Semrush AI Visibility vs Fortitude Media: 2026 comparison

Last checked: 10 June 2026. Methodology: facts verified against Semrush's public pricing pages and our own published pricing on that date. Read our full methodology.

The short answer#

If your team already lives in Semrush and has SEO skills in-house, the Semrush AI Visibility Toolkit at $99 per month per domain, or Semrush One from $199 per month, is excellent value, and we say that as a competitor. Fortitude Media is a dedicated AI visibility company rather than a module inside an SEO suite. We track five engines including Claude, we hand over up to twelve months of your category's history on day one, and when the tracking shows a problem, our Forge service does the work and is accountable to the same chart. In short: Semrush is built for the SEO practitioner who will act on the data themselves. Fortitude is built for the founder or managing director who has no SEO team and needs the measuring and the fixing under one roof.

What is the Semrush AI Visibility Toolkit?#

The Semrush AI Visibility Toolkit is the AI search tracking module inside Semrush, one of the largest SEO platforms in the world. Semrush is a public company (NYSE: SEMR) with 2025 revenue of $443.6 million, up 18% year on year, and annual recurring revenue of $471.4 million. This is not a startup that might vanish next quarter. It is an established suite that millions of marketers already use for keyword research, rank tracking and site audits, and the AI visibility features slot into that existing workflow.

Semrush sells its AI visibility capability in several forms, per its AI pricing page:

• AI Visibility Toolkit at $99 per month per domain.
• Semrush One Starter at $199 per month (50 prompts, 500 keywords).
• Semrush One Pro+ at $299 per month (100 prompts, historical data).
• Semrush One Advanced at $549 per month (200 prompts, share of voice, API access).
• Enterprise AIO on custom pricing.

Semrush also publishes a free public AI Visibility Index with industry award winners, which is worth a look whatever you end up buying.

One practical note: AI engine coverage in this market changes often, and Semrush's tracked engine list has not centred on Claude in its core tracking claims as of our last check. Before you buy, verify the current engine list on Semrush's own pricing page rather than relying on this page, a review, or anyone's marketing.

Semrush vs Fortitude Media: side by side#

What Semrush does well#

Semrush deserves its position as the value benchmark in AI visibility tracking, and three things stand out.

Price. At $99 per month per domain for the AI Visibility Toolkit, or $199 per month for Semrush One Starter with 50 prompts and 500 keywords, Semrush has set the bar for what self-serve AI tracking should cost. If price per feature is your only axis, Semrush is hard to argue with, and we are not going to try.

Distribution and bundling. Most teams considering Semrush already pay for Semrush. Adding AI visibility to a suite your team opens every morning means no new logins, no new vendor, no new training. That convenience is real value, not a gimmick.

A public index and a public company behind it. Semrush publishes a free AI Visibility Index, and the company reports its numbers to the stock market every quarter. You know exactly who you are buying from and that they will still exist in three years.

If you have an in-house SEO team that knows how to turn tracking data into briefs, content and technical fixes, the Semrush AI Visibility Toolkit may be all you need. We would rather tell you that plainly than pretend otherwise.

Where Fortitude is different#

The differences are not about feature counts. They are about what kind of company you are buying from and what happens after the dashboard shows you a problem.

We are a dedicated AI visibility company, not a module. Fortitude Media exists to make B2B companies the brands AI recommends. Fortitude Sentinel, our platform, sees where you stand. Fortitude Forge, our managed service, changes it. AI visibility is not a tab in a larger product; it is the whole product.

We track Claude, and we name all five engines. Sentinel tracks ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews on every tier. Claude matters in B2B because buyers researching considered purchases use it. As noted above, check Semrush's current engine list yourself before you decide; it changes, and we would rather you verify than take our word for a competitor's coverage.

You start with history, not a blank chart. The Registry is our longitudinal record of how AI engines answer canonical buyer-intent prompts in each category, built from our own runs on our own prompt library (the same model Ahrefs and SimilarWeb use; we never sell customer prompts or account data). New customers get up to twelve months of their category's history at signup, with the deepest coverage in UK B2B categories today. With most tools, including Semrush One's historical data, the record starts the day you subscribe.

When the chart shows a problem, someone does the work. Semrush hands you data and leaves the doing to your team. Forge plans (£3,950 to £11,950+ per month, each including Sentinel Pro) deliver content, digital PR and website work on the Fortitude Framework, at roughly half the cost of the equivalent in-house team, which we estimate at £165k to £255k per year. The same company that measures your AI visibility does the work and is accountable to the same chart. We have not found another UK provider that combines a tracking platform and a managed delivery service on one continuous ladder from free to full service.

Different buyer, different design. Semrush is built for people whose job title contains "SEO". Fortitude is built for the founder or MD of a UK B2B firm who has no SEO team, no time to learn one more dashboard, and a sales pipeline that is quietly being shaped by what AI engines say about them. If you are weighing up whether you need a tool, an agency or both, our guide to tools, agencies or both covers that decision in detail.

Choose Semrush if... / Choose Fortitude if...#

Choose Semrush if:

• Your team already pays for Semrush and uses it weekly. The AI Visibility Toolkit at $99 per month per domain is the obvious add-on.
• You have SEO skills in-house and only need data, not delivery.
• You manage many domains and want per-domain pricing inside one familiar suite.
• Your budget for AI visibility is firmly under $100 a month and you can act on the findings yourself.

Choose Fortitude if:

• You are a UK B2B founder or MD with no SEO team and you need both the measurement and the work done.
• Claude coverage matters to you and you want it confirmed on every tier, not subject to a changing engine list.
• You want up to twelve months of your category's history on day one rather than starting from zero.
• You want one ladder from a free check to a full managed service, with no jump to a second vendor when the score needs to move.

Frequently asked questions#

Is the Semrush AI Visibility Toolkit worth it?#

Yes, if your team already uses Semrush and has SEO skills in-house. At $99 per month per domain it is the value benchmark for self-serve AI visibility tracking, and Semrush One bundles from $199 per month add prompt tracking at a fair price. It is software only, so plan for your own team to act on what it finds.

Does Semrush track Claude?#

Semrush's core tracking claims did not centre on Claude at our last check on 10 June 2026, but engine lists in this market change often, so verify the current list on Semrush's own pricing page before buying. Fortitude Sentinel tracks five engines including Claude on every tier.

What is the difference between the AI Visibility Toolkit and Semrush One?#

The AI Visibility Toolkit is $99 per month per domain. Semrush One is a bundled plan: Starter at $199 per month includes 50 prompts and 500 keywords, Pro+ at $299 adds historical data with 100 prompts, and Advanced at $549 includes 200 prompts, share of voice and API access. Enterprise AIO is priced on a custom basis.

How much does Fortitude Media cost compared with Semrush?#

Fortitude starts free: a Free AI Visibility Check, then Sentinel Free with one brand, five prompts and a monthly refresh. Paid tiers are Sentinel Basic at £199 per month, Standard at £499 and Pro at £999, then Forge managed plans from £3,950 to £11,950+ per month. Semrush starts at $99 per month per domain, so Semrush is cheaper at entry level and we do not claim otherwise.

Can Semrush do the AI optimisation work for me?#

No. Semrush is software: it shows you the data and your team does the work. If you need the work done as well as measured, Fortitude Forge delivers content, digital PR and website work from £3,950 per month, measured in the same Sentinel platform.

See where you stand first#

Before you choose either of us, find out whether AI engines recommend you at all. Our Free AI Visibility Check shows how ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews answer when buyers ask about your category. No card, no sales call, and if Semrush turns out to be the better fit for you, we would rather you knew that early.
