Search increasingly includes AI-generated answers and conversational assistants that cite or mention sources. Many agencies now sell services under labels such as AI search optimization, generative engine optimization or answer engine optimization. The field is new, evidence is thin and terminology is unsettled. That makes claims easy to inflate.
This guide helps you separate reasonable work from marketing.
What is reasonably true
- People use AI-driven interfaces to ask questions that once went to traditional search.
- These systems draw on a mix of training data, live retrieval and cited sources, and their behavior differs between products and changes over time.
- Clear, well-structured, accurate content from credible sources is more likely to be useful to such systems, as it is to human readers.
- Brand mentions and citations in AI answers can be observed, at least on a sampling basis.
What is uncertain
- Controllability. No agency controls what an AI system says. Outputs vary by prompt, user context, location and time.
- Repeatability. The same question can produce different answers on different days or even different runs.
- Attribution. Visits from AI assistants may be hard to separate in analytics, and influence without a click may not be measurable.
- Causality. Proving that a specific change caused a mention is difficult.
- Stability. Techniques that work for one system may stop working after an update.
Any agency that presents certainty about these areas deserves scrutiny.
Claims to treat with caution
- "We guarantee you will be recommended by AI assistants."
- "Our proprietary method gets you into AI answers."
- "AI visibility scores" with no disclosed method.
- Claims of special relationships with AI providers.
- Case studies with a single screenshot of one prompt and one answer.
- Treating AI search as wholly separate from, or a replacement for, sound SEO fundamentals without evidence.
- Fear-based pitches that your business will disappear without immediate purchase.
What reasonable work looks like
Credible services in this area tend to overlap with good SEO practice:
- Content clarity and accuracy. Direct answers, defined terms, up-to-date information.
- Entity and brand consistency. Consistent naming and descriptions across your site and reputable external sources.
- Structured data and technical accessibility so content can be retrieved and understood.
- Authoritative coverage. Mentions in credible third-party publications and references.
- Monitoring. Sampling prompts relevant to your market to see how your brand and competitors are described.
- Corrections. Identifying inaccurate statements about your business and fixing the source information.
See Technical SEO vs Content SEO for how these map to standard disciplines.
How to evaluate monitoring and reports
If an agency provides AI visibility reporting, ask:
- Which systems are tested, and in which versions or modes?
- How many prompts, how were they chosen and are they fixed over time?
- How many runs per prompt, to account for variation?
- Are results reported as ranges or frequencies instead of single screenshots?
- Is branded and unbranded prompt performance separated?
- How are citations and unlinked mentions distinguished?
- How does this connect to traffic, leads or sales?
See Understanding SEO Reporting for general reporting standards.
Evidence to request
- Methodology document in plain language.
- Case studies that describe actions, baselines, measurement and limitations. See Evaluating an SEO Case Study.
- Examples of what they decline to promise.
- Client references who can speak to results and limitations.
Questions to ask
- What exactly will you do differently from standard SEO?
- What can you measure, and what cannot be measured?
- What happens if answer behavior changes after an update?
- Who is responsible for content accuracy?
- How do you avoid tactics that could harm our standing in traditional search?
Add these to the list in Questions to Ask Before Signing.
Contract cautions
- Do not accept outcome-based promises you cannot verify.
- Keep terms short or project-based while the field is changing; see Monthly Retainer vs Project Pricing.
- Ensure you own the content, data and monitoring outputs.
How this site handles claims
Agency listings here mark whether a claim comes from the agency's own site, a published case study or independent corroboration. For a new area like AI search visibility, most claims will fall in the first category. Sponsorship never buys verification. Use the labels to decide how much weight to give a statement, and browse the directory to compare how agencies describe their offerings.
