Introduction
If you’ve been researching SEO for any length of time, you’ll have heard the word “backlinks” thrown around constantly. But what are backlinks in SEO, why do they matter so much, and — more importantly — how do you actually earn them?
In simple terms, a backlink is a link from one website to another. When a reputable website links to your content, it sends a signal to Google that your page is credible, relevant, and worth ranking. In many ways, backlinks are the currency of the web — and the businesses that earn the most high-quality ones tend to dominate the search results.
But not all backlinks are equal. A single link from an authoritative, relevant website can be worth more than hundreds of low-quality links from obscure directories. Getting this distinction right is what separates an effective backlink building strategy from one that wastes your budget — or worse, gets you penalised.
In this guide, we’ll break down everything you need to know: what backlinks are, why they remain one of Google’s strongest ranking signals, the different types you’ll encounter, and the practical strategies you can use to build a strong, sustainable link profile.
What Are Backlinks?
A backlink — also known as an inbound link or incoming link — is created when one website links to a page on another website. From Google’s perspective, every backlink your site receives is effectively a vote of confidence: another website is saying, “this content is good enough to share with my audience.”
Google’s original PageRank algorithm was built on exactly this principle. The more votes (links) a page accumulates from trustworthy sources, the more authority it carries — and the higher it’s likely to rank.
Here’s a simple way to picture it: imagine you’re looking for a reliable local plumber. If ten of your neighbours independently recommend the same person, you’re far more likely to trust that recommendation than if just one person mentioned them. Backlinks work in precisely the same way. The more credible sites that vouch for your content, the more Google trusts it.
This is also directly tied to a website’s E-E-A-T signals — Experience, Expertise, Authoritativeness, and Trustworthiness — which Google uses to evaluate content quality. A strong backlink profile is one of the clearest signals of genuine authority in your field.
Building that authority requires a joined-up approach. Our SEO growth service combines backlink acquisition with technical foundations and content strategy to deliver lasting results.
Why Are Backlinks Important for SEO?
They Improve Your Search Rankings
Backlinks remain one of Google’s most powerful ranking factors. Pages with strong, relevant backlink profiles consistently outrank pages with weak ones — all other things being equal. When authoritative websites link to your content, it signals to Google that your page deserves to be seen.
They Build Domain Authority
Every time a reputable site links to you, it passes a portion of its own authority to your site — a concept often referred to as “link equity.” Over time, accumulating links from high-quality referring domains strengthens your overall Domain Authority (DA), which influences how well your entire site ranks across all your target keywords.
They Drive Referral Traffic
Beyond SEO, backlinks bring direct visitors. When your content is featured on a popular industry blog, news site, or resource page, their audience can click through to your website — generating qualified traffic that costs you nothing per click and continues delivering value long after the link was placed.
Unlike paid ads, which stop the moment your budget runs out, referral traffic from backlinks compounds over time.
They Help Google Find and Index Your Content
Search engine crawlers discover new pages by following links across the web. If your new blog post or service page earns a backlink from an established site, Google’s crawlers are likely to find and index it far faster than if it had no external links pointing to it at all. This is particularly valuable when launching new content or service pages.
They Support Competitive Intelligence
Analysing your competitors’ backlink profiles reveals which sites are linking to them — and, by extension, which sites might be willing to link to you too. This is the foundation of many successful outreach campaigns and a core part of any serious link building strategy in Kent.
Types of Backlinks You Need to Know
Dofollow Backlinks
These are the standard type of link — they pass link equity from the linking site to yours, directly contributing to your rankings. Most links you’ll aim to earn through outreach, content, and PR campaigns will be dofollow.
Nofollow Backlinks
A nofollow link includes a tag instructing search engines not to pass ranking value. Whilst they don’t directly impact your rankings, they still have value: they can drive referral traffic, increase brand awareness, and contribute to a natural-looking link profile. Links from social media platforms and many news sites tend to be nofollow.
Editorial Backlinks
These are the gold standard. An editorial backlink is earned organically — another site links to your content because they genuinely find it valuable, without any form of exchange or payment. These links are the most trusted by Google because they’re the hardest to manufacture.
If you produce genuinely helpful, well-researched content — whether that’s original data, in-depth guides, or expert commentary — editorial backlinks will follow naturally over time.
