GEO agency vs self-serve tool: which should you choose?

There is no single winner. A GEO agency sells execution and off-site relationships: content, digital PR, and the earned media that most AI citations come from. A self-serve tool sells measurement and control for a fraction of the price. The deciding question is whether someone on your team can own the work every week for months, not which option looks cheaper.

Disclosure: BeCited is our product, and it is a self-serve tool, so we have a side in this. We kept every price and competitor claim to public, checkable facts, and where a number came from a company that sells the thing it measures, we say so.

The "agency or tool" question shows up the moment a team decides AI search visibility is worth real budget. It usually gets answered badly, because both sides are sold by people with an interest in the answer. Agencies publish "why you need an agency" guides; tool vendors publish "do it yourself" ones. This piece lays out what each actually buys you, what it costs from public pricing, and the one factor that settles most decisions.

Why is choosing between them suddenly a real decision?

Because AI answers now sit between buyers and your site, and being absent from them costs pipeline. Forrester found 94% of business buyers use AI somewhere in their buying process, up from 89% a year earlier. When an assistant names two or three vendors instead of ten links, being left out is expensive, and closing that gap needs a tool, an agency, or both.

The shift is not hypothetical. Forrester's 2025 Buyers' Journey Survey put AI usage among business buyers at 94%, a five-point jump in a year (Forrester). And the answers are replacing clicks, not just adding to them: Pew Research, tracking real browsing rather than a survey, found people clicked a traditional search result in just 8% of visits when an AI summary appeared, against 15% when it did not (Pew Research). Fewer visits reach your site, and more of the buying decision gets shaped inside the answer box first. That is why AI visibility became a line item, and why the choice of how to work on it is worth getting right instead of guessing.

What does a GEO agency actually do?

A GEO agency runs the work for you: it audits your AI visibility, fixes the technical and content gaps, then builds the off-site presence AI answers pull from. That last part, digital PR and earned media, is where an agency earns its fee, because it needs outreach and relationships a dashboard cannot do on its own.

The reason off-site work justifies the price is in the citation data. Muck Rack, which sells PR software and so has a reason to emphasize this, analyzed more than 25 million links from ChatGPT, Claude, and Gemini answers and found earned media accounted for 84% of all AI citations, journalism for 27%, and paid or advertorial content for just 0.3% (Muck Rack). Getting mentioned in the kind of third-party coverage an AI trusts is closer to PR than to publishing another blog post, and PR is what a good agency actually sells.

The price reflects that it is done-for-you labor. WebFX, itself an agency, publishes a rate card that reads as representative of the market: GEO retainers from $1,500 to $50,000 or more per month, with its own service starting at $3,000 a month and project work between $5,000 and $50,000 (WebFX). At the low end you are often buying repackaged SEO, since real multi-engine tracking and outreach cost the agency enough that a sub-$2,000 "GEO retainer" rarely includes much of either.

What does a self-serve GEO tool do?

It measures. A tool runs the prompts your buyers would ask across ChatGPT, Perplexity, Google AI Overviews, and others, then reports where you are mentioned or cited. The stronger ones add fixes and re-measure. What almost none of them do is the off-site outreach, so a tool shows you where you stand, and in the better cases what to change, but you still do the changing.

Entry pricing sits one or two orders of magnitude below an agency retainer. These are the current published monthly prices, each from the vendor's own pricing page:

Sources, in order: Otterly, Profound, Semrush, Ahrefs. Two honest notes sit under that table. Engine coverage at the entry tier varies widely: Profound's $99 plan tracks ChatGPT alone, while Otterly's $29 plan tracks four engines, so the sticker price is not the whole comparison. And most tools here monitor; a smaller set closes the loop by re-measuring after a fix. We pulled that distinction apart in AI visibility tools compared, and sorted the category for B2B teams in best GEO tools for B2B SaaS.

How do the costs really compare?

A self-serve tool runs from about $29 to a few hundred dollars a month. An agency retainer starts near $1,500 and climbs past $50,000. But the tool price is not the true cost, because a tool hands you findings, not finished work. The real comparison is tool-plus-your-time against agency-does-it-all, and that turns on how much time your team actually has.

WebFX's same rate card puts DIY tools and tracking software at $10 to $1,000 or more per month, against agency retainers many times higher (WebFX). The gap is labor. A tool that flags a missing schema block or a page AI crawlers cannot read has named the problem; someone still has to write the schema, fix the rendering, and pitch the story that earns the citation. Teams that have run GEO in-house tend to describe it as a few hours of analysis and execution every week, indefinitely, which is cheap if you have those hours and expensive if you do not.

Which parts of GEO can a tool handle, and which need a person?

Tools are good at the on-page half: finding pages AI crawlers cannot reach, flagging missing schema, tracking which prompts cite you. They are weak at the off-page half, the digital PR and third-party coverage that drives most citations, because that is relationship work. Roughly, a tool covers what lives on your own domain, and a person covers what lives everywhere else.

The off-page half is where the citations actually come from, and it shows up in the numbers. Stacker and Scrunch, two vendors in the distribution and monitoring business and so an interested source, tested identical articles and found brand-owned content on a company blog was cited in 7.6% of relevant AI answers, while the same content republished across third-party news outlets reached about 34%, a 325% lift (Stacker). The sample was small, 8 articles across 5 AI platforms, so read it as directional, but the direction matches the wider citation data: where the content sits matters as much as what it says.

The on-page half is real work too, and it is the part a tool does speed up. Otterly's study of more than a million citations found 73% of sites carry technical barriers that block AI crawler access (Otterly), the kind of concrete, fixable issue a scan surfaces in minutes and a person then repairs. That is the honest division of labor: a tool for the diagnosis and the on-domain fixes, and a separate decision about who does the off-domain outreach, since no tool does that for you. The specific on-page moves that raise citation odds are in how to get cited by ChatGPT.

So when should you hire an agency, and when is a tool enough?

Hire an agency when you have budget but no one who can own GEO week after week, or when the job leans heavily on digital PR and earned media. Use a tool when you have someone in-house with a few hours a week and the skill to act on what it finds. The deciding factor is internal ownership, not budget.

Most teams get this backwards by starting from price. The better starting question is whether a specific person will own the topic for the next six months, because GEO is not a one-time fix. Fractl, a marketing research firm rather than a tool vendor and so a cleaner read, found in its Q2 2026 study that only 12% of marketers are very confident they can measure results from their AI-search work, even as 49% now monitor it, up from 22% a year earlier (Fractl). Plenty of teams are watching; few are sure the work is paying off. A tool closes the measurement gap cheaply. It does not close the execution gap. If no one will do the execution, the retainer is buying you the doer, and that is worth the premium. If you already have the doer, the tool is buying them sight.

So which should you start with?

Start with measurement, whichever path you pick. You cannot judge an agency's work, or your own, without a dated before-and-after, so a tool that scores where you stand today pays for itself either way. If the fixes then need PR muscle you lack, add an agency for that part. Buy for the job in front of you, not the label.

The one thing both paths need is proof. An agency that cannot show you a dated before-and-after is selling activity, not results, and an in-house effort with no baseline is guessing. That is the bar we built BeCited to clear: a free report that scores your AI visibility and search health today, with anything estimated labeled as estimated rather than dressed up as measured, so the next re-audit shows real movement instead of noise. Nothing in it is a guarantee of a citation. It is a measurement of where you stand and what changed since last time. The scoring is public on the methodology page, you can run the free report, and the rest of what we have learned about this shift is on the blog.
