There’s a question we’re hearing more and more from marketing leaders right now, and it goes something like this: “We’ve optimised for Google for years. Do we need to start again?”
The short answer is no. But the longer answer is that the rules of visibility are quietly shifting, and the businesses that spot this early will have a meaningful head start.
We’re in the middle of a transition from SEO (Search Engine Optimisation) to AEO: Answer Engine Optimisation. Where SEO was about getting your website to appear in a list of search results, AEO is about becoming the source that AI tools, Klaude, ChatGPT, Perplexity, Google’s AI Overviews, and Copilot actually cite when someone asks a question. That’s a fundamentally different game.
And it raises a genuinely useful question: if you had limited time and resources, which platforms would you invest in first?
At Brandlective, we’ve been working through this question, both for our own presence and for the clients we support. Here’s where we landed, and why.
The Criteria: What Makes a Platform AEO-Relevant?
Before we name the three, it’s worth explaining what we were looking for. Not every platform is created equal when it comes to AI visibility. The platforms that matter most for AEO share a few characteristics:
They’re actively indexed by AI tools. They produce content that looks like peer-validated, authentic opinion, not brand messaging. They generate structured, question-and-answer style content. And they have a track record of appearing inside AI-generated responses.
With that filter applied, three platforms stand out clearly.
Platform 1: Reddit
If this surprises you, you’re not alone. Reddit isn’t where most marketers instinctively think to invest time. It’s messy, it’s niche, and it can be actively hostile to anything that smells like promotion. But here’s the thing: that’s exactly why AI tools love it.
ChatGPT, Perplexity, and Google’s AI Overviews have all been observed to draw heavily on Reddit threads when generating responses, particularly for questions involving opinion, experience, or peer recommendations. The logic makes sense: Reddit threads are written by real people who have actually used products, worked in industries, and formed genuine views. AI models treat that peer-validation as a quality signal.
What this means for your brand is significant. When someone asks an AI tool “what’s the best approach to healthcare marketing?” or “how do purpose-led businesses build trust online?”, the responses served are often based on Reddit content, not blog posts, agency websites, or press coverage.
The opportunity is to be the voice that shows up in those threads. Not through promotional posts, and definitely not through anything that reads like an ad, Reddit users are extraordinarily good at detecting inauthenticity, and the consequences of getting it wrong are severe. The opportunity is through genuine participation: answering questions helpfully, contributing expertise in relevant subreddits, and building a presence that earns trust over time.
This is a long game. Reddit requires patience. New accounts with low karma have their comments automatically filtered or removed, so the first few weeks are about building credibility through participation rather than broadcasting. But the payoff of appearing in AI-generated answers across multiple tools is arguably the highest-return AEO play available right now.
The subreddits that matter depend entirely on your niche. For B2B and marketing professionals, communities like r/marketing, r/entrepreneur, r/digital_marketing, and industry-specific forums are worth identifying and genuinely contributing to. For healthcare businesses, there are highly active communities where real patients and professionals share experience and where authoritative, helpful contributions carry real weight.
Platform 2: LinkedIn
LinkedIn might feel like the obvious choice, so it’s worth explaining why it earns its place here… and it’s not for the reason most people assume.
The common argument for LinkedIn is reach and a professional audience. Both are real. But the AEO argument is more specific: LinkedIn’s long-form content is increasingly being indexed and surfaced by AI tools as they generate responses to professional and B2B queries. Articles published on LinkedIn, and newsletter content in particular, are being treated as authoritative sources in ways that a standard blog post that is sitting on a domain with limited authority often isn’t.
This matters because the format of LinkedIn content, when done well, maps naturally to what AI tools look for. A well-structured LinkedIn article that opens with a clear question, works through the answer with genuine evidence and examples, and closes with a specific takeaway is almost purpose-built for AEO. It’s question-matched, structured, and attached to a professional identity that provides an additional trust signal.
There’s also a compounding dynamic at play. LinkedIn content generates comments, reshares, and reactions — all of which signal engagement and relevance. AI tools aren’t just indexing static text; they’re increasingly sensitive to content that demonstrates real human response. A LinkedIn article that generates genuine discussion carries more weight than one that sits quietly.
