Backlink Building: What Moves Rankings

Creating backlinks means earning links from other websites that point to yours, and those links remain one of the strongest signals Google uses to assess whether a page deserves to rank. The mechanics are straightforward: another site links to your content, Google follows that link, and some portion of that site’s authority transfers to yours. The difficulty is not understanding what backlinks are. It is building them in a way that compounds over time rather than creating short-term noise that fades or, worse, triggers a penalty.

This article is part of a broader series on building search visibility from the ground up. If you want the full picture, the Complete SEO Strategy hub covers everything from technical foundations to competitive positioning in one place.

Why Most Backlink Advice Misses the Point

When I was running an agency, we had clients who would come in with a list of competitor backlinks pulled from a tool and a simple request: get me those same links. It sounds logical. If your competitor has a link from a particular publication and they outrank you, getting that same link should help close the gap.

Sometimes it did. Often it did not. The reason is that backlinks are a proxy for something more fundamental: the perceived credibility and relevance of your content in the eyes of people who are already trusted by Google. When you reverse-engineer a competitor’s link profile without asking why those sites linked to them in the first place, you are chasing the symptom rather than the cause.

The SEMrush overview of what backlinks are and how they work explains the mechanics clearly enough. But mechanics are not strategy. You can understand how a link passes authority and still build a link profile that does almost nothing for your rankings, because the links are irrelevant, low-quality, or concentrated in ways that look manipulative.

The businesses that build strong link profiles consistently are the ones that treat link acquisition as a byproduct of creating something genuinely useful, then actively distributing it to the right audiences. The outreach is secondary. The asset is primary.

What Makes a Backlink Worth Having

Not all backlinks contribute equally to your rankings, and some can actively harm them. Before building anything, it is worth being clear on what you are actually trying to acquire.

The factors that determine a backlink’s value are well-established at this point. Domain authority matters, but topical relevance matters just as much. A link from a mid-authority site that operates in your exact niche will typically outperform a link from a high-authority general news site with no topical connection to your content. Google is increasingly good at understanding what a page is about, and a link from a contextually aligned source carries more weight as a relevance signal.

The placement of the link within the page also matters. A link embedded naturally in editorial body copy is more valuable than a link in a sidebar, footer, or author bio. Google’s systems are sophisticated enough to distinguish between a genuine editorial endorsement and a link that was placed because someone paid for it or asked nicely.

Anchor text is another variable that is frequently mishandled. The instinct is to use exact-match keywords in every anchor, but that approach has backfired on businesses for years. The Search Engine Journal’s analysis of over-optimised anchor text explains why uniform exact-match anchors look unnatural and can suppress rather than lift rankings. A healthy profile has a mix: branded anchors, partial matches, generic phrases like “this article” or “read more,” and some exact-match anchors where they occur organically.

Finally, the linking page itself needs to be indexed and crawlable. A link from a page that Google cannot access, or has been told to ignore via a noindex tag, passes nothing. This sounds obvious but it catches people out regularly, particularly when they are building links through content partnerships where they have no visibility into the technical health of the host site.

The Asset-First Approach to Link Building

The most reliable way to build backlinks at scale is to create content that people in your industry want to reference. This is sometimes called “linkable asset” creation, and it is the approach I have seen work consistently across industries, from B2B technology to retail to financial services.

Linkable assets share a few characteristics. They contain information that is difficult to find elsewhere, or they present existing information in a more useful or accessible format. They are specific enough to be credible and broad enough to be relevant to a wide range of writers and publishers in the space. And they are built to last, not tied to a news cycle or a short-term campaign.

The formats that generate links most reliably tend to be original research and data, comprehensive reference guides, free tools or calculators, and well-structured comparison or benchmark content. Visual formats like detailed infographics can work in some industries, though their effectiveness has declined as content production has become cheaper and more widespread.

One of the more effective things we did at agency level was commission small-scale original research, typically surveys of a few hundred people in a relevant audience, and publish the findings as standalone reports. The upfront cost was modest. The link acquisition over the following 12 to 18 months was significant, because journalists and bloggers in the space needed data to cite and we were one of the few sources providing it. That is the logic: if you want links, become a source.

The SEMrush guide to getting backlinks covers a range of asset-based and outreach-based approaches. What it reinforces is that the tactics with the longest shelf life are the ones where the asset does most of the work.

