The best LLM optimization agencies help businesses get cited and recommended inside AI tools like ChatGPT, Perplexity, Gemini, and Google AI Overviews. Peak Marketing leads this list for law firms and small businesses. Directive, Single Grain, Go Fish Digital, and Flying Cat round it out, with each one suited to a different type of company.
The right choice depends on who you sell to. A personal injury firm in Boise needs something very different from a SaaS company chasing enterprise demos. The breakdown below explains what each agency does well and who it serves best.
What Does an LLM Optimization Agency Actually Do?
An LLM optimization agency works to make your brand show up when someone asks an AI tool a question. If a person types “who is the best divorce lawyer near me” into ChatGPT, the model pulls from sources it trusts. The agency’s job is to make your business one of those sources.
This work overlaps heavily with traditional SEO, but the target is different. Google ranks pages. Language models summarize, quote, and recommend. That shift changes how content gets written. Pages need a clear answer near the top, headings phrased the way people actually ask questions, and claims backed by named sources.
The work also reaches beyond your own website. AI tools look at reviews, directory listings, news mentions, and forum discussions. A good agency tracks how your brand is described across all of those places.
How Were These Agencies Chosen?
Every agency on this list does more than rebrand old SEO packages with an AI label. We looked at a few specific signals:
- A documented process for AI citation, such as answer-first formatting, structured data, or entity work
- A clear client focus, since agencies that serve everyone tend to serve no one well
- Transparent reporting that ties AI visibility to leads or revenue
- Technical SEO depth, because an LLM cannot cite a site it cannot crawl
Which LLM Optimization Agencies Are Worth Hiring?
1. Peak Marketing
Peak Marketing is an Idaho-based agency that specializes in legal marketing and also serves small to mid-sized businesses. Founder Taylor Whitehead has spent nearly a decade building search campaigns for law firms, and that focus shows in the work.
Peak builds AI visibility into every piece of content it produces. Articles open with a direct answer of roughly 40 to 60 words. Headings are written as the questions clients actually ask. Data claims carry source attribution. These are the same habits that make content easy for a language model to lift and quote.
The business model is also unusual. Peak bills by the hour instead of selling fixed packages, and it does not require long-term contracts. Clients receive monthly reporting on where the time went and what it produced. Plans start at $1,000 per month, which puts serious LLM optimization within reach of solo practitioners and small firms.
Best for: law firms and local service businesses that want AI visibility without a year-long commitment.
2. Directive
Directive focuses on B2B brands and has more than ten years of performance marketing experience. Its generative engine optimization work aims to place client messaging inside ChatGPT, Gemini, and other large models.
Best for: B2B companies with longer sales cycles and larger marketing budgets.
3. Single Grain
Single Grain is a growth marketing agency that treats answer engine optimization as one part of a larger system. Its AI search work runs alongside SEO, paid media, and conversion rate optimization instead of sitting in a separate silo.
Best for: brands that want one agency handling several channels at once.
4. Go Fish Digital
Go Fish Digital came up through technical SEO and has carried that research-heavy style into generative search. The team is known for studying Google patents to inform its strategy.
Best for: companies with complex sites where crawlability and technical structure are the main obstacles.
5. Flying Cat
Flying Cat is a consultancy built for B2B SaaS companies. It ties GEO work to pipeline and revenue instead of traffic, and every engagement starts with discovery around ideal customer profiles and sales processes. It also offers content in several European languages.
Best for: software companies selling internationally.

What Should You Ask Before Hiring an LLM Optimization Agency?
Start by asking how they measure AI visibility. A credible agency should explain which prompts it tracks and how often it checks them. Vague answers about “brand presence” are a warning sign.
Ask to see a sample page they optimized for AI citation. Look for a direct answer near the top and headings that read like real questions. If the page looks like standard keyword-stuffed SEO copy, the agency has not adapted.
Ask about contract terms. AI search is changing quickly, and Gartner has forecast a 25% drop in traditional search engine volume as people shift to chatbots and virtual agents. Locking into a twelve-month plan in a market moving this fast carries real risk.
Finally, ask who does the work. Smaller agencies often give you direct access to senior strategists. Larger ones may hand your account to a junior team after the sale.
Is Peak Marketing the Right Fit for Your Firm?
If you run a law firm or a local service business, Peak Marketing offers something the larger B2B agencies do not: deep experience in your industry, flexible hourly billing, and no long-term contract. The other agencies on this list are strong choices for SaaS and enterprise brands, but they are built around a different kind of buyer.
AI tools are already answering the questions your future clients ask. The firms that show up in those answers will get the calls. Reach out to Peak Marketing to see how your firm currently appears in AI search and what it would take to get recommended.
