Guide: How to Choose an AI Search Agency for B2C

The introduction of AI Search platforms (ChatGPT, Gemini, Claude, etc.) has created a new category of agency services and has changed the playbook of a successful organic search strategy. This has made it harder than it should be to find the right B2C AI Search agency.

Some agencies have made genuine improvements and offer sophisticated AI search strategies, while others have simply added “AI” to their pitch deck without actually changing how they operate.

This guide is for marketing leaders evaluating AI search partners. Whether you’re starting from scratch, benchmarking a current relationship, or trying to avoid another expensive mismatch.

What Good AI Search Looks Like and Where It Differs from SEO

Before evaluating any agency, you need an understanding of what you’re searching for.

Traditional SEO is about ranking within the links of a search results page. Keyword rankings and traffic are your core signals.

AI Search works differently. With AI Search, you’re trying to become part of the recommendation, regardless of whether or not your website is listed. LLMs don’t return a list of ranked websites, it synthesizes an answer, often without requiring a click at all. Your goal is to be mentioned within their recommendation or included as one of the sources of information.

This distinction matters when evaluating agencies because the strategies required are different. Core SEO elements are still a prerequisite, but beyond that, AI search visibility depends on a variety of different factors. An agency optimizing for traditional rankings is not necessarily equipped for this.

A capable AI search agency should have clear answers for each of these practice areas:

• Technical SEO & AI Crawlability: Ensuring AI bots can access and extract your content is a fundamental non-negotiable.
• Content Strategy: Build content that matches how LLMs process and synthesize information, including query fanout coverage.
• Offsite Authority Building: Earning 3rd-party credibility signals that influence which sources LLMs trust.
• AI Visibility Measurement: AI search tracking is an entirely different game and requires a more modern SEO measurement approach.

If an agency you’re evaluating doesn’t have a clear, specific approach for each of these, that’s your first signal.

What to Watch For During the AI Search Sales Process

AI Search is still an emerging discipline, which means the quality gap between agencies is wider here than in traditional SEO. There are clear signals to watch for before you sign anything.

No Change in Approach

Many agencies don’t have an understanding of how to succeed with AI Search, so they revert to “Good SEO is good AI Search.” This is incorrect. Good SEO is a requirement of good AI Search, but it doesn’t provide full coverage. They might talk about AI Overviews and LLMs, but the actual work they deliver looks identical to what they were doing years ago.

A credible agency will have a specific, concrete answer about where SEO & AI Search overlap and where they diverge. Vague language about “the evolving landscape” without specifics is a red flag.

The Role of Audience Research

One of the biggest differences between traditional and AI search is the level of personalization that comes along with AI search. This comes in the form of searches entered into LLMs, as well as the results they receive.

AI Search platforms offer the ability to provide details specific to that user, in order for LLMs to provide a response as tailored to their specific needs as possible. A good AI Search agency understands that personalization is directly related to audience research and makes a direct connection between your content strategy and your target audience.

AI Search Measurement

AI generated answers often provide enough information that users don’t need to click into a website (zero click searches). As a result, organic traffic is declining, but that doesn’t mean the impact of organic search is declining. 

An agency’s reporting framework should include a heavy emphasis on AI search visibility in the form of brand mentions/citations across a wide set of target prompts. However, the strong agencies are the ones that focus on this broader reporting framework and connecting it to the business impact.

Avoid agencies that lead with supporting metrics, rather than business outcomes. Supporting metrics like AI visibility & traffic can help identify opportunities, but they can’t be relied upon for gauging success.

Rigid vs Flexible Delivery Models

AI search is not a stable channel. These platforms are evolving at an alarming rate, and the strategies that worked six months ago may not work tomorrow.

Agencies pitching fixed scopes of “X AI Search assets per month” are prioritizing their own operational efficiency over results. The right approach is adaptive. Content volume, technical priorities, and offsite opportunities should shift based on what the channel requires, not what’s easiest to scope and staff.

Ask how the agency recalibrates strategy when AI search behavior changes. Look for partners that show an ability to flex when needed in order to drive success, not output.

The Right AI Search Agency Acts as a Team Member, Not a 3rd Party

The AI Search landscape is changing at such a fast pace that no agency can claim to have fully solved it. The ones worth working with are up front about what’s working in their experience. They also have a clear perspective on where they believe the industry is headed.

Look for an agency that wants to be a strategic partner, not an execution arm. Is the agency willing to challenge you? And are they willing to be challenged when their assumptions are wrong? These are the agencies that want to see you succeed, rather than prioritizing their own business.

AI Search is still early enough that the agencies doing the best work are the ones genuinely investing in understanding how LLMs behave and building strategies around that understanding. That shows up in the specificity of what they say.
