Semrush AI Visibility Is $99 Per Domain: The Agency Math, and the 2026 Alternatives

Semrush's AI visibility add-on costs $99 per month, per domain. For an in-house marketer tracking one brand, that is a defensible line item on top of an existing Semrush subscription. For an agency, the same pricing produces a very different invoice, because agencies do not have a domain — they have a roster.

This article does the math honestly, covers the cases where Semrush is still the right choice, and walks through the real alternatives in 2026, including the ones that are not us. All pricing below is from our published market research, compiled August 2026; verify current prices with each vendor before buying, because this category reprices often.

The per-domain math for agencies

Per-domain pricing is linear in your client count. Your revenue per client is not the issue — the issue is that your tooling cost scales at $99 for every client you add, before you have billed anyone for the work.

Retainer clients tracked	Semrush AI add-on cost	Per year
5	$495/mo	$5,940
10	$990/mo	$11,880
15	$1,485/mo	$17,820
20	$1,980/mo	$23,760

Take the 15-client agency, since that is roughly the midpoint of a typical small-agency roster. $1,485 per month is not a tool subscription; it is a part-time salary. If you bundle AI-visibility monitoring into existing retainers as a roughly $100–200/mo line item (your pricing will vary — that range is an example, not market data), the tooling consumes most or all of the monitoring revenue on every account. The service only works economically if you either charge substantially more per client or pay substantially less for tooling.

For comparison, the agency-tooling precedent in local SEO — BrightLocal and later AgencyAnalytics (the latter at roughly $79–239/mo for an entire client roster) — established the model this category has mostly not copied: flat multi-client pricing an agency can mark up. In AI visibility, per-domain and per-brand pricing is still the norm, which is exactly the complaint market reviewers keep raising.

When Semrush is still the right choice

An honest comparison starts here, because for some readers Semrush is the correct answer.

• You track one to three domains. At $99–297/mo the math is fine, and adding AI data inside a platform your team already lives in beats adopting a new tool.
• You are already paying for Semrush anyway. The add-on sits next to your rank tracking, backlink data, and site audits. One login, one invoice, one workflow. Consolidation has real value that a spreadsheet comparison undercounts.
• You need the SEO suite regardless. No AI-visibility point solution replaces Semrush's core toolkit. If the question is "Semrush plus its add-on for our two most important clients," rather than "AI monitoring for the whole roster," the add-on is a reasonable buy.

Reviewers' main criticism of the add-on — beyond pricing — is depth: it is a monitoring layer bolted onto a search platform, not a dedicated AEO product. Whether that matters depends on how far past "are we mentioned?" your service goes.

The alternatives in 2026

Verified pricing from our market research, with the honest fit for each:

Tool	Price	Built for	Trade-off for agencies
Otterly.AI	$25–160/mo	Solo marketers, SMBs	Single-brand oriented; monitoring only, no action layer
Rankscale	from €20/mo	SMBs on a budget	Minimal agency features
HubSpot AEO	~$45–50/mo	HubSpot users	Covers only 3 engines
Ahrefs Brand Radar	$199/mo add-on	Ahrefs users	Limited feature set
Peec AI	~€89–199/mo	Mid-market marketing teams	Not multi-client oriented; limited action layer
Profound	$99–$399+/mo	Enterprise / F500	Priced and designed for in-house teams

Otterly.AI ($25–160/mo)

The value pick for tracking a single brand. If you are a freelancer with one or two clients, or an in-house marketer at an SMB, Otterly's entry pricing is hard to argue with, and reviewers treat it as the accessible option in the category. The catch for agencies is structural: it is single-brand oriented and monitoring-only — you get the data, but no prioritized fix list and no multi-client reporting workflow. Fine at 2 clients; painful at 15.

Rankscale (from €20/mo)

The cheapest credible entry point in the category. Bootstrapped, lean, and priced accordingly. If your need is "a basic read on AI visibility for one brand, minimum spend," Rankscale clears that bar. Agency features are minimal, so treat it as a personal instrument rather than delivery infrastructure.

HubSpot AEO (~$45–50/mo)

If your clients run on HubSpot and you are already in that ecosystem daily, having AEO data appear inside the platform you use is convenient at a modest price. The trade-off is coverage: it tracks only three engines, so you are sampling a narrower slice of the answer landscape than tools covering ChatGPT, Claude, Perplexity, and Gemini together.

Ahrefs Brand Radar ($199/mo add-on)

The same consolidation argument as Semrush — it lives inside a toolkit your team may already use — at a flat add-on price rather than per-domain. Reviewers describe the feature set as limited relative to dedicated tools. If you are an Ahrefs shop with a handful of brands to watch, it is a reasonable bolt-on; as the backbone of a client-facing AEO service, it is thin.