Guest Post Backlinks
Contributing a well-written article to a relevant, reputable website in your industry is one of the most reliable ways to earn a dofollow backlink. When done properly — targeting quality publications and creating genuinely useful content — guest blogging remains an effective strategy. Avoid low-quality “guest post farms” that exist purely for link exchange; these offer little SEO value and can attract penalties.
Directory and Resource Page Links
Submitting your business to reputable industry directories and resource pages can generate steady, low-effort backlinks. Whilst these rarely carry the same weight as editorial or guest post links, they’re still useful — particularly for local SEO and brand visibility. Think professional associations, Chamber of Commerce listings, and sector-specific directories.
Broken Link Building
This involves finding broken links on other websites (links pointing to pages that no longer exist) and suggesting your own relevant content as a replacement. It’s a genuine value exchange — you’re helping a webmaster fix their site whilst earning a backlink in return.
What Makes a High-Quality Backlink?
Not every backlink is worth pursuing. Here’s what separates a genuinely valuable link from one that adds little — or actively causes harm:
Quality Signal | What to Look For |
|---|---|
Relevance | The linking site covers topics related to your industry or niche |
Authority | The linking domain has strong trust signals and a healthy backlink profile of its own |
Placement | The link sits within the main body of content, not tucked away in a footer or sidebar |
Anchor Text | The clickable text is descriptive and relevant without being keyword-stuffed |
Editorial Context | The link adds genuine value to the surrounding content |
Uniqueness | Links from a diverse range of referring domains are more valuable than multiple links from a single source |
A backlink from a well-respected industry publication will do far more for your rankings than fifty links from obscure, unrelated websites. Quality consistently outweighs quantity.
This is why the most sustainable approach to link building focuses on relationships and content rather than shortcuts — a principle that underpins the backlink building service we provide to clients across Kent and beyond.
How to Earn High-Quality Backlinks
Create Content Worth Linking To
The most reliable long-term strategy is also the most straightforward: produce content that other sites naturally want to reference. This includes:
Original research and surveys — proprietary data is highly citable
In-depth guides and how-to articles — comprehensive resources that others reference when explaining a topic
Infographics and visual assets — shareable and easily embedded
Expert opinion pieces — commentary on industry trends that journalists and bloggers quote
Case studies — real-world results that demonstrate credibility and expertise
If your content marketing is consistently useful and original, backlinks become an organic by-product of doing good work.
Digital PR
Digital PR involves pitching stories, data, and expert commentary to journalists and publications in your industry. When a journalist quotes you or features your research, you earn a backlink from an authoritative news or media site — often with significant domain authority.
Tactics include:
Responding to journalist enquiries (tools like Qwoted and Featured can help)
Distributing press releases around genuinely newsworthy announcements
Publishing original data that reporters will cite
Providing expert commentary on breaking industry news
Guest Blogging
Identify high-quality publications in your industry that accept contributed articles. Write genuinely useful content for their audience — not thinly veiled advertisements — and earn a backlink in return. Focus on relevance and quality rather than volume.
Broken Link Building
Use SEO tools to identify pages on relevant websites that link to content that no longer exists. Create a piece of content that could serve as a worthy replacement, then reach out to the webmaster with a helpful suggestion. It’s a win-win: they fix a broken link, you earn a backlink.
Partnerships and Supplier Relationships
Look within your existing business network. Suppliers, partners, industry associations, and even clients may be willing to feature your business on their website. These links are often underutilised despite being relatively easy to secure.
How to Audit Your Backlink Profile
Even if you’re not actively building links right now, it’s worth understanding what your current backlink profile looks like. Here’s a simple audit process:
Step 1: Gather Your Backlink Data
Use an SEO tool to pull a full list of sites currently linking to your domain. This gives you a clear picture of who’s vouching for you, the quality of those sites, and whether any links have been lost recently.
Step 2: Identify Toxic Links
Low-quality or spammy backlinks — from link farms, irrelevant directories, or sites with unusually high spam scores — can harm your rankings. Look out for:
Links from sites with no clear topic relevance
Domains with very low authority and no organic traffic
Sites that exist purely for link exchange
Unnaturally keyword-stuffed anchor text pointing to your pages
Step 3: Remove or Disavow Harmful Links
If you identify toxic links, you have two options:
Request removal — contact the webmaster of the linking site and ask them to remove the link
Disavow — if removal isn’t possible, submit a disavow file through Google Search Console to tell Google to ignore those links
Step 4: Recover Lost Backlinks
Links get lost over time — pages are deleted, URLs change, or sites go offline. Identify valuable backlinks that are no longer active and investigate whether they can be recovered through a 301 redirect or by reaching out to the linking site.
