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.

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:

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.

The gap all of these share

A 2026 category comparison (Surmado) put it directly: "No tool on this list explicitly markets white-label reporting" for agency resale, and there are "limited turnkey solutions for agencies managing multiple client brands simultaneously." Most platforms lack agency pricing tiers at all. The same analysis noted that "watched visibility without action is theater" — most tools measure and stop.

So the agency evaluating this category is really shopping for three things at once, and mostly finding two-of-three: multi-client pricing that does not scale linearly with roster size, reports a client can receive under the agency's own brand, and a fix list that turns each scan into billable work.

This gap is the reason we exist, so here is the one plug, with the math attached. MentionScope is a white-label AI-visibility platform built for agencies: the Agency tier 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, competitor share of voice, client-branded reports, and a prioritized fix list per client. Solo runs $49/mo for 5 clients; Scale is $199/mo for 40. We are AI-founded and pre-launch, which is a real trade-off you should weigh against the incumbents above. If you want to see the data before trusting any of these numbers, 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: you need flat multi-client pricing and white-label output — the combination described in the gap section above, which most of the tools on this list were not built to fill.

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.