Peec AI (~€89–199/mo)

Probably the strongest dedicated product in the mid-market bracket, and the right choice for an in-house marketing team at a funded mid-market company that wants serious measurement. For agencies the fit breaks down the same way it does across most of this list: it is not multi-client oriented, and the action layer — what to actually fix — is limited. You would be buying a good instrument and then building the agency workflow around it yourself.

Profound ($99–$399+/mo)

The enterprise reference product, backed by $155M in venture funding. If your client is a Fortune 500 brand with an in-house team that will act on the data, Profound is built for exactly that, and an agency serving one or two such clients might sensibly run it for them. It is not designed — or priced — for an agency spreading cost across 15 SMB retainers.

What agencies are actually shopping for

You will still find comparisons claiming that no tool in this category markets white-label reporting to agencies. That was arguably true in late 2025. It is not true now, and we would rather say so than sell against a gap that closed.

Purpose-built agency products shipped through the first half of 2026: AgencyScope ($49/mo for 5 client brands, $249 for 50), Geneo's agency tier ($129 for 5 seats, $249 for 15), Mentionable (€299/mo, unlimited projects), Rank Prompt (roughly $119/mo for 500 brands), Routeless Radar ($499/mo for 3 workspaces), Am I on AI ($250/mo for 3 clients). By July 2026, category roundups were describing white-label as a standard offering rather than a differentiator. Treat any "nobody serves agencies" line — including ones we published earlier this month — as out of date.

So the honest framing is not that nobody does this. It is that an agency is buying four things at once, and most tools deliver two:

1. Multi-client pricing that does not scale linearly with roster size. Per-domain pricing feels fine at 3 clients and becomes the largest line in your software budget at 20.
2. Reports a client can receive under the agency's own brand. Now widely available. Check whether it covers the live share link and the emails, or only the PDF.
3. Every engine included, not sold per-engine. This is where quoted prices drift from real ones: Ayzeo charges $29/mo per additional engine, Otterly's engine add-ons run $9–$439, and Semrush's $99 is per domain before any of it.
4. Evidence under the score. "Your client's visibility is 61" is not something you can defend on a call. You need the dated answers each engine actually gave and the sources they cited.

Here is the one plug, with the math and the trade-offs attached. MentionScope is $99/mo flat for 15 clients — the roster that costs $1,485/mo on Semrush's per-domain pricing — with weekly scans across ChatGPT, Claude, Perplexity, and Gemini on every tier with no per-engine add-ons, competitor share of voice, client-branded reports, a prioritized fix list per client, and an answers explorer that shows the raw dated responses behind every score. Solo is $49/mo for 5 clients; Scale is $199/mo for 40.

Two caveats you should weigh: we are the newest entrant on this list, and on headline price alone AgencyScope matches our entry tier and Rank Prompt undercuts everyone at high brand counts. If you want to check our numbers before trusting them, the free AI Visibility Checker scans one domain instantly.

How to decide

• 1–3 brands, already on Semrush or Ahrefs: buy the add-on you already half-own. Consolidation wins at small scale.
• One brand, minimum budget: Rankscale or Otterly.
• HubSpot-native client base: HubSpot AEO, if three engines is acceptable coverage.
• In-house mid-market team: Peec.
• Enterprise client with an in-house team: Profound.
• Agency with 5+ retainer clients who need branded reports: shortlist on the four criteria above rather than on white-label alone, since most agency-tier tools now have it. Price the whole roster, count which engines are included versus billed as add-ons, and ask to see the raw answers behind one score before you commit.

Whatever you pick, model the cost at your roster size in 18 months, not today. Per-domain pricing feels fine at 3 clients and becomes the largest line in your software budget at 20.

FAQ

How much does Semrush AI visibility cost for an agency?

The Semrush AI add-on is $99 per month per domain. An agency tracking 15 client domains pays $1,485 per month ($17,820 per year); 20 domains costs $1,980 per month. There is no flat multi-client tier.

What is the cheapest AI visibility tool in 2026?

Rankscale starts from about €20/mo and Otterly.AI starts at $25/mo, both aimed at single-brand use. HubSpot's AEO features run roughly $45–50/mo but cover only three engines. Note that the cheapest tools are single-brand instruments; multi-client agency use is priced differently across the category.

Is the Semrush AI add-on worth it?

For an existing Semrush customer tracking one to three domains, generally yes — the consolidation into an existing workflow justifies $99/mo per domain. For agencies with larger rosters, the per-domain pricing scales linearly with client count and usually breaks the economics of a monitoring retainer.

What should agencies look for in a Semrush alternative?

Three things most AI-visibility tools lack, per 2026 category reviews: flat multi-client pricing rather than per-domain fees, white-label reports deliverable under the agency's own brand, and a prioritized action layer — schema, llms.txt, reviews, citations, entity presence, content gaps — that converts monitoring into billable work.