Pair a healthy backlink profile with solid technical SEO foundations — such as correct redirects, canonical tags, and crawlability — to ensure the link equity you earn is actually flowing where it should.
Backlinks and Local SEO
For businesses serving a specific geographic area, local backlinks carry particular importance. Links from local directories, regional news sites, Chamber of Commerce listings, local event sponsorships, and community organisations all signal geographic relevance to Google — helping your business rank in local searches and Google Maps results.
If you’re a business in Kent, earning backlinks from other Kent-based and South East-focused websites strengthens your local authority significantly. This is something we build into our SEO growth strategies for local and regional clients.
Dental practices and healthcare businesses have their own specific considerations — our dental digital marketing service covers backlink acquisition as part of a broader local SEO strategy tailored to regulated industries.
Common Backlink Mistakes to Avoid
Buying links — Google’s guidelines explicitly prohibit paid links intended to manipulate rankings. Penalties can result in significant ranking drops or manual actions from Google’s spam team.
Participating in link exchanges — “I’ll link to you if you link to me” schemes are considered manipulative and carry risk.
Prioritising quantity over quality — one link from a reputable industry publication is worth far more than a hundred links from irrelevant, low-authority sites.
Ignoring anchor text diversity — having the same keyword-rich anchor text on every backlink looks unnatural. A healthy profile includes branded, generic, and keyword-rich variations.
Neglecting link maintenance — backlinks are lost regularly. Not tracking and recovering them means leaving ranking value on the table.
Frequently Asked Questions
What are backlinks in SEO?
Backlinks are hyperlinks from one website to another. In SEO, they act as votes of confidence — when reputable sites link to your content, it signals to Google that your page is credible and worth ranking higher in search results.
How many backlinks do I need to rank on Google?
There’s no magic number. Quality, relevance, and authority matter far more than quantity. A handful of links from genuinely trusted, relevant sites will outperform hundreds of links from low-quality or unrelated sources. The right number depends entirely on your industry, your competitors, and the keywords you’re targeting.
What’s the difference between dofollow and nofollow backlinks?
Dofollow links pass link equity (ranking value) from the linking site to yours. Nofollow links include a tag instructing search engines not to pass this value. Both types can drive traffic and build brand awareness, but dofollow links have a more direct impact on your search rankings.
Are backlinks still important in 2025?
Yes — backlinks remain one of Google’s most significant ranking signals. Whilst the algorithm has evolved considerably, the fundamental principle that trusted, authoritative sites linking to your content validates its quality has not changed. High-quality backlink building continues to be one of the highest-ROI SEO activities available.
How do I know if a backlink is high quality?
Look at the linking site’s relevance to your industry, its domain authority, where the link is placed on the page (body content is best), and the anchor text used. Links from genuinely respected publications in your niche, placed contextually within relevant content, are the most valuable.
Can bad backlinks hurt my website?
Yes. Links from spammy, irrelevant, or manipulative sources — known as toxic backlinks — can harm your rankings. It’s important to audit your backlink profile periodically and either request removal of harmful links or disavow them through Google Search Console.
How long does it take for backlinks to affect rankings?
It varies. Some backlinks are discovered and processed by Google within days; others take weeks or months to influence rankings. The impact also depends on the authority of the linking site and the competitiveness of your target keywords. Generally, backlink building is a medium-to-long-term strategy rather than a quick fix.
Is it possible to do backlink building myself?
Yes, though it requires time, relationships, and consistent content creation. Many businesses choose to work with an SEO specialist to accelerate the process, particularly when targeting competitive keywords. Our backlink building service handles outreach, content creation, and link acquisition on your behalf.
Conclusion
Backlinks are one of the most powerful tools in your SEO arsenal — but only when they’re earned the right way. A single high-quality link from a trusted, relevant source carries more weight than dozens of low-quality ones, and a thoughtfully built backlink profile compounds in value over months and years.
The businesses that win in organic search aren’t the ones who cut corners with link schemes. They’re the ones who invest in creating genuinely useful content, build real relationships in their industry, and take a strategic, long-term approach to authority building.
