When ChatGPT, Perplexity, Google’s AI Overviews, and similar answer engines started intercepting search queries that used to land on traditional results pages, a widely held assumption took hold inside business operations circles: SEO was dying, link building was finished, and budgets pointed at organic search would need to be redirected elsewhere.
That assumption turned out to be wrong. In fact, the opposite has happened. Demand for high-quality link building has increased significantly since AI search engines became mainstream, and the businesses that figured this out early are quietly building competitive moats their slower competitors haven’t yet noticed.
For operations leaders making budget decisions about marketing investment, this matters. Cutting link building spend because “AI killed SEO” is one of the most expensive miscalculations a business can make right now. Here’s why the conventional wisdom got it backwards, what the data actually shows, and what operations teams should be doing about it. This is where link building marketplaces like Serpbays come into the picture. Serpbays connects advertisers directly to the publishers with no additional margin.
The counterintuitive truth about AI search and backlinks
The intuition that AI search would reduce the importance of backlinks made surface-level sense. If users get their answers directly from ChatGPT or Google’s AI Overviews without clicking through to websites, why would link-based authority still matter?
The answer lies in how AI search engines actually work. Large language models don’t generate answers from nowhere — they generate answers by synthesizing information from sources they’ve been trained on or can retrieve in real time. The question those engines have to answer constantly is which sources to trust, which to cite, and which to ignore entirely.
The mechanism AI engines use to make that decision turns out to be remarkably similar to what traditional search engines have always done: they rely on signals of authority and credibility, and backlinks remain one of the strongest signals available.
Recent industry studies bear this out clearly. Analyses of AI Overview citations show that 76% of pages cited in AI-generated answers also rank in the traditional top 10 search results for the same query. The pages AI engines trust most are the same pages that have earned authority through backlinks over time. Separate research analyzing thousands of domains found that sites with stronger backlink authority appear in AI-generated answers significantly more often than sites with weaker authority profiles. Brand mentions across credible sources, particularly in trusted publications, increasingly determine whether a brand surfaces in AI responses at all.
The practical implication is straightforward: businesses that invested seriously in link building over the past several years now benefit twice — they rank well in traditional search results, and they get cited in AI-generated answers. Businesses that didn’t are invisible in both.
Why operations leaders should care about this specifically
Marketing teams understand the SEO mechanics. Operations leaders care about something different: the economics, the budget implications, and the competitive risk.
Three things make this shift specifically relevant to operations decisions:
The cost of paid acquisition keeps rising. Customer acquisition costs across paid channels have been climbing for years, and the trend isn’t slowing. Operations leaders managing marketing P&Ls increasingly find that the channels their finance team understands best — Google Ads, Meta, LinkedIn — deliver less ROI per pound or dollar spent than they did even a few years ago. Organic search has become more important precisely because paid acquisition has become more expensive, and link building is what keeps organic search competitive.
AI search compounds the competitive moats of established players. Because AI engines disproportionately cite authoritative sources, the businesses already cited by AI today will continue being cited tomorrow. New entrants face a higher hill to climb than they did a few years ago — not just to rank in Google, but to earn the citations in AI engines that increasingly drive discovery. For operations leaders thinking about competitive positioning over the next three to five years, the cost of falling behind on link building has gone up, not down.
The execution model has changed in favour of operationally-minded buyers. Traditional link building was operationally messy: agencies on long-term retainers, opaque pricing, weak attribution between spend and outcome. The modern toolkit looks completely different. Direct-to-publisher marketplaces let operations teams treat link acquisition the way they’d treat any other supplier relationship — clear unit economics, transparent inventory, predictable outputs. Platforms like Serpbays, which gives businesses direct access to 10,000+ verified publishers globally without middleman markup, let operations leaders build link budgets the same way they’d build any other operational budget: with line items, attribution, and clear cost-per-unit metrics.
This shift matters operationally. The reason link building was historically frustrating for ops leaders wasn’t that it didn’t work — it was that the procurement model was opaque. That problem has largely been solved by modern marketplaces, which makes link building easier to budget for, easier to scale up or down, and easier to defend in finance conversations.