Outreach That Does Not Waste Everyone’s Time

Even the best linkable asset needs distribution. Creating something and waiting for links to arrive organically is a strategy that works eventually for exceptional content, but most businesses cannot afford to wait. Outreach accelerates the process.

The problem with most link outreach is that it is lazy. Generic templates sent to hundreds of contacts, with no personalisation and no clear reason why the recipient would benefit from linking to your content. I have been on the receiving end of this kind of outreach throughout my career, and it goes straight to the bin. Not because I am precious about it, but because there is no reason to act on it.

Effective outreach starts with a tight, well-researched target list. You are looking for pages that already link to similar content, writers who cover your topic regularly, and publications where your asset would fill a genuine gap. The pitch needs to be specific: why this asset, why for this audience, why now. One sentence of genuine personalisation will outperform three paragraphs of template copy every time.

The follow-up matters too. A single email rarely converts. Two or three well-timed follow-ups, spaced over a couple of weeks, will roughly double your response rate without being aggressive. The tone throughout should be collegial, not salesy. You are offering something useful to someone who covers your space, not asking for a favour.

When I was scaling the agency’s SEO practice, we built a simple qualification framework for outreach targets: domain relevance, content activity in the past 90 days, and whether the site had linked to similar content before. If a site met all three, it went on the list. If it met one or none, it did not. That filter alone cut our outreach volume by about half and improved our conversion rate significantly. More targeted is almost always more effective than more volume.

Broken Link Building and Resource Page Tactics

Two tactics that have maintained their effectiveness over years of algorithm changes are broken link building and resource page outreach. Both work because they frame your request in terms of value to the recipient rather than value to you.

Broken link building involves finding pages in your niche that link to content that no longer exists, creating a replacement for that content, and then notifying the site owner. They have an incentive to fix the broken link because broken links are a user experience problem and a minor technical issue. You are offering a solution, not asking for a favour. The conversion rates on well-executed broken link campaigns are meaningfully higher than cold outreach for new placements.

The process requires a tool that can identify broken links at scale. Ahrefs, SEMrush, and Screaming Frog all have this functionality. You identify a dead page that was linked to from multiple sites, create something better or equivalent, and reach out to each linking domain. The pitch is simple: you noticed they have a broken link, you have created something that covers the same ground, and you thought it might be useful as a replacement.

Resource page outreach follows a similar logic. Many sites in every industry maintain curated lists of useful tools, guides, or references for their audience. If you have created something that belongs on one of those lists, reaching out to the curator is a reasonable and low-friction request. what matters is that your asset genuinely belongs there. Pitching a thinly produced blog post for inclusion on a high-quality resource page is a waste of everyone’s time.

Digital PR as a Scalable Link Acquisition Channel

Digital PR sits at the intersection of traditional public relations and SEO, and when it is executed well it is one of the most efficient ways to build high-authority links at scale. The premise is simple: create stories, data, or commentary that journalists and editors want to publish, and earn links from the coverage.

The challenge is that most content marketed as digital PR is not actually newsworthy. It is a thinly veiled product announcement or a piece of research that answers a question nobody was asking. Journalists receive hundreds of pitches a week. The ones that cut through are the ones that are genuinely surprising, timely, or specific to an audience the journalist serves.

The formats that work best for digital PR link acquisition are data-led stories tied to a current trend, reactive commentary from a credible spokesperson, and original research that challenges a widely held assumption. The last category is particularly effective because it gives journalists a reason to write something that is not just a repackage of existing coverage.

I judged the Effie Awards for several years, and one of the consistent patterns in campaigns that won was that they had a clear, defensible claim at their centre. Something specific enough to be interesting and broad enough to be relevant. That same discipline applies to digital PR for link building. Vague claims get ignored. Specific, well-supported claims get coverage.

The Ahrefs webinar on backlinks and brand mentions in 2025 covers how digital PR and unlinked brand mentions factor into modern link building strategy, and it is worth reviewing if you are building out a programme from scratch.

Guest Posting: Still Useful, Often Misused

Guest posting has been declared dead at least a dozen times over the past decade, and it keeps coming back. The reason is that it works when it is done properly. The problem is that it is rarely done properly.

