GEO Agency or Software? How to Choose in 2026

Every team that starts caring about ChatGPT and Perplexity citations hits the same fork: buy a piece of software and measure it yourself, or hire an agency to do the strategy and execution for you. Our index carries both — 14 GEO & AEO agencies charging real retainers, and a dozen-plus self-serve visibility platforms and rank trackers with published monthly pricing. This guide puts the two purchase models side by side, using nothing but our own gate-passed listing data, so you can see which one actually fits before you talk to a sales rep.

The quick answer

Software and agencies solve different problems, and the price gap tells you which one you’re buying:

• You need to measure whether you’re cited, on a budget, starting this week → software. Otterly AI starts at $29/month; Nightwatch at €79/month; Morningscore at $69/month. None of them will change what gets published on your site.
• You need someone to do the work — content, technical fixes, a strategy — and don’t have the in-house team to execute it → an agency. Every one of our 14 listed GEO/AEO agencies is a service, not a dashboard; the cheapest published floor is AEO Engine’s $1,597/month Growth tier, and most quote custom enterprise retainers with no public number at all.
• You need both → most mid-market and enterprise programs end up running a platform for measurement AND an agency (or in-house team) for execution — the tools don’t produce content or fix pages, and an agency without a measurement layer is flying blind on results.

Software vs agency, at a glance

	Self-serve software	GEO/AEO agency
What you get	Automated tracking of mentions/citations across AI engines, dashboards, alerts	Strategy, content production, technical fixes, reporting — a team doing the work
Typical entry price	$29–$300/month	$1,597–$24,000+/month (published tiers), or custom enterprise retainer
Time to first signal	Minutes to days (connect prompts, start tracking)	Weeks to months (onboarding, content/technical work has to ship and get crawled first)
Who runs it	Your own team	The agency’s team, sometimes alongside your own
Does it change your AI visibility?	No — it measures it	Yes — that’s the entire service
Best first step for	A team that already writes/optimizes its own content and just needs the scoreboard	A team with budget but no bandwidth or expertise to execute GEO itself

What software actually gets you

The self-serve platforms in our index are measurement tools, full stop — none of them touches your website or writes your content. What differs between them is engine coverage and depth. Otterly AI is the cheapest credible entry point at $29/month (Lite), tracking ChatGPT, Perplexity, Google AI Overviews and Microsoft Copilot on a schedule. Peec AI starts at €85/month and adds a citation-source view — which domains and pages the engines actually cite for a topic — that doubles as a target list for whatever content work you do next. Scrunch AI ($250/month Starter) and Profound ($99–399/month) sit at the higher end of self-serve, built for agencies managing multiple client accounts or brand teams needing query-volume depth.

Two listings in our index are narrower and cheaper still because they’re rank trackers first, AI-visibility trackers second: Nightwatch (€79–399/month) layers ChatGPT/Claude/Gemini/Perplexity/Copilot prompt tracking on top of a full traditional Google/Bing rank-tracking product, and Morningscore ($69–299/month) does the same with a gamified SEO-task checklist attached. If your actual job is “watch our existing rankings and also see if we show up in AI answers,” these two are more directly built for that than a pure AI-visibility platform is.

None of this software writes a page, fixes a schema error, or gets you mentioned anywhere. It tells you, with a number, whether what you’re already doing is working.

What an agency actually gets you

The 14 agencies in our GEO & AEO agencies comparison sell the opposite: they do the work, and most don’t publish a rate card. AEO Engine is the cheapest to price without a sales call — a free, no-signup GEO audit tool backed by a managed content-and-citation service on a published $1,597/month (Growth) or $2,997/month (Scale) 90-day contract. Digital Elevator runs a productized sprint/program/campaign structure from $3,000 to $24,000+/month with defined scope, and Percepture publishes a four-tier rate card from $3,500 to $10,000+/month. Omniscient Digital publishes a floor (“from $10,000/month”) for GEO folded into a full organic-growth program tied to pipeline. Everyone else — Growleads, 5W Public Relations, BrightEdge, iPullRank, OMNIUS, Minuttia, First Page Sage, Siege Media, RankZero and Go Fish Digital — quotes a custom enterprise retainer (RankZero backs its with a written 25%+ AI-traffic-lift guarantee in 90 days; Go Fish Digital’s only public entry point is a “Request Proposal” contact form) with no public number, which itself is a signal: these are built for teams with real budget, not a self-serve trial.

What you’re actually buying differs by agency even within “GEO agency.” First Page Sage publishes an unusually concrete six-element methodology (lists, databases, authority, reviews, achievements, sentiment) rather than a vague pitch. Siege Media and Omniscient Digital run GEO inside a broader content-and-digital-PR engine — you’re paying for durable citations as a byproduct of genuinely good content, not a GEO checklist run in isolation. Percepture and iPullRank lead with measurement-first, technical-SEO-native positioning and named enterprise case studies. None of this is interchangeable, and picking “an agency” without reading what each one specifically does is the single easiest way to overpay for the wrong service.

Choose X if / avoid X if

• Choose software if you (or your team) already write and ship your own content and technical fixes, and the gap is simply not knowing whether it’s working in AI answers yet. Avoid it if you have no plan for acting on what the dashboard tells you — a scoreboard with no player on the field doesn’t move the needle.
• Choose an agency if you have budget but not the in-house GEO expertise or bandwidth, and you want someone accountable for the outcome, not just the measurement. Avoid it if your budget is under $1,597/month — only AEO Engine publishes a tier that low, Digital Elevator’s next-cheapest published floor starts at $3,000/month, and every other listed agency here is priced for a real program, not a trial.
• Choose both if you’re running (or about to run) a real GEO program: the agency does the work, and a platform like Otterly AI or Peec AI gives you an independent number to check the agency’s own reporting against — a pattern several of our listed agencies (Percepture, Siege Media) explicitly build their own client reporting around.

Methodology & sources

Every price, pricing model and positioning claim above comes from CitedIndex’s own quality-gated listings — each independently researched, sourced and dated: Otterly AI, Peec AI, Scrunch AI, Profound, Nightwatch, Morningscore, and all 14 agencies in the GEO & AEO agencies comparison (verified 2026-07-13 through 2026-07-27, per each listing’s own last-verified date). First Page Sage’s six-element methodology is sourced directly to the firm’s own GEO services page. Where an agency’s pricing isn’t published, we say so explicitly rather than estimate a number — “custom enterprise” here always means the agency itself declines to publish a rate, not that we couldn’t find one.
