Link Building: What Works, What Doesn’t, and What to Avoid

Links from other websites to yours are still one of the strongest ranking signals Google uses. That hasn’t changed. What has changed is how you need to get them. The tactics that worked five years ago, mass guest posting, directory submissions, buying links from Fiverr, will now either do nothing for you or actively damage your rankings.

 

According to analysis by Backlinko, the number one result on Google has 3.8 times more backlinks than positions two through ten. And research by Ahrefs found that 94% of all web pages have zero external backlinks pointing to them. So links clearly matter, and most websites don’t have enough of them.

 

The question for most UK businesses isn’t whether link building matters. It’s how to do it without wasting money or getting penalised. This guide covers what actually works in 2026 and what to stay well away from.

 

What Is Link Building?

 

Link building is the process of getting other websites to link to yours. Each link acts as a vote of confidence in Google’s eyes. The more relevant, trustworthy websites that link to you, the more authority your site builds, and the higher it can rank for competitive search terms.

 

Not all links are equal though. A link from a respected industry publication or a well-known news site carries far more weight than a link from a random blog nobody reads. Google’s algorithm evaluates the quality, relevance, and context of every link. A single link from a highly relevant, authoritative source can do more for your rankings than fifty links from low-quality directories.

 

Why Do Backlinks Still Matter for SEO?

 

Backlinks remain one of Google’s top ranking factors because they’re hard to fake at scale. Anyone can write content and optimise their title tags. But getting other reputable websites to voluntarily link to you requires your site to actually be worth linking to. That’s why Google treats links as a trust signal.

 

Links also help Google discover new pages. When Googlebot crawls a page on another site and finds a link to yours, it follows that link and crawls your page too. This is one of the primary ways Google finds and indexes content across the web.

 

Beyond rankings, links drive direct referral traffic. A well-placed link on a popular industry blog or news article can send a steady stream of relevant visitors to your site, people who are already interested in what you do.

 

What Makes a Good Backlink?

 

There are four things that determine whether a backlink is valuable:

 

Relevance. A link from a website in your industry or a closely related field carries more weight than a link from an unrelated site. If you’re a London solicitor, a link from a legal directory or a law-related publication is far more valuable than one from a random tech blog.

 

Authority. Links from well-established, trusted websites pass more ranking power than links from new or low-quality sites. Think national newspapers, industry bodies, universities, government sites, and respected trade publications.

 

Context. A link embedded naturally within relevant content (an editorial link) is worth more than a link sitting in a sidebar, footer, or author bio. Google looks at the text surrounding the link to understand its context.

 

Anchor text. The clickable text of the link gives Google a signal about what the linked page is about such as “what is SEO” ? Natural anchor text that describes the destination page is ideal. Over-optimised anchor text (using your exact target keyword every time) looks manipulative and can trigger a penalty.

 

Link Building Strategies That Work in 2026

 

The approaches that consistently deliver results in 2026 are the ones that focus on earning links through genuine value rather than tricking or buying your way to them.

 

Create content worth linking to. This sounds obvious, but it’s where most link building campaigns should start. If you have a genuinely useful guide, an original piece of research, a helpful tool, or a comprehensive resource on a topic in your industry, other websites will link to it naturally over time. This is why creating content with purpose matters so much. A blog post that says nothing new won’t attract links. A post that provides data, answers questions nobody else has answered, or takes a clear position on an industry topic will.

 

Digital PR. This has become the dominant link building tactic for UK businesses with budget. It involves creating newsworthy content (original research, surveys, data analysis, expert commentary) and pitching it to journalists. When a journalist picks it up, you get an editorial link from a high-authority news or industry publication. According to a 2026 survey of 518 SEO professionals, digital PR is now ranked the most effective link building tactic by 48.6% of respondents.

 

Business relationships and mentions. If you supply products or services to other businesses, those businesses often have websites with partner pages, supplier lists, or case studies. Ask them to link to you. Similarly, if your brand gets mentioned online without a link (an unlinked mention), reach out and ask the author to add one. They’ve already acknowledged you, so the ask is natural.

 

Local and industry directories. Not all directories are worthless. Listings on relevant, curated directories, your local chamber of commerce, professional trade bodies, established industry directories, still carry value and help build your entity signals. The key is selectivity. A listing on your industry’s professional body is valuable. A listing on a random global directory with no editorial standards is not.

