Best GEO tools in 2026: what a year of measurement costs

Generative engine optimization is not a campaign, it is a measurement you keep. The names an assistant gives change with the week, the wording and the engine, so a single reading tells you almost nothing and a year of readings tells you everything. That makes the pricing model, not the feature list, the first thing to compare.

This page puts the GEO tools side by side on what a year of measurement costs and covers, on facts each vendor publishes, read on 2026-08-18. Epovest is one of them, and the table is ordered by published entry price. The same tools are compared on AI visibility as a whole in our general comparison, and on the answer engines they cover in our guide to AEO tools.

How the money works in this category

Two models exist, and they behave differently over a year.

Subscriptions charge a fixed amount per month, whatever you measure. They suit a steady programme: the same prompts, the same engines, every week, forever. They are dead weight in the months where nothing is measured, and they cap what you may add without changing tier.

Prepaid usage charges per measurement. It suits a programme that breathes: a wide sweep before a launch, a narrow watch afterwards, a client audit that runs once. Epovest is the prepaid one here, at $0.10 per prompt, per engine, per survey, credits with no expiry and a $10 minimum top-up. Twenty prompts on six engines, weekly, is $48 a month; the same twenty prompts read once a month is $12.

Neither model is cheaper in the abstract. The question is whether your measurement is regular enough to fill a subscription.

The comparison

"Not specified" describes the vendor's public pages on the read date, and nothing about what the product does.

What GEO asks of a tool, beyond the price

A history you can still read next year. GEO results are a curve, not a number. A tool that keeps the answers keeps the curve auditable; one that keeps only the aggregate leaves you with a line you cannot defend.

A stable panel. Change the prompts and the curve breaks. Epovest treats a change of prompts, engines, rhythm or resolution as a new version of the series rather than a rewrite of the old one, so the break is visible instead of silent.

The sources behind the answers. Knowing you are absent is a start; knowing which twenty domains the engines lean on for your questions is what tells you where to go. That map is what the Atlas ranks, source by source, engine by engine, and it is not the same map twice: asked the same question on the same day, two engines share 6.4% of their sources.

Reachability by your own assistant. GEO work is repetitive and mostly reading. Several vendors ship an API and an MCP server; check the tier they sit in, because the difference between "included" and "enterprise" decides whether your assistant can do the reading for you.

What each tool is, per its own pages

Epovest asks your market's questions through the engines' official APIs, from daily to monthly, and archives every answer with its cited sources. No subscription: credits are debited only by the surveys that run. The REST API and MCP server ship with every account, and agencies run one project per client from a single prepaid balance.

Siftly, Keyword.com and AEO Vision hold the low entry prices, from a free tier to $9 per month, with the engine restrictions noted in the table.

Rankscale, Ayzeo, RankPrompt, LLM Pulse, AmICited, AI Clicks, Omnia and Mentionable sit between $20 and EUR 79 per month, several selling engines, projects or scans on top of the plan.

Dageno, Mint, Rankfender, Profound and Sight publish entry prices from $79 to $99 per month.

Scrunch, Athena, Cognizo and Evertune publish enterprise-facing prices from $250 to $800 per month.

Peec AI and Geneo did not publish an amount on the pages read.

Method

Selection: the platforms named or cited by ChatGPT, Claude, Gemini, Perplexity, Mistral and Grok on this market's buying questions, measured on our own panels, weekly, in English and French, every answer archived. No tool was added or removed by hand.

Facts: read on each vendor's public pricing and product pages on 2026-08-18. Base prices only; promotional discounts are ignored. The worked example above uses Epovest's published unit price and no other vendor's, because a subscription does not vary with the number of prompts.

Order: published entry price, ascending, at its nominal amount in the currency the vendor publishes. The page contains no score and no ranking.
