Most AI visibility work still starts and ends on the brand’s own website.
Structured data, clean headings, a FAQ block, a page thatanswers the question directly. All of it useful, and none of it sufficient, because when a large language model answers a question it is overwhelmingly quoting somebody else. The listicle, the review roundup, the Reddit thread, the trade publication, the comparison page on a competitor’s blog. If your brand is missing from those sources, or is present but described wrongly, no amount of on-site tidying fixes it.
That gap has produced a distinct service category. These firms do not optimize your site. They go and get your brand mentioned, accurately, in the external sources the models draw on, using outreach, digital PR, original research and paid or earned placement. Some are venture-backed startups built for this single job. Others are established digital PR agencies that recognized their existing mechanism was suddenly the most direct route to AI visibility available.
Below are twelve AI brand mention and citation services worth knowing, what each one actually does, and what they charge where that is public. Every entry was verified against the company’s own site rather than a directory listing, which matters in a category currently drowning in auto-generated agency roundups.
A quick orientation before the detail. Pricing is shown only where the company publishes it.

Noble is the purest expression of this category, because mention placement is not part of the product, it is the entire product. The company sells two things. New Mention gets a brand added to an article that AI systems already cite but that currently does not mention it. Mention Refresh corrects an existing mention that is inaccurate, out of date, or ranks the brand unfairly low. Noble identifies the citation gap, handles publisher outreach and negotiation, and manages the process until the mention is live.
The pricing model is unusually transparent for this space. Plans start at $2,000 a month on an annual commitment, with a per-mention cost averaging around $400 all in, and unused budget refunded rather than absorbed. Named clients include Webflow, ZoomInfo, Zendesk, Ramp, Brex and Sendoso, which is a serious roster for a team still in single digits. If you want to buy a specific number of placements rather than a general retainer, this is the closest thing to a unit-priced product in the category.
uSERP is a Denver-based earned placement agency that came from the link building world and has retooled its targeting around the domains large language models actually cite. The pitch is content-led outreach that wins placements in publications a brand could not reach on its own, with an explicit filter for AI and LLM cited domains rather than raw domain authority alone.
The client list is the strongest signal here. Monday.com, Robinhood, CrowdStrike, Freshworks, Preply and Nav are not brands that buy speculative services, and uSERP reports having worked with more than 575 clients. The team is fully in-house rather than outsourced, which matters when the deliverable depends on relationships with editors. Pricing runs $5,000 to $25,000 and up per month with a three-month minimum, so this is the enterprise end of the market rather than an experiment.
Reboot Online has productized the offsite half of generative engine optimization under the name AiPR, a trademarked programme built specifically around the signals that sit outside a brand’s own website. The framing is precise: the evidence AI systems use comes from coverage, mentions, expert commentary, original data and category associations spread across the web, and AiPR is the work of building those.
What sets Reboot apart operationally is that it publishes a floor price, GBP 8,500 a month, and caps how many programmes it takes each quarter. Publishing a minimum is rare in this category and does useful filtering on both sides. The agency has a long track record in SEO experimentation and digital PR before the AI pivot, with TUI among the case studies on the AiPR page itself.
Impression is the largest and most established firm on this list, running out of Nottingham with additional offices in London, Manchester and New York. Its digital PR practice predates the AI search shift by years, and the positioning now leads with the connection directly: authority programmes that increase AI visibility, built on authoritative coverage, expert perspectives and credible brand mentions across trusted publications.
The client roster leans consumer and mid-market rather than pure B2B SaaS, with Lotus, Funky Pigeon, Marmalade, Sambla, Queensmith and And So To Bed among those named publicly. For a brand that needs sustained coverage volume rather than a handful of targeted placements, the depth of an agency this size is the argument. Pricing is not published, which is normal at this end of the market.
JBH is a Manchester digital PR agency founded in 2013, with a second office in London, that has broken its GEO service into components rather than selling it as a single vague product. One of those components is named Offsite PR for Brand Mentions, and the description is refreshingly mechanical: targeted media outreach to secure authoritative brand mentions in leading and relevant publications, increasing the supply of information that language models and search engines hold about the business.
That framing, treating mentions as supply of information rather than as links, is the correct mental model for this work and relatively few agencies articulate it that plainly. JBH pairs an SEO director and a PR director at the top of the practice, which is the structure you want when the deliverable has to satisfy both an editor and an algorithm. Client work includes Gousto, Tails.com and Select Car Leasing.
MADX Digital works exclusively with B2B SaaS companies, and the narrowness pays off in how specifically the offer is described. Their GEO service is built on offsite signal building: earned mentions, podcast appearances and dataset contributions, aimed at producing brand mentions, earned citations and third-party references in the publications and platforms AI models weight most heavily.
The engagement model is a 90-day sprint followed by six or twelve month retainer options, starting from $2,500 a month, which makes it one of the more accessible entry points here for a company that wants to test the channel before committing a year. More than 50 active SaaS clients are claimed, with MoonPay, Veed.io, Postalytics and Kurve named. If your buyers are software buyers, the category focus is worth something on its own.
Digitaloft is a small Cumbria and Manchester agency with a client list well above its weight class, including Booking.com, Emma, Sopro, GO Outdoors and DeliVita. Its GEO practice is explicitly an extension of its digital PR work, and the agency states the dependency plainly: generative visibility is measured in citations, mentions and brand presence inside AI answers, and it depends on what others say about you in relevant, high-authority publications.
That is a more honest description of the causal chain than most agencies offer, and it sets expectations correctly: the work is earning editorial coverage, and AI visibility is the downstream effect. With a team of roughly a dozen, Digitaloft is a better fit for brands that want senior attention on a focused campaign than for those needing high-volume output across many markets at once.