 

Guest contributions. Guest posting still works, but only when done properly. Writing a genuine, valuable article for a respected publication in your industry, where you’re contributing expertise rather than just chasing a link, can earn you a strong editorial backlink. The approach that doesn’t work is mass-produced guest posts on low-quality blogs that exist solely to sell links.

 

What to Avoid

 

This is where businesses get burned, often because they’ve hired a cheap overseas SEO provider that uses link building tactics Google has been penalising for years.

 

Buying links. Paying for links that pass ranking power is a violation of Google’s spam policies. This includes paid guest posts on blogs that exist purely to sell links, Private Blog Networks (PBNs), and any scheme where you’re exchanging money for a followed link. Google’s spam detection has improved dramatically with its SpamBrain system, and sites caught participating in link schemes can receive manual actions that tank their rankings overnight.

 

Low-quality directory spam. Submitting your site to hundreds of random directories adds no value and can create a spammy backlink profile. If a directory will accept any website regardless of relevance or quality, it’s not worth being listed on.

 

Link exchanges. “You link to me and I’ll link to you” at scale is a link scheme. Google specifically calls this out in its documentation. The occasional natural reciprocal link between genuinely related businesses is fine. Systematic exchanges are not.

 

Automated link building tools. Any tool that promises to build hundreds or thousands of links automatically is building the kind of links that will harm your site. These typically create spam comments, forum profiles, and web 2.0 pages that Google ignores at best and penalises at worst.

 

How Does Link Building Connect to AI Search?

 

Links aren’t just a Google ranking factor anymore. They influence whether AI tools cite your business too. When AI search engines like ChatGPT, Gemini, and Perplexity retrieve content to answer a question, they tend to pull from sources that are well-cited and well-linked across the web. A strong backlink profile is part of the trust signal that makes your content more likely to appear in AI-generated answers.

 

This is another reason why quality matters more than quantity. AI systems are designed to surface authoritative, trustworthy sources. A handful of strong editorial links from respected publications will do far more for your AI visibility than hundreds of low-quality links from obscure sites.

 

A Realistic Approach for UK Small Businesses

 

Most small businesses don’t have the budget for large-scale digital PR campaigns, and that’s fine. The most effective approach for smaller businesses is to focus on the fundamentals:

 

Make sure you’re listed on the relevant directories and professional bodies in your industry. Claim your profiles on platforms like Google Business Profile, Yell, Bark, and any trade-specific directories. Build relationships with complementary businesses and look for natural linking opportunities. Create one or two genuinely useful pieces of content that could attract links over time. And make sure your technical SEO and on-page SEO are solid, because links to a poorly optimised site are a waste.

 

If your SEO isn’t working and your on-page is solid, links are usually the missing piece. But they need to be the right links, built the right way.

Frequently Asked Questions

 

How many backlinks do I need to rank on page 1?

There’s no fixed number. It depends entirely on how competitive your target keywords are and how many (and how strong) the links are that your competitors have. For a local service business targeting terms like “plumber in Bromley,” you might only need a handful of quality links. For nationally competitive terms, you’ll need significantly more. The focus should always be on quality over quantity.

 

Can backlinks hurt my website?

Yes. Low-quality, spammy, or unnatural links can trigger a Google penalty, either through the algorithm (your rankings drop automatically) or a manual action (a Google reviewer flags your site). This is why choosing the right SEO agency matters. If you’ve inherited a toxic backlink profile from a previous agency, Google’s Disavow Tool can help, but it’s best to avoid the problem in the first place.

 

How long does link building take to show results?

Link building is a long-term strategy. You can sometimes see ranking improvements within a few weeks of earning a strong link, but meaningful, sustained results typically take three to six months of consistent effort. Links compound over time, so the earlier you start building quality links, the stronger your position becomes.

 

Should I focus on link building or content first?

Content first, always. You need pages worth linking to before you start asking for links. Get your on-page SEO right, create useful content, then pursue links to those pages. Building links to thin, poorly optimised pages is a waste of effort.

 

Is it worth paying for link building services?

It can be, if the agency or provider is building genuine, high-quality links through ethical methods. Be very cautious of anyone offering hundreds of links for a low monthly fee, as those links are almost certainly low quality. A reputable provider will be transparent about how they build links, what sites they target, and how many links you can realistically expect per month for your budget.
