B2B research habits are shifting fast. Decision makers now consult AI tools such as ChatGPT and Perplexity before filling out a form or booking a call. That change alters how brands earn visibility and trust.
Traditional rankings still matter, but citations and references inside large language models carry growing weight. This article reviews leading agencies that build SEO strategies around AI-driven discovery.
It outlines their core services, strengths, and limitations, with a focus on LLM influence. For B2B companies competing in crowded markets, understanding this landscape helps guide smarter investment in search visibility.
How We Picked The Agencies
AI-driven research has changed what “SEO success” looks like for B2B brands. Buyers now validate vendors inside ChatGPT, Perplexity, and AI Overviews, often before they ever click a result. So we chose agencies that can improve visibility inside LLM answers while still strengthening the classic foundations that make that visibility possible.
- LLM visibility focus: Agencies needed a clear capability around citations, mentions, entity recognition, and content formatting for AI extraction, not just keyword rankings.
- Technical SEO strength: Crawlability, site structure, performance, and structured data matter more than ever because LLMs rely on clean, accessible source content.
- Authority building: We favored firms that integrate digital PR, backlinks, and credibility signals (E-E-A-T) since trust heavily influences what gets cited.
- Reporting and measurement: Preference went to agencies that track AI visibility (mentions/citations, prompt-level performance, sentiment, referral sessions) alongside traditional SEO metrics.
- Fit by business model and region: This list includes B2B-focused agencies (Nine Peaks Media, Exposure Ninja), experimentation-led GEO teams (Impression), technical SEO + LLMO specialists (SEO Berlin, StudioHawk), and region-strong providers for Asia-Pacific and Australia (First Page Digital, Prosperity Media), plus broader multi-channel options (Climb Online, Sisu Digital).
The goal: help B2B teams shortlist agencies based on how buyers research today, not outdated search assumptions.

Questions To Ask Your SEO Agency
These questions will quickly reveal whether an agency can improve LLM influence (citations/mentions) and translate that into measurable business outcomes.
FAQ 1: What’s “Perplexity optimization” in practice?
It’s making your site and content easier for Perplexity to extract and cite through clean technical foundations, structured answers, topical coverage, and stronger authority signals.
FAQ 2: Can any agency guarantee citations in AI tools?
No. Platforms change, and citations are not guaranteed. A credible agency can improve the inputs that increase citation likelihood and show transparent progress over time.
FAQ 3: Do citations matter if they don’t always drive clicks?
Yes. AI answers often mention brands without linking. Mentions still shape consideration and can influence branded searches, shortlist decisions, and trust.
FAQ 4: Is technical SEO still important in an AI-first world?
Absolutely. LLMs still rely on crawlable, well-structured, trustworthy pages. If your site can’t be reliably accessed and understood, you can’t be consistently referenced.
How To Choose The Right Agency
Choose based on your primary constraint:
- If you’re a B2B brand needing structured LLM visibility + traditional authority building, pick an agency that combines technical SEO, entity work, and citation strategy in one system (Nine Peaks Media-type fit).
- If you want AI visibility tied to measurable revenue outcomes, look for experimentation-led GEO with PR integration (Impression-type fit).
- If you need LLM audits and ongoing citation monitoring, choose agencies with dedicated AI visibility tooling and reporting (Exposure Ninja / SEO Berlin-type fit).
- If region matters (APAC/Australia), prioritize agencies with proven market footprint and localized execution (First Page Digital / Prosperity Media-type fit).
Conclusion:
AI platforms are reshaping how B2B buyers compare vendors and validate claims. Agencies that combine technical SEO, structured data, digital PR, and citation strategies are better positioned to influence those conversations.
Some focus on enterprise markets. Others serve regional brands or ecommerce businesses expanding into AI-driven discovery. The right partner depends on geography, budget, and growth priorities.
For organizations seeking structured LLM visibility alongside traditional authority building, Nine Peaks Media offers a focused approach built around generative search behavior. As AI research becomes standard, strategic visibility inside these systems will define competitive advantage.
