MarketMuse

MarketMuse is an AI content strategy and SEO platform operated by Siteimprove, which acquired it in November 2024. The terms of service state that the services are made available by Siteimprove and were formerly provided by MarketMuse, Inc. It is built for content marketing teams, SEO agencies and publishers that plan content around topics rather than single keywords. Core capabilities are topical authority modeling, AI content briefs in nine brief types, content scoring, a scored site content inventory, content gap identification, strategy documents and Connect, its internal-linking feature. Its Newsroom feature analyzes news results to show what a story needs to rank in news search. WordPress is the content management system connector documented in MarketMuse's knowledge base, through articles on moving content from the Optimize editor into a CMS. MarketMuse does not publish an integrations directory or public API documentation, and it does not publish an MCP server. Siteimprove lists four MarketMuse plans with their limits but no published rates, and every plan card routes to a demo booking. Free covers 1 user and 10 queries per month. Optimize adds 1 site inventory, 100 tracked topics, 5 content briefs and 1 strategy document per month, with 100 queries. Research raises that to 3 users, 1,000 tracked topics, 10 briefs, 3 strategy documents and unlimited queries, and adds Keywords, SERP X-ray and SERP Heatmap. Strategy offers 5 users, 10,000 tracked topics, 20 briefs, all nine brief types, 5 strategy documents, and Site Heatmap with Connect. Fees are stated and payable in US dollars under the terms of service. The product signup page states that sign up is disabled and directs prospective users to contact sales, so access to every plan, including Free, starts with a sales conversation. Connect and Site Heatmap are limited to the Strategy plan. The terms of service make the customer responsible for keeping personal data out of what it submits to the AI features. MarketMuse suits content and SEO teams, agencies and publishers that plan content programs around topic clusters and want briefs, inventory scoring and gap analysis to direct what gets written next. Teams that want self-serve, page-by-page optimization while drafting should consider Surfer or Clearscope. Teams that want research, AI writing and publishing in one loop should consider Frase. Current state Q4 2026: MarketMuse operates under Siteimprove, with no published rates and no self-serve signup. Its AI features are powered by third-party providers named in the terms of service as OpenAI and Amazon Bedrock. Siteimprove holds an ISO 27001:2022 certificate issued by the British Assessment Bureau in March 2024, which names no product scope, and MarketMuse's privacy policy states that the company is GDPR compliant.