Polaris runs from London, Dublin and New York, focused on B2B technology, and has given Digital PR for AI Search a dedicated service page rather than a bullet on a broader GEO page. The methodology is broken into named parts, and the breadth is the point: digital PR and earned brand mentions, authority building and unlinked mention reclamation, presence in AI-cited communities, and reviews, directories and third-party profiles.
Unlinked mention reclamation and third-party profile work are the two elements most often skipped elsewhere, and both matter more for AI citation than for traditional search, because a model reading a sentence about your product does not need a hyperlink to absorb it. Polaris publishes a cybersecurity case study with Six Degrees. Pricing is not disclosed, and the client roster is thinner in public than several others here.
Embarque describes the mechanism more directly than anyone else in this roundup: they get your brand into listicles, Reddit threads and other sources language models frequently cite for your target queries. There is no abstraction layer in that sentence, which is a good sign in a category where a lot of copy is written to sound sophisticated rather than to be checkable.
The team is small and distributed with no stated headquarters, which will matter to some buyers and not others, but the operating history is real with more than 200 client partnerships and named work including Riverside.fm, Flick, SignWell and MentorCruise. Pricing runs $3,000 to $8,000 a month with a six-month minimum recommended, positioning it between the entry-level and enterprise ends of this list.
Prosperity Media is a sixteen-person Sydney agency founded in 2012 by James Norquay, serving Australia, Singapore and the United States. It combines SEO, GEO, content and digital PR, and has published substantive work on how digital PR influences language models and AI Overviews rather than simply adding GEO to a services menu.
The enterprise client list is the differentiator, with IAG, Danone, PepsiCo, Binance, HubSpot and Oneflare among those named. For brands that need APAC media relationships specifically, there are few alternatives on this list with comparable regional depth. The mention work sits inside a broader SEO offer rather than standing alone as a product, which is worth knowing if you want to buy placements and nothing else.
Fractl, based in Delray Beach, Florida, has spent more than a decade doing one thing well: producing original data studies and placing them with journalists, which yields top-tier coverage and, in their words, an extremely authoritative brand mention. The firm reported 555 placements in 2025, and clients have included Adobe, Discover and Paychex.
Fractl has also published some of the more serious original research on how AI systems select and cite sources, arguing that digital PR is the engine of generative visibility and that winning mentions in the right publications shifts what the models themselves hold. The caveat is that the AI framing lives largely in their research and measurement work rather than in a packaged AI-citation product, so you are buying data-driven digital PR that happens to be well aimed at this outcome, rather than a service built for it from scratch.
Bubblegum Search, based in Surbiton in Greater London, describes a workflow that maps neatly onto how this work should actually run: track where a brand appears across ChatGPT, AI Overviews and AI search, identify the specific source pages influencing those answers, then secure brand mentions on those sources. Diagnose, then place.
It is a small agency and it names no clients publicly, which is the main reservation to register. The entry point is a free AI visibility snapshot, which is a sensible way to test whether the diagnosis half is any good before committing to the placement half. For a brand with a modest budget that wants source-level targeting rather than broad coverage, it is worth a conversation.
This is the first and most important filter, because the two get marketed in almost identical language. A monitoring platform tells you that ChatGPT recommends three competitors and not you. That is useful and it is not the same as fixing it. Ask directly what the outreach process is, who contacts publishers, and how many placements a typical month produces. If the answer is a dashboard, you are buying measurement. Both have a place, and our roundup of AI visibility tracking tools covers the measurement side.
Traditional link building chases high authority domains. Citation work is different, because what matters is whether a specific page is actually being pulled into answers for the queries your buyers ask. A DR 80 site nobody’s model reads is worth less than a DR 45 comparison page that ChatGPT quotes weekly. Ask how they identify target sources, and whether they can show you the specific pages currently feeding answers in your category.
Some firms pitch journalists and earn coverage. Some negotiate paid placements with publishers. Some do both, and a few are not clear about which. None of these is disqualifying, but they carry different costs, timelines and risks, and you should know which you are buying. Paid placements are faster and more predictable. Earned coverage is slower, harder and generally carries more weight. Ask for the split.
Being absent from a source is one problem. Being present and described inaccurately, or ranked last on a list your competitor sponsored, is a different and often more urgent one. Correction work requires a different kind of publisher relationship than new placement does. If existing coverage misrepresents your product, ask specifically whether the firm does refresh and correction work, and how often publishers agree to it.
Placement counts alone are a vanity metric. The useful report ties placements to changes in how models answer your target prompts, tracked over time across several assistants rather than one. Expect share of voice against named competitors, the prompts being tracked, and which specific sources are driving the answers. Ask to see a real client report with the names removed.
A data-study firm that lands national press is the right choice for a consumer brand and often the wrong one for a niche B2B tool nobody writes news stories about. For that tool, the answer is comparison pages, review platforms, community threads and category listicles. Match the firm’s mechanism to where your buyers’ questions actually get answered, not to the size of the logos on the agency’s homepage.
The common thread across all twelve is that they operate outside your website, which is exactly where the AI visibility problem actually lives. For unit-priced placements with transparent per-mention costs, Noble is the most direct option. For enterprise scale and high-authority targeting, uSERP and Impression are the strongest. For B2B SaaS specifically, MADX Digital and Embarque are built for it. And for brands that need original research to earn coverage nobody can buy, Fractl remains the specialist.
Whichever route you take, ask the mechanism question first. This category is young enough that the gap between firms doing real placement work and firms selling a dashboard with an outreach page attached is wide, and the marketing language on both sides is nearly identical.
