Local news outlets often cover small business openings, milestones, or community involvement — a quick pitch can lead to a mention and a link.
3. Join relevant associations. Trade groups, chambers of commerce, and certification bodies often list members with a link to their website.
4. Write something worth citing. A genuinely useful guide, local resource, or original data on your site gives other people a reason to link to it naturally.
5. Offer expert commentary. Journalists and bloggers regularly look for quotes from real business owners — being available and responsive can earn you a mention and a link.

If you'd rather not chase links one by one, it's also worth understanding the difference between doing this yourself and paying an agency or service to build links on your behalf, since outsourcing link building comes with its own trade-offs in cost and control.

Backlinks are one piece of a much bigger picture, though. They sit alongside things like having clear, well-structured content on your own site — which is part of what search engine optimization as a whole is about, and something you have far more direct control over than what other websites choose to link to.

How do you check who's already linking to you?

Before you start building new backlinks, it helps to know what you already have. Free tools like Google Search Console show you a list of external sites currently linking to your pages, along with which of your pages get the most links. Paid SEO tools such as Ahrefs, Semrush, or Moz go further, letting you see competitor backlinks, estimate the authority of linking sites, and spot low-quality or spammy links that might be worth disavowing.

Reviewing this list periodically also helps you catch opportunities — for example, if a supplier or local publication already mentions your business by name without linking, a quick email asking them to add a link is often an easy win. Checking your existing backlinks every few months is generally enough for most small businesses; there's rarely a need to monitor it daily.

Are backlinks still important with AI search engines?

Yes — backlinks still matter, but AI-powered search tools like ChatGPT and Perplexity also weigh factors like how clearly your content answers a question, not just how many sites link to it. These tools tend to favor content that's well-structured, directly answers common questions, and demonstrates real expertise, alongside traditional trust signals like backlinks.

This is part of why link-building and content quality are increasingly treated as connected rather than separate efforts. A page that earns backlinks because it's genuinely useful is also more likely to be the kind of page an AI search engine chooses to cite.

Ofte stillede spørgsmål

Do backlinks cost money?

Not necessarily. Many valuable backlinks are earned for free through relationships, media coverage, or genuinely useful content. Paid link-building services do exist, and prices vary widely, but buying links carries risk if the links come from low-quality or spammy sources.

How many backlinks does a small business need?

There's no fixed number — it depends on your industry and competition. A local business in a low-competition niche might rank well with a handful of strong, relevant links, while a business in a crowded market may need many more over time.

Can too many backlinks hurt my site?

It's not the quantity that's risky, it's the quality and pattern. A sudden spike of low-quality, irrelevant, or clearly purchased links can raise flags with search engines, while a steady accumulation of relevant, earned links is generally safe and beneficial.

What's the difference between a backlink and an internal link?

A backlink comes from an external website pointing to yours, while an internal link connects two pages within your own website. Both help search engines understand and navigate your site, but they serve different purposes — internal links help distribute authority and context across your own pages, while backlinks signal trust from outside sources.

Should I focus on backlinks before fixing my own website's SEO?

Generally no — it's worth making sure your own site's content and technical setup are solid first, since backlinks pointing to a page with thin content or technical problems won't do much good. Many small business owners start with a basic review of their site's on-page and technical health before investing time in outreach or link building.