The version of guest posting that does not work is writing generic, low-effort content for any site that will accept it, with an exact-match keyword anchor buried in the author bio. Google has been explicitly clear that links in guest posts intended primarily for link building are considered manipulative. That does not mean guest posts cannot produce legitimate links. It means the guest post needs to be genuinely good, placed on a relevant and authoritative site, and linked in a way that serves the reader rather than the algorithm.

The version that does work is writing substantive, original content for publications your target audience actually reads. The link is a byproduct of the relationship and the content quality, not the primary objective. When I think about the guest contributions that produced lasting value for the agencies I ran, they were the ones where we pitched a specific idea to a specific editor because we had something genuinely useful to say to their audience. The link was almost incidental.

If you are evaluating a guest posting opportunity, ask three questions. Does this publication have a real, engaged audience in my space? Would this content be published on its own merits, without the link? Is the link placement natural and editorially appropriate? If the answer to any of these is no, the placement is probably not worth pursuing.

The Crazy Egg overview of backlink types and tactics has a useful breakdown of where guest posting fits relative to other link acquisition methods, including the risk profile of different approaches.

Building Links Through Partnerships and Supplier Relationships

One of the most underused sources of legitimate backlinks is the network of business relationships most companies already have. Suppliers, partners, industry associations, trade bodies, and clients all represent potential linking opportunities, and they are far easier to convert than cold outreach because the relationship already exists.

Many companies have supplier or partner pages on their websites. If you are listed on those pages without a link, asking for one is a completely reasonable request. Industry associations and trade bodies often maintain member directories or resource pages. If you are a member and not linked, you are leaving something on the table.

The same logic applies to case studies and testimonials. If a client features your work in a case study on their site, or if you provide a testimonial for a supplier, those are natural opportunities for a link back to your site. Most businesses do not think to ask, and most suppliers and clients will say yes if asked directly.

These links will not move mountains on their own, but they contribute to a diverse and natural-looking link profile, and they come from sites with a genuine connection to your business. That combination of relevance and authenticity is exactly what a well-rounded link profile should contain.

The Role of Internal Links in Supporting Your Backlink Strategy

This is often overlooked in link building discussions, but internal linking plays a direct role in how effectively your backlinks translate into ranking improvements. When an external link points to a page, the authority it passes can be distributed further through your site via internal links. If your most-linked pages are not internally connected to the pages you actually want to rank, you are leaving distribution gains on the table.

The practical implication is that your linkable assets should not sit in isolation. They should be connected to your key commercial pages through well-structured internal links, so that the authority earned by your content assets flows toward the pages that drive business outcomes. This is one of the things that separates a mature SEO programme from a collection of disconnected tactics.

When I was managing large-scale SEO programmes across multiple client accounts, the sites that compounded their gains most effectively were the ones where link acquisition and internal architecture were treated as connected disciplines. Earning a link to a resource page and then connecting that resource page to your product or service pages with clear, relevant anchor text is a simple but consistently effective pattern.

Monitoring Your Link Profile and Avoiding Common Mistakes

Building backlinks is only part of the work. Monitoring what you have and managing the quality of your profile over time is equally important. Link profiles degrade naturally as sites shut down, pages get removed, and previously strong domains decline in authority. Regular audits keep you aware of what is working and what needs attention.

The two most common mistakes I see in link profile management are ignoring toxic links and obsessing over toxic links. Both cause problems. Ignoring a pattern of spammy, irrelevant links pointing to your site, particularly if they arrived in a short burst, can leave a penalty risk unaddressed. But disavowing links aggressively and unnecessarily can remove signals that were contributing positively to your rankings. Google’s guidance on disavow has consistently been to use it as a last resort, not a first response.

The Moz analysis of failed SEO tests includes useful case studies on interventions that backfired, including overly aggressive link management. It is a useful reminder that the instinct to act is not always the right one.

The other monitoring priority is tracking which of your link-building activities are producing results. Not just link counts, but ranking movements and traffic changes on the pages receiving links. This is where a lot of SEO programmes lose discipline. They measure outputs, such as links built, rather than outcomes, such as ranking improvements and organic traffic. Those are different things, and conflating them leads to programmes that look active but do not produce business results.

If you want to see how link building fits into a broader search strategy, the Complete SEO Strategy hub connects all of these disciplines, from technical SEO and on-page optimisation to content strategy and competitive analysis, in a way that makes the interdependencies clear.
