How Agencies Build High-Quality Backlinks: Proven Strategies to Deliver SEO Results for Clients
If you’re an agency owner or consultant, chances are one (or both) of these scenarios sounds familiar:
A client asked, “Do you also offer SEO backlink building?”, and you didn’t have a clear answer.
You’ve already heard or read about what SEO backlinks can do for rankings and visbility, and are considering adding it to your services to help clients grow faster.
Either way, you have this one question in mind: How do agencies build high-quality backlinks for their clients in a way that's effective, easy to execute, and worth the time?
Ahead, I’ll walk you through link-building strategies that SEO agencies use today to earn real, editorial backlinks (including the exact frameworks we run at RepuLinks) so you can apply them yourself and deliver stronger results without reinventing the wheel.
Expert Sourcing Platforms (HARO, Featured, Qwoted)
Expert sourcing platforms like HARO, Featured, and Qwoted can earn you editorial backlinks in exchange for an expert response or quote.
Journalists from all over the world use these platforms to find experts and gather insights for the pieces they’re writing. You simply respond to a query, and if your quote hits the bullseye, you earn a high-quality backlink to your site.
Of course, there are nuances between platforms, but that’s generally how it works. Very simple and very accessible (HARO, for example, is 100% free).
In fact, using this linkbuilding strategy, Repulinks has placed many clients in big publications like Forbes, Yahoo Finance, and Business Insider, among other high-authority, high-DR niche websites.
Not only did these placements increase Google rankings and domain authority. They also led to more branded mentions inside AI search results (from LLMs like Gemini and ChatGPT) and put them in front of far more qualified prospects.
Now, you might wonder, "For something so simple, what's the catch?"
The simplicity, while its biggest strength, is also its biggest weakness. Since the barrier to entry is so low, virtually anyone can submit a quote – and that includes spammers, posers, and those who just copy-paste generic AI responses.
Competition is so intense that, at this point, it has become a numbers game. You’ll need to respond consistently and strategically to increase your chances of getting selected.
Proactive Digital PR
Proactive digital PR is the process of creating newsworthy stories, insights, or data and pitching them directly to online publications to earn editorial backlinks.
Unlike expert sourcing platforms, where you’re in a more reactive position waiting for journalists to request quotes, here you initiate the conversation. It’s akin to traditional public relations – just adapted to the online world – in the sense that you decide:
What narrative you want associated with your client
What trends or conversations you want to enter
What positioning angle strengthens authority
What data or commentary makes the pitch compelling
That’s to say, with proactive digital PR, you have far more control. And when executed well, a single campaign can secure multiple high-quality editorial backlinks across different publications.
But with greater control also comes a price.
Proactive digital PR is heavier operationally and involves more moving parts. It requires time for research and angle validation, creative ideation to avoid sounding overly promotional, careful media list building, personalized outreach, and coordination between strategists, writers, and outreach specialists.
And because you’re creating the angle from scratch, there’s no guarantee journalists are actively looking for that story. If the angle doesn’t resonate, the campaign may not land, no matter how much effort went into it.
Reclaiming Unlinked Brand Mentions
Reclaiming unlinked brand mentions is the process of finding places online where your brand, product, founder, or website is mentioned but not linked – and then asking the publisher to turn that mention into a clickable backlink.
You're not pitching from scratch anymore. Instead, you use an SEO tool like Ahrefs, SEMrush, or even Google Alerts to monitor and notify you of new brand mentions. From there, you simply reach out to the webmaster and request that they link to the source they’ve already referenced.
This approach is arguably one of the quicker, lower-effort strategies for earning high-quality links. But of course, it’s not without its drawbacks – primarily that success depends entirely on existing visibility.
If your brand isn’t being mentioned organically yet, there’s very little (or even nothing) to reclaim. This is common for newer websites or lesser-known businesses.
Regardless, the number of reclaimable mentions at any given time is limited. Once you’ve exhausted what’s available, you’ll have to wait for new mentions to surface.
And for that reason, this cannot serve as your sole link-building strategy. Instead, it works best as a complementary tactic that quietly converts existing awareness into SEO authority.
Podcast & Interview Guesting
Podcast and interview guesting builds high-quality backlinks by placing your client directly in front of an audience as the guest speaker or expert – and then earning contextual links from the episode’s:
Show notes
Media pages
Embedded players
Transcripts
Episode descriptions
The even better news? Links aren’t limited to those placements.
In many cases, journalists and creators pull direct quotes from a podcast interview to enrich the pieces they’re writing. If your client’s insight happens to be the one that stands out, the greater the chances of their name or company getting mentioned, creating an entirely new backlink opportunity.
On top of that, many agencies use podcast guesting as a way to diversify a backlink profile.
For context, search engines favor a natural-looking link profile, one that isn’t concentrated on just blog posts or one type of website.
Podcast and interview guesting helps achieve that diversification. You can earn links from video platforms like YouTube, streaming platforms like Spotify, publisher websites hosting transcripts – even email newsletters and curated media roundups, if your client already has a strong reputation as an industry expert.
The drawback? Naturally, it’s time-intensive.
Booking quality appearances requires outreach, relationship-building, and preparation.
More importantly, you can’t delegate the voice of the brand. An actual expert has to show up, articulate ideas clearly, communicate value, and represent the company well.
Otherwise, while you might still secure a backlink (which is the bare minimum from an SEO perspective), you lose the compounding benefit of authority, trust, and relationship-building that makes this strategy powerful in the first place.
Resource Page & Directory Placements
Resource page and directory placements involve getting a business listed on curated pages that compile helpful tools, services, or organizations within a specific niche or location.
Think of websites like Clutch, Yelp, the Better Business Bureau, and Angi, among many others.
