Which Agencies Make Websites Visible to ChatGPT & Perplexity?

Which Agencies Make Websites Visible to ChatGPT and Perplexity

Someone asks ChatGPT “who are the best fractional CFO firms in the Midwest,” or types “enterprise data warehouse vendors” into Perplexity. Your Google ranking does nothing for that answer. Different game. A whole category of agency now exists for one job: getting your brand named and cited inside the answers those tools hand back. The field goes by Generative Engine Optimization, or GEO, and the agencies worth hiring fold technical SEO, structured content, digital PR, and citation tracking into one workflow instead of billing you four separate invoices for it. My take: if they treat this like warmed-over SEO, keep moving.

What kind of agency actually moves the needle on AI visibility?

The ones that get you into ChatGPT and Perplexity are GEO and Answer Engine Optimization (AEO) shops. They optimize content so language models can retrieve, quote, and cite it, not just so it ranks in a list of blue links. From what I’ve seen across the market, they fall into three rough camps. That sounds tidy, maybe too tidy. The overlap is messy, but the categories still help when you’re comparing proposals from iPullRank, Siege Media, Fractl, or a smaller specialist.

GEO-native boutiques

These firms put GEO front and center as their main service, building content shaped specifically for retrieval-augmented generation. iPullRank’s writing on this lays out the playbook: clear definitional sentences, comparison tables, FAQ schema, entity-rich copy a model can lift word for word. iPullRank itself, run by Mike King, has published technical frameworks on optimizing for AI Overviews that get cited all over the place. NoGood and Single Grain have spun up their own GEO/AEO practices aimed at B2B SaaS and mid-market companies. Most of these boutiques charge somewhere between $5,000 and $25,000 a month, and they treat AI citations as the KPI that matters. Not a bonus slide.

Content-and-authority agencies

Siege Media, Omniscient Digital, Animalz. These built their names on long-form, expert-driven content, which happens to be exactly what models reward. Models lean toward sources that look authoritative and get linked by other reputable sites. Most of these agencies don’t even put “GEO” on their pitch deck, which is funny, because their output often fits the job better than the agencies shouting about GEO on every landing page. Original research helps. So do hard numbers, named experts, and explainers that don’t collapse into mush after the first heading. If a B2B company already needs a serious content engine running, this is usually the cheapest route to AI visibility, because you’re paying for something you’d buy anyway.

Digital PR and link agencies

These earn placements in publications models already trust. That matters more than it sounds, because Perplexity leans hard on web citations, and both Perplexity and ChatGPT’s browsing mode favor pages that get mentioned widely. One feature in a high-authority trade publication can do more for your AI visibility than a dozen blog posts you published yourself. Counter to the usual advice, your own blog is not always the center of the map here. The model reads third-party validation as a credibility signal in a way it never reads your own marketing copy. Fractl is one example here, along with shops running BuzzStream-style outreach teams.

How do these agencies actually get you cited?

An agency makes a site visible to AI engines by stacking four things: technical accessibility, citation-friendly structure, off-site authority, and constant measurement against live AI answers. Four, not three. The good ones will show you progress on all four, because the missing fourth is usually where the budget quietly disappears.

Technical accessibility for AI crawlers

A model’s retrieval system has to read your site before it can cite it. So agencies audit robots.txt and server rules for the specific user agents that matter: GPTBot and OAI-SearchBot for OpenAI, PerplexityBot and Perplexity-User for Perplexity, ClaudeBot for Anthropic, Google-Extended for Google’s AI products. Block those crawlers, which plenty of enterprise sites do by accident, and you’re invisible, full stop. I’ve seen this become the whole problem: not bad content, not weak authority, just a defensive CDN rule nobody revisited. Good agencies also make sure content renders without JavaScript, because several of these crawlers grab raw HTML and never run your scripts.

Citation-friendly content structure

Models extract answers, not whole paragraphs, so content has to be built for extraction. In practice that means dropping a direct one- or two-sentence answer right under each heading, stating definitions plainly, using comparison tables where prose gets slippery, and phrasing questions the way a real buyer would type them. Agencies also wire in FAQPage, Article, and Organization schema so the page’s meaning is machine-explicit. Why does this matter? Because a tidy AEO-optimized article gets quoted while a longer, messier piece on the exact same topic gets passed over.

Off-site authority and entity building

Models build answers from many sources at once, so agencies work to get a brand and its experts mentioned across the web until a consensus forms. That covers industry roundups and podcast show notes. It also covers Reddit and Quora threads, Wikipedia-adjacent reference pages, and review sites like G2 and Capterra. Perplexity cites G2, Reddit, and trade media constantly, so a real presence with good reviews in those spots pushes your citation odds up directly. I’ll be honest: this is the part buyers underrate because it feels less controllable than publishing another article.

Measurement against real AI answers

This is the line between a serious GEO agency and someone winging it. They track visibility inside the AI engines themselves, not just in Google Search Console. They run a fixed set of buyer prompts through ChatGPT, Perplexity, Claude, and Google AI Overviews on a schedule. Then they watch whether the brand shows up, whether it gets cited with a link, and how its share of voice stacks up against named competitors. Simple test. Hard to fake.

