Search has changed more in the past two years than in the decade before it. Results pages now mix classic blue links with AI-generated overviews, and a growing share of people ask chatbots and AI assistants for recommendations before they ever click through to a website. For agencies that manage SEO for clients, that shift raises a practical question: does link building still matter, and if so, what kind?
The short answer is that links still matter, but the way agencies choose and buy them is getting more deliberate. Instead of treating every backlink as roughly the same, the agencies doing this well are matching each placement to a specific goal, a specific page and a specific audience.
From Link Volume to Link Purpose
For years, many SEO campaigns were measured by how many links were built in a month. That approach has faded. Search engines have become much better at judging the context of a link, and clients have become more demanding about what they are paying for.
A recent guide from Vazoola, a link building company founded in 2010, puts it simply: the format matters, but the purpose comes first. The guide argues that a cheaper placement can outperform an expensive one if the page and its readers fit the client’s goals better, and that agencies should decide what a link is supposed to achieve before they decide where to buy it.
That idea sounds obvious, but it changes how campaigns are planned. A link meant to help a product page rank is a different purchase from a link meant to send referral traffic, and both differ from a placement designed to build brand recognition.
The Link Types Agencies Rely On
Most agency link building now draws on a familiar set of formats, each with its own strengths.
Guest posts remain the most controllable option. The agency can shape the topic, the context around the link and where it appears in the article. Niche edits, where a link is added to an existing article, can be quicker and cheaper, though the quality of that particular page matters a great deal. A well-maintained resource that still gets traffic is a very different home for a link than an old post nobody reads.
Sponsored content and paid placements are valuable for reach and referral traffic, and they are clearly labeled as paid. Digital PR, built around research, data or a strong story, can earn coverage on major publications, although results are less predictable because editors decide what they run.
Two other formats are growing quickly. White-label link building lets agencies hand off prospecting, outreach and content production while keeping the strategy and the client relationship in-house. Brand mention placements focus on getting a client’s name into relevant articles, with or without a link.
Why Brand Mentions Matter More Now
That last category is where AI search comes in. Large language models learn about brands from the text they are trained on and the pages they retrieve. When a company is mentioned consistently in relevant, credible content, it is more likely to appear when someone asks an AI assistant for recommendations in that space.
This has pushed many agencies to track not just how many links a client earns, but also how often and in what context the brand is mentioned. The words around a mention matter. A brand described as a trusted option for a specific need sends a clearer signal than a passing reference in a long list.
For tech companies in particular, this is becoming part of standard visibility planning. A software brand that wants to show up in AI-generated comparisons needs a presence in the articles, reviews and guides those systems draw on.
Building a Smarter Link Strategy
The agencies seeing the best results tend to follow a clear process. They start by defining what the client needs most, whether that is rankings for a few commercial pages, more referral traffic or broader brand awareness. They then identify the pages that need support and review the existing link profile to see where the gaps are.
Budget comes next. Rather than spreading money across as many placements as possible, they match the quality of each link to what the client can invest and how competitive the industry is. A local service business and a national software company need very different plans.
Finally, they decide how success will be measured before the campaign begins. That might mean keyword movement, referral sessions, brand search volume or mentions in AI answers. Agreeing on this early makes reporting more honest and keeps the client relationship on firm footing.
Trust Between Agencies and Clients
Transparency is a recurring theme across the marketing industry. Organizations such as the Association of National Advertisers have long focused on how brands and their agencies work together, and clients increasingly expect to understand what they are buying and why.
For link building, that means explaining the role of each placement, labeling paid links properly and avoiding promises about rankings that no one can guarantee. Agencies that are open about their methods tend to keep clients longer.
What Comes Next
AI search is still evolving, and no one knows exactly how much weight future systems will give to links versus mentions. What seems clear is that quality, relevance and context will keep rising in importance. For agencies, the winning approach in 2026 is less about chasing volume and more about building a body of credible references that help clients get found, wherever their audience is searching.