As an agency owner yourself, you’ve likely signed your own business up on relevant directories or industry listings. When that listing went live with your website URL included, you got a backlink pointing to your site.
You can use the same process to secure these kinds of backlinks for your clients.
One thing to keep in mind when doing this: always focus on high-quality, contextual sites. By contextual, I mean pages that are genuinely relevant to the industry or location, and that exist to provide real value to users.
Take, for instance, a curated “Top Marketing Agencies in Texas” page. That carries far more contextual weight for a Texas-based agency than some random global link directory stuffed with thousands of unrelated listings.
Of course, no one’s stopping you from signing up for generic directories or large business listing sites. But doing this at scale, especially with the intention of manipulating rankings, can violate Google’s guidelines.
Search engines are more than capable of detecting unnatural directory patterns. So think twice about cutting corners. Better yet, don’t even think about it.
Broken Link Building
Broken link building earns high-quality backlinks by replacing dead resources on authoritative websites with relevant, working content from your client.
Here's the rub: editors and webmasters do not want their visitors landing on 404 pages. Broken links create poor user experience and weaken the credibility of their content.
When you identify a dead resource and approach them with a legitimate substitute, you’re solving a problem for them, and in return, you earn a backlink.
The real work, first and foremost, is finding relevant industry websites that have broken outbound links. To do this effectively, you’ll need tools like Ahrefs, Screaming Frog, or sometimes even manual crawling of resource pages.
So, you’re essentially auditing other people’s content for opportunities where something valuable once existed, but no longer does.
The second thing? You must absolutely have better, superior content than the original resource. For example, if the original resource had outdated statistics, yours should contain current data. If the previous content lacked visuals or structure, yours should improve on that.
Because otherwise, why would they replace the link?
If you can’t offer something stronger, or at the very least comparable in value, the broken link stays broken, and you walk away having essentially done free audit work for nothing.
Guest Posting Campaigns
Guest posting is the practice of writing and publishing an article on another website within your industry, with the agreement that you receive a backlink to your client’s website within the content or author bio.
To execute this well, you need several things:
Strong prospecting: Not all websites are worth writing for. You’ll need to assess domain quality, traffic, relevance, and overall content standards.
Strong pitch: This is where many campaigns fail. Editors receive hundreds of generic guest post emails. If your pitch feels templated, self-promotional, or disconnected from their audience, it gets ignored.
Quality content: Even if a pitch gets accepted, poor writing (particularly generic AI copy) can damage relationships and close future doors.
Strategic cost–benefit judgment: Ask yourself: is jumping through strict editorial hoops, competing with dozens of contributors, and spending weeks creating content really worth it? If the return is just a marginal link, the juice may not be worth the squeeze.
Guest posting is one of the oldest and most widely used link-building strategies. However, an uncomfortable reality surrounding the practice is that many sites openly accepting guest posts are not truly editorial platforms, but rather link vendors who ask for huge dollars “under the table” per backlink – a clear violation of search engine guidelines.
So vet carefully as not every “guest post opportunity” is what it claims to be.
Custom Linkable Asset Creation
Custom linkable asset creation is how you attract backlinks instead of constantly chasing them.
This strategy involves building assets that publishers and content creators genuinely want to reference because it enhances the quality of their own content. Common examples include:
Original research
Data studies
Tools (e.g. calculators) and infographics
In-depth guides
Industry reports
Today’s leading data-driven B2B agencies (e.g. NP Digital, WebFX) are living proof that this approach is one of the most effective long-term strategies in link building. They’ve become citation hubs within their niche, with statistics pages and reports that get cited almost everywhere.
But those achievements came with careful thought and execution – and you should expect the same level of effort if you want similar results. That includes:
Looking at what’s already earning links in your industry. Use tools like Ahrefs or SEMrush to identify the types of pages competitors are attracting backlinks to.
Choosing the right type of asset. It could be a statistics page, an original survey, a calculator, or a detailed guide, depending on what fits the niche.
Making sure your content is better than what’s already out there. More updated, more comprehensive, and easier to reference.
Promoting it. Reach out to relevant websites, journalists, or partners so people actually see it. A great asset buried on your site won’t magically earn links.
Being ready to invest time and effort. Creating strong assets takes research and production work.
As you can see, building high-quality linkable assets isn't lightweight work. But when done effectively, it compounds and can continue generating backlinks for months, and even years, long after the initial campaign ends.
White-Label Link Building
White-label link building outsources backlink acquisition to another agency specializing in link building, but delivers the results under your own agency’s brand.
Basically, you hire a link-building agency to handle all the dirty work, including:
A full-blown, multi-strategy link-building system aligned with your goals (not just randomly picking one or two tactics we discussed earlier)
Paying for and operating the necessary SEO tools for outreach, analysis, and prospecting (no need to stress about learning all that yourself)
Their own proven system for earning links at scale (no trial and error on your end, and no need to hire and train an in-house team)
What’s really left for you are the easy parts: you take the credit, report the wins to your client, and collect the money.
The icing on the cake? White-label link building gives you the leverage to upsell higher-value packages and increase your monthly revenue by $10,000 or more.
It’s actually an open secret that many agencies choose to white-label this part of SEO. Beyond the obvious upsides, it comes down to the fact that acquiring high-quality links is no easy task. In fact, the latest statistics show that marketers from large companies consider link building one of the most difficult aspects of SEO.
Now, if you’re already killing it, or off to a cracking start landing a handful of backlinks each month using one or a combination of the strategies we discussed, you may not need a white-label partner right now.
But keep performing at that level and growth will catch up fast. More clients, more campaigns, more demand. And that naturally calls for a system that scales without compromising quality or consistency.
If this is something you see happening in the near future, consider, as early as now, looking for a link-building partner that already has proven systems in place.