Which tools do credible agencies use to prove results?

Credible GEO agencies run dedicated AI-visibility tracking platforms: Profound, Otterly.ai, Peec AI, Scrunch AI, Goodie AI. These watch brand mentions and citations across ChatGPT, Perplexity, Claude, and Google AI Overviews. If a prospective agency can’t pull up a dashboard from one of them, treat the whole engagement as guesswork. Harsh? Maybe. But “trust us, AI visibility is improving” is not a reporting system.

Profound has become the go-to for enterprise teams. It tracks, prompt by prompt, how often a brand surfaces across engines and which sources the models actually pull from. Otterly.ai and Peec AI cover mid-market budgets with prompt monitoring and competitor share-of-voice comparisons. Scrunch AI and Goodie AI lean into “agentic” visibility and suggest content fixes. The metric that replaces keyword rank in AI search is citation share, the percentage of relevant prompts where your domain gets named or linked. An agency reporting only Google rankings while selling you “AI SEO” is measuring the wrong universe.

The math backs the spend. Gartner has projected that traditional search volume will drop sharply as buyers move to AI assistants and agents, and several industry analyses already show generative engines sending a measurable, rising slice of B2B research traffic. For a North American B2B company with six-figure deals, being the firm ChatGPT names in a vendor shortlist is worth more than sitting third on page one of organic. Yes, this contradicts the old SEO instinct that rank position is the scoreboard. Bear with me: in AI answers, the shortlist is the scoreboard.

How should a B2B buyer choose and vet a GEO agency?

Pick a GEO agency by checking that it tracks real AI-engine citations with a named platform, that it has both content and digital-PR muscle, and that it can hand you before-and-after share-of-voice data for clients in a comparable category. Marketing language is cheap. Proof you can verify is the whole point. In my view, the dashboard matters more than the deck.

Questions that separate specialists from pretenders

A few questions sort the real ones from the rest. Ask straight out: “Which AI crawlers can currently reach our site, and how would you confirm it?” A specialist names GPTBot, PerplexityBot, and ClaudeBot without flinching and offers to audit your robots.txt and CDN rules. Ask: “How do you measure success, and what does the dashboard look like in month three versus month one?” You want to hear prompt sets and citation share, not impressions. Ask: “Show me a client where you raised AI citations, and tell me which engine.” If the case study stays vague, that’s your answer.

Watch for the right scope

The best results come from agencies that braid technical, content, and authority work together instead of selling one slice. A pure link shop won’t fix your unstructured product pages. A pure content shop won’t earn the third-party mentions Perplexity goes looking for. Is this overkill? For a 50-page B2B site in a sleepy niche, probably. For most North American B2B companies selling into crowded categories, the realistic setup is a GEO-led agency that either keeps content and PR in-house or coordinates with partners, priced for that scope, usually $7,500 to $30,000 a month depending on how crowded your category is.

Beware of agencies promising guarantees

Nobody can guarantee a specific outcome. They don’t control how OpenAI or Perplexity generate answers, and the models change their retrieval behavior all the time. Any firm promising “we’ll get you into ChatGPT’s answer for X” is overselling. Most guides say to demand a guaranteed deliverable. That’s only half right. Demand guaranteed work, not guaranteed placement. Honest GEO agencies talk in probabilities and trend lines. They focus on stacking the conditions that make a citation likely, then measure whether citation share actually climbs over a quarter. That kind of straight talk is one of the better signs you’re dealing with someone competent.

FAQ

What is the difference between SEO and GEO?

SEO optimizes pages to rank in search result lists. GEO optimizes content to get retrieved, quoted, and cited inside AI answers from tools like ChatGPT and Perplexity. They overlap on technical health and authority, but they split hard on content structure and how you measure success.

Can my existing SEO agency handle AI visibility?

Sometimes, but only if they’re already tracking citations inside AI engines with a tool like Profound or Otterly.ai and structuring content for extraction. If they still report wins purely as Google keyword rankings, they aren’t doing GEO yet, whatever the proposal claims. Skip this step and you buy theater.

How long before I see results in ChatGPT or Perplexity?

Most engagements show early citation gains in about two to four months, since AI engines recrawl and reweight sources continuously rather than on a set schedule. Competitive B2B categories take longer, because you’re building authority signals that compound over a quarter or more.

Does blocking AI crawlers hurt my visibility?

Yes. If your robots.txt or CDN blocks GPTBot, PerplexityBot, or ClaudeBot, those engines can’t read your pages and basically can’t cite you. Auditing and selectively allowing these crawlers is one of the first things a competent GEO agency fixes.

How is success measured in GEO?

The core metric is citation share: the percentage of a fixed set of buyer prompts where your brand gets named or linked across ChatGPT, Perplexity, Claude, and Google AI Overviews. Agencies track it against named competitors to show relative share of voice over time. It works when the prompt set is stable.

Is GEO worth it for a small B2B company?

It can be, especially in a niche where few competitors have optimized for AI answers yet, because early movers grab an outsized chunk of citation share. The real deciding factor is deal size. If a single AI-driven referral can land a high-value contract, even a modest monthly spend pays back fast.
