MarketMuse
Built on a patented topic-modeling engine since 2013, then quietly stopped listing dollar prices in 2024, the same year a Danish accessibility company bought it.
What is MarketMuse?
MarketMuse launched in 2013, founded by Aki Balogh and joined early by Jeff Coyle, built around a patented topic-modeling engine (U.S. Patent 10,409,875) that returns roughly 50 semantically related topics for a given query, ranked by relevance rather than listed as keyword variants. Its signature metric, Personalized Difficulty, adjusts keyword difficulty based on a site's own existing topic authority instead of a generic industry-wide score, which is the kind of detail that separates it from lighter keyword tools. Later acquisitions — Grepwords for its keyword database — and a shift toward LLM-agnostic content generation pushed the platform from a research tool into what it now calls a full content command center, covering research, briefs, optimization, and strategy documents in one place.
The bigger change happened outside the product. Siteimprove, a Danish digital-accessibility and web-governance platform founded in 2003 with more than 500 employees and 7,500-plus clients, announced its agreement to acquire MarketMuse on October 8, 2024, and completed the deal on October 31, 2024; MarketMuse's 13 employees joined Siteimprove as part of the transaction. Since then, MarketMuse's pricing page still displays four tiers — Free, Optimize, Research, and Strategy — but none of the paid tiers show a dollar figure anymore. Every quote now starts with a "Book a demo" button. Historical listings before the acquisition put the Optimize tier near $99 to $149 a month, though there's no guarantee that number still applies.
Acquisition dates and figures are drawn from Siteimprove's and MarketMuse's own press releases and independent SaaS-pricing tracking through 2026; historical pricing is reported as last publicly listed, not confirmed current.

Core proprietary technology
Integrations & platforms
Pros, cons & best for
Pros
- Patented topic modeling most tactical keyword tools don't replicate
- Personalized Difficulty scores against a site's own authority, not a generic industry number
- Free tier exists for testing the core research workflow before any sales conversation
Cons
- No dollar pricing published on any paid tier — every quote requires booking a demo
- Optimize and Research both restrict briefs to Article type; the other 8 types are Strategy-only
- Now positioned as a module inside Siteimprove's broader suite, which can slow procurement
Best for
- Enterprise content teams and agencies already evaluating or using Siteimprove
- Teams that want deep topic and cluster planning, not just single-article scoring
- Not the pick for a small team wanting to self-serve a subscription today, no sales call

Our verdict
The technology behind MarketMuse doesn't seem to be the open question here — a patented topic-modeling approach and a difficulty score calibrated to a site's own authority are things few competitors actually replicate, and that depth shows in the Topic Navigator and Strategy-tier planning documents. The open question is the buying process. Since Siteimprove's acquisition closed at the end of October 2024, MarketMuse has pulled every dollar figure off its paid tiers, which means a team can't compare its real cost against Clearscope or Surfer SEO without first booking a call and sitting through a pitch. That's a normal move for a company settling into a larger enterprise parent, but it's a real friction point for a small content team that wants to start a subscription this week, not next month. If the organization is already sizing up Siteimprove's accessibility and SEO suite, MarketMuse slots in naturally as one more module worth quoting alongside it. If the goal is simply to grade and brief content starting today, a tool that still shows its price on the page removes a step MarketMuse no longer offers.
FAQ
Why doesn't MarketMuse show its prices anymore?
Since Siteimprove completed its acquisition of MarketMuse on October 31, 2024, every paid tier moved to quote-based pricing through a "Book a demo" call instead of listed dollar amounts.
Is MarketMuse still available as a standalone product?
Yes — it continues to operate under its own name and interface, and is also sold bundled as an add-on within Siteimprove's broader packages.
What did MarketMuse cost before the acquisition?
Public listings before late 2024 put Optimize near $99–149/mo, Research near $249/mo, and Strategy near $499/mo, though none of those figures are confirmed to still apply today.
What's the real difference between Optimize, Research, and Strategy?
Optimize and Research both restrict briefs to the Article type and differ mainly in query volume and tracked topics; Strategy is the only tier that unlocks all 9 brief types and Content Strategy AI documents.
Who founded MarketMuse?
Aki Balogh founded MarketMuse in 2013, joined early by co-founder Jeff Coyle.
Does the free plan include a content inventory?
No — the Free tier is limited to 10 content queries a month, 0 tracked topics, and doesn't include content inventory features at all.
