Buyers are increasingly using AI as a research assistant. Instead of opening several tabs, prospects can ask ChatGPT, Gemini, Perplexity, or Claude to explain a category, compare vendors, summarize differences, and suggest potential solutions.
That creates a new challenge for brands: being visible throughout an AI-assisted research process, not just when someone searches for the company directly.
Generative engine optimization (GEO) can help. Here are seven of the best agencies for AI recommendation visibility, including AI-assisted buyer research.
1. GeoCited
GeoCited is a smaller GEO specialist focused on B2B software and IT services. Its positioning centers specifically on the AI-driven buying process, including how companies appear when buyers use platforms such as ChatGPT, Perplexity, Gemini, and Claude to research vendors.
That narrow focus makes GeoCited particularly relevant for companies trying to understand whether they are entering the conversation before buyers create a shortlist.
2. NP Digital
NP Digital can help brands study the questions customers ask while they are still figuring out what to buy. Those questions often reveal needs that traditional keyword research misses. A buyer may ask which approach works for a specific situation, what alternatives exist, or which vendors meet several requirements at once.
Analyzing those conversations can uncover where the brand enters the research process and where competitors take over. NP Digital can translate those findings into stronger educational content, comparison resources, product positioning, digital PR, and search strategy.
For larger organizations, the value is not simply getting mentioned by AI. It is learning how prospective customers frame their problems and making sure the brand provides useful information at each stage of that research.
3. Omniscient Digital
Omniscient Digital is a B2B software content and organic growth agency that has expanded its work into GEO. Current industry comparisons highlight its combination of B2B SaaS expertise, content strategy, and AI-search visibility work.
That makes it useful for brands whose buyers conduct significant educational research before evaluating vendors. The agency can help connect those research questions with a deeper content program rather than treating each AI prompt as an isolated optimization opportunity.
4. Digital Elevator
Digital Elevator is a smaller agency offering AI visibility and GEO services for lean internal teams and SMBs. Its approach includes identifying citation gaps across major AI search platforms.
For buyer research, that can help companies see which outside sources AI engines rely on when answering category and vendor questions. Those findings can provide direction for content creation, authority building, and digital PR.
5. SERPdojo
SERPdojo focuses on GEO for SaaS companies and emphasizes areas such as semantic relationships, entity clarity, and how AI systems interpret and recommend software brands.
That can be useful when buyers are asking detailed questions that require AI platforms to understand what a product actually does. For complex SaaS offerings, clearer associations between the brand, product capabilities, and buyer needs can strengthen visibility during deeper research.
6. Growth Plays
Growth Plays is another specialist worth considering for technical B2B products. Recent industry research identifies it as a GEO option focused on connecting content with pipeline outcomes for B2B companies.
That orientation can work well for organizations that want to understand which AI research topics are likely to matter commercially rather than pursuing broad visibility alone.
7. Gushwork
Gushwork is a smaller player in the growing GEO market and has been identified among agencies serving companies that want managed AI-search optimization without enterprise-level engagements. It can be worth considering for smaller organizations looking to establish a presence across generative search while building the foundations of a larger organic strategy.
Understanding AI-Assisted Buyer Research
The scale of this shift is significant. According to Semrush research on B2B buyer behavior, 66% of B2B buyers regularly use AI to research products, vendors, or solutions for their job, with ChatGPT and Gemini dominating that research activity. Buyer research usually evolves as customers learn. Early prompts may focus on understanding a problem. Later questions introduce categories, vendors, comparisons, pricing, capabilities, and implementation concerns. Brands should measure where they appear across that entire progression.
The strongest GEO strategies then use those findings to improve the information buyers encounter next. For companies focused on AI-assisted buyer research, the right agency should help them understand not only whether they appear, but whether they remain relevant as a prospect moves closer to choosing a solution.