For purpose-led businesses and those operating in healthcare, LinkedIn long-form content is where thought leadership turns into AI visibility. The key is writing content that directly answers the questions your audience is already asking, rather than content that exists to promote your services. That distinction sounds simple, but it changes almost everything about how you structure a piece.
The formats that work best for AEO on LinkedIn are: long-form articles (1,000 words or more, structured around a specific question), regular newsletters with a consistent theme, and story-led posts that convey a transferable lesson. The last format is particularly effective because it combines human resonance with the kind of specific, experience-based insight that AI tools treat as high quality.
Platform 3: Google Business Profile
This is the most underestimated of the three, and possibly the highest return for the lowest time investment, particularly for local businesses or any brand with a physical or service-area presence.
Here’s what most businesses miss about Google Business Profile in the context of AEO: Google’s AI Overviews pull heavily from structured, verified business data. When someone searches a service plus location, or asks an AI tool a question that has a local component, the businesses that appear in AI-generated responses are overwhelmingly those with well-maintained, information-rich GBP profiles.
A GBP profile with detailed service descriptions, active Q&A content, regular posts, and well-managed reviews doesn’t just improve traditional local SEO, it feeds directly into the structured data layer that Google’s AI uses to generate answers.
The Q&A section alone is a significantly underused AEO asset. Most businesses leave it empty or allow it to be populated haphazardly by members of the public. The smarter approach is to pre-populate it with the questions your prospects actually ask, written as direct, informative answers rather than sales copy. These answers become prime material for AI-generated responses.
Review responses are similarly valuable, and for a less obvious reason. When you respond to reviews with thoughtful, considered replies that address the substance of what the reviewer said, you’re creating a body of structured, question-and-answer content that AI tools can draw from. It’s one of the few places where your brand voice appears in genuine dialogue and dialogue is exactly the format AI tools are trained to trust.
The weekly post cadence matters too. GBP treats fresh content as a positive signal, and the posts you publish there even short ones contribute to the freshness score that influences how prominently you appear in AI-generated local results.
Your First Actions on Each Platform
Knowing which platforms matter is one thing. Knowing where to start is another. Here are the first moves we’d recommend on each.
Reddit — Week 1: Don’t post anything. Spend the first week reading. Identify three to five subreddits that are genuinely relevant to your industry. Read the top posts, understand the community norms, notice what kinds of contributions get upvoted and what gets ignored. Then start commenting, not promoting, commenting. Answer questions where you have genuine expertise. Agree, disagree, add nuance. Build karma slowly and deliberately. Promotional content comes much later, if at all.
LinkedIn — Week 1: Audit your existing content. Look at your last ten posts and ask honestly: does each one directly answer a question your audience is asking? If most of them are announcements, reposts, or vague thought-leadership pieces, that’s the pattern to break. Draft one long-form article structured around a specific question — “Why do most [industry] campaigns underperform?” or “What should business leaders actually be measuring in 2026?” — and publish it with a clear structure: question, context, answer, takeaway.
Google Business Profile — Week 1: Log into your GBP dashboard and do three things. First, go to the Q&A section and add ten questions and answers covering the things your prospects most commonly ask. Second, check that your service descriptions are written as answers to questions rather than as sales copy eg. “We help purpose-led businesses build marketing strategies that generate measurable revenue” reads very differently to “Award-winning digital marketing agency.” Third, set a weekly reminder to publish a short post every Monday.
The Principle That Ties All Three Together
There’s a pattern underneath all of this that’s worth naming explicitly: AEO rewards content that answers questions directly, in formats that feel like genuine human knowledge rather than brand messaging.
Reddit is peer conversation. LinkedIn is professional insight. Google Business Profile is structured business information. All three are formats that AI tools have been trained to treat as trustworthy — because they are the kinds of content that real humans, not marketing departments, produce.
The businesses that will win at AEO are the ones that genuinely invest in being helpful — not just visible. That’s a shift that requires a different mindset more than a different tool set.
And it’s a shift that suits purpose-led businesses particularly well. When your genuine value aligns with what you’re saying publicly, that authenticity is readable by both human audiences and the AI tools that increasingly shape what they see.
Three platforms. One principle. A head start while most of the market is still asking the wrong question.
