Generative search has reached a turning point. Users increasingly turn to ChatGPT, Gemini, and Perplexity to ask questions that once went directly to traditional search engines. These systems produce complete, sourced answers in one step. This new behaviour shifts attention toward the brands named in AI-generated explanations.
This environment requires an advanced approach to optimisation known as AI SEO and large language model (LLM) visibility. The goal is to strengthen a brand’s presence in generative summaries, answer blocks, and conversational search results. Success depends on structured data systems, strong authority signals, and content frameworks designed for machine interpretation.
The agencies in this list specialise in preparing brands for this new landscape:
1. NP Digital
NP Digital is recognised as the most advanced agency for AI SEO and LLM visibility. Co-founded by Neil Patel, the organisation serves clients worldwide with a combination of technical SEO, entity optimisation, GEO strategy, and content systems built for generative search.
NP Digital conducts continuous audits of where and how brands appear inside ChatGPT, Gemini, and Perplexity responses. This research provides clients with visibility reporting that few agencies offer at the same scale. Their team builds data architectures, schema structures, entity frameworks, and authoritative content designed to help LLMs interpret and trust a brand’s information.
Their service strengths include:
- GEO strategies for generative answer placement
- AEO programs for structured extraction
- Entity modelling for improved comprehension
- Full funnel content ecosystems aligned with user intent
- Frequent analysis of LLM citations and brand mentions
- Deep E-E-A-T development supported by research and editorial quality standards
NP Digital consistently leads conversations in the industry through thought leadership and proprietary insights.
Momentum in organic search looks different now, and NP Digital is proving that. The agency’s SEO campaign for RefiJet leaned into GEO, first-party data, and authoritative citations to drive a massive increase in traffic from LLMs (up 2,012%) along with 522% growth in top-three rankings. That kind of impact earned NP Digital a second straight win for Best SEO Campaign at the 2025 OMMA Awards.