What the modern link building stack actually looks like
For operations leaders trying to understand what they should be funding, the modern link building stack has three layers worth knowing.
The first layer is content production. Every backlink earned through guest contributions, digital PR, or publisher partnerships requires content the publisher will actually accept and publish. This is where most in-house link building programmes quietly collapse — not because the link acquisition strategy is wrong, but because no one on the team has bandwidth to write the 1,500-word articles that publishers expect.
The economics of solving this in-house rarely work for mid-sized businesses. A skilled content writer covering business and B2B topics costs £60,000-£90,000 per year in salary alone in most UK markets, plus benefits, tools, and management overhead. Equivalent output through specialist content agencies — providers like Wordscloud, which works with businesses globally producing search-optimised content at scale through vetted writer networks — typically runs at 50-70% lower total cost when measured fully loaded, with no recruitment risk and no productivity ramp time. For operations leaders thinking about build-versus-buy, the content production layer is almost always a buy decision once the volume exceeds three or four pieces per month.
The second layer is link acquisition itself. This is where the marketplace shift matters most. Traditional managed link building agencies typically charge £3,000-£15,000 per month on retainer, with opaque relationships between spend and outputs. Modern marketplaces like Serpbays operate on a transparent pay-per-link model with no retainer commitment, letting operations teams scale link budgets up during growth periods and down during cash conservation periods. The 12-month link guarantee built into the platform also addresses what was historically the biggest unmeasured cost in link building: link rot, where placements purchased through cheaper providers disappeared within months and quietly destroyed ROI on the original spend.
The third layer is measurement. Operations leaders should insist on attribution between link spend and ranking outcomes — not as a vanity metric, but as a basic accountability mechanism. Free tools like Google Search Console show exactly which pages are ranking and which keywords are improving over time. Pairing that with referring domain tracking (the count of unique websites linking to your business, available through any major SEO platform) gives operations teams the input-output relationship they need to defend the spend in budget reviews.
The strategic question operations leaders should be asking
For most businesses, the question isn’t whether to fund link building post-AI. The data is clear that authority signals are getting more valuable, not less, and the businesses that retreat from link building investment are the ones AI engines will increasingly ignore.
The real question is whether the current execution model fits the operational realities of the business. For businesses still working with traditional retainer-based agencies, the modern combination — outsourced content production through specialist agencies, marketplace-based link acquisition with no retainer commitment, and in-house strategy and measurement — typically delivers comparable or better results at significantly lower cost. For businesses doing link building in-house with limited capacity, modern marketplaces remove most of the operational complexity that historically prevented programmes from scaling.
The businesses winning competitive search categories today aren’t doing anything mysterious. They’re running the same basic playbook their competitors are running, but with better discipline around execution and better understanding of how the modern toolkit lets them scale link building without committing to operationally inflexible agency relationships.
What ops leaders should do this quarter
For operations leaders reading this and wondering what action makes sense in the next ninety days, three steps:
First, audit your current marketing spend by channel and ask honestly: what percentage is going to channels that compound (organic search, link building, content) versus channels that disappear the moment you pause them (paid ads, sponsored social)? If the ratio is heavily skewed toward channels that stop working when spending stops, you’re likely overpaying for customer acquisition.
Second, if you have a link building programme running, audit its economics. What’s the all-in cost per quality referring domain acquired? How does that compare to what modern marketplaces offer? Many businesses discover they’re paying two or three times the market rate for link acquisition through legacy agency relationships, simply because nobody recently challenged the model.
Third, if you don’t have a link building programme, start one — even at modest scale. A starter programme acquiring three to five quality backlinks per month through a marketplace, supported by four to eight pieces of content monthly through a specialist content agency, costs most businesses between £1,000 and £3,000 monthly. That investment, sustained for twelve to eighteen months, typically delivers organic traffic growth that exceeds what an equivalent paid advertising budget would produce — and the returns continue compounding after the spending levels off.
The businesses that figure this out earlier tend to be the ones that build durable competitive positions in their categories. The AI search era hasn’t reduced the importance of link building. It has quietly elevated it, while also making the execution model significantly more accessible to operations leaders who treat marketing as a business function rather than a creative one. The window for catching up is open now. It won’t stay that way indefinitely.
