How to get cited by ChatGPT and Perplexity when your buyers ask about your maritime category

Every quarter we audit LLM visibility across maritime categories for our clients: ship management, port agency, marine equipment, classification societies, fleet management software, marine insurance, offshore services. We run the same thirty to fifty prompts a real buyer might ask through ChatGPT, Copilot, Gemini and Perplexity, score where each client appears and look for what differentiates the businesses that get cited from the ones that don’t.

Four patterns hold across categories.

1. Structural quality matters more than volume. The companies cited most often aren’t the ones with the most blog posts; they’re the ones whose service pages are well-structured, factually specific, schema-tagged and self-contained. A site with twelve excellent pages on its core capabilities consistently outperforms one with two hundred shallow ones.

2. Brand-authority signals are concentrated. Mentions in TradeWinds, Lloyd’s List, Splash, gCaptain or marine industry directories show up disproportionately in citation traces. A single feature in a tier-one publication outperforms a dozen guest posts on lower-authority sites. This is consistent with how we see Google rank, but the LLM weight on these sources appears even higher.

3. Specificity gets quoted; generic copy gets ignored. “We provide tailored ship management solutions” is invisible. “We hold ISM DOC certification for tanker, bulker and gas carrier vessels above 5,000 GT, with offices in Limassol, Singapore and Hamburg” is citation-grade. LLMs prefer claim-and-evidence pairs they can extract and quote in a generated answer.

4. Schema implementation pays off. Sites with proper Organization, Service and FAQ schema show up in citations more often than sites without, even when content quality is comparable. Schema isn’t magic; it just makes you legible to systems trying to extract structured information at scale.

What this means in practice

If you’re trying to move the needle on LLM citation rate for your maritime business, the four highest-impact actions are usually:

• Rewrite your top four service pages with claim-and-evidence structure, specific certifications, regional capabilities and named integrations.
• Implement Organization, Service, FAQ and BreadcrumbList schema site-wide. Use Google’s Rich Results Test to validate.
• Earn one or two genuine features in tier-one trade press over the next twelve months. Generic outreach won’t work; offering a journalist a usable data point will.
• Run quarterly LLM-visibility audits so you can see whether the work is compounding. The lag between investment and citation movement is two to three months.

The discipline is new. The standards are unsettled. The companies that take it seriously now will have a defensible position by the time it’s mainstream.
