We help position your brand as the one AI tools recommend in your category
Underscore is a boutique AI SEO agency in Singapore that helps established SMEs improve how they show up in ChatGPT, Claude, Gemini, and other AI-powered search tools. Through our 7 Signals Framework, we work on the infrastructure that determines whether AI cites and recommends your business.
Your customers are still researching. The way they do it has changed.
Your SEO is working. So why does traffic feel off?
Your SEO is solid. But results feel less predictable. You need a roadmap for what's changed.
Everyone's talking about AI search. You're still not sure what to do.
You've seen the stats. But without clarity on where you stand today, you don't know what moves the needle.
You're noticing shifts. You're not sure how to respond.
You're seeing new patterns in traffic and queries. But responding without guidance risks what already works.
AI surfaces your brand in two ways. Most businesses only think about one.
These two outcomes are related, but they are not interchangeable. A brand can be cited without being recommended. It can also be mentioned without owning the underlying source.
We engineer for both.
Introducing our 7-signal framework for answer engine optimisation
The 7-Signal
These signals work as a system, not a checklist. Each one reinforces the others. We start with Brand Signal as the foundation, then strengthen the layers that shape how AI systems interpret, trust, and recommend your business.
We work best with businesses where trust, clarity, and discoverability shape demand.
Best suited for
- Established businesses with a clear offer and a credible track record
- Brands in categories where customers compare options carefully before choosing
- Teams that have already invested in their website, content, or digital presence
- Businesses that want to improve how AI tools understand, describe, and recommend them
- Leaders looking for a sustained strategic engagement
Less Suited For
- Businesses looking for a one-off tactical fix
- Teams focused only on publishing AI-generated content at scale
- Companies looking purely for SEO execution or paid acquisition
- Businesses that are not ready to clarify their positioning first
Complimentary 7-day AI Visibility Snapshot
At no cost, we run a focused assessment of how AI systems currently see your brand. This is the same diagnostic we use to evaluate fit and prioritise what matters.
- Visibility snapshot across ChatGPT, Perplexity, and Google AI Overviews
- Brand representation review
- Competitive context across your industry
- Infrastructure gap analysis mapped to the 7 Signals
- A walkthrough call to discuss findings and fit
The Snapshot gives you a clear picture of where you stand today. The full engagement goes deeper, tracking changes over time and engineering improvements across all 7 signals.
One industry. One client. Full commitment.
We do the opposite of volume-based agencies. We take on only one active client per industry. That means no competing mandates, no split incentives, and no diluted focus.
Foundation
We define how your brand should be understood, who you serve, and what makes your business credible in category-level AI discovery.
Signal Engineering
We strengthen the content, authority, technical infrastructure, and supporting assets that shape visibility across answer engines.
Measurement
We track changes in visibility, citations, referral patterns, and how your brand is being described across key AI platforms.
If we work together, your category is yours for the duration of the engagement. That is how we protect the quality of the work and the value of the opportunity.
FAQ
AEO (Answer Engine Optimisation) ensures AI tools like ChatGPT, Perplexity, and Google AI Overviews can understand and recommend your business accurately when buyers ask for solutions. Over 60% of searches now end without a click because people get answers directly from AI. If these tools can't explain what you do or why you're credible, you're invisible during the research phase.
We decline. For the duration of your engagement, your industry slot is exclusively yours. We will not take on a direct competitor. This is fundamental to how we operate.
The AEO Partnership is a 6-month strategic engagement. Pricing is discussed during the consultation call after we've reviewed your Snapshot results and understand the scope. We work with established SMEs, not enterprise budgets, and structure engagements accordingly.
AEO is additive. We layer in structured improvements like better content hierarchy, schema markup, and clearer positioning that help both AI and humans understand your value. We start by auditing what's already performing well, then make targeted improvements to high-impact pages. The goal is to enhance AI visibility while protecting what you've spent years building.
SEO helps you get found in search results. AEO helps you get recommended by AI. They work together. Your existing SEO builds authority that AI respects, while AEO ensures AI can understand your site, extract accurate information, and confidently recommend you when buyers are evaluating options.
Early signals typically appear within 4-8 weeks once optimisations are live. You'll notice improved brand descriptions and initial citations in AI answers. Consistent results, like regular visibility across multiple AI platforms and measurable lead flow, usually build over 3-6 months. This is why the engagement is 6 months.
One slot per industry. See if yours is open.
We'll assess how AI systems currently see your brand, identify the infrastructure gaps that matter, and show you what's possible.
