Semrush vs MarketMuse

Semrush, an Adobe company, is a nine-toolkit suite spanning SEO, content, local, social and advertising, with an AI visibility module tracking five engines, metered by prompts per tier. MarketMuse, part of Siteimprove, models Google's results pages: topic modeling with personalized difficulty, research-backed briefs, draft scoring against the top 20, and site-wide content inventory. They compete only where the categories overlap, and the chapters below walk every dimension a buyer would price: which AI engines each can see, how the tracking actually meters, what each produces on the content side, what surrounds the core product, and the full published tier lists.

Semrush, now an Adobe company, is the biggest suite in search marketing, with homepage scale stats of 28 billion keywords, 43 trillion backlinks, 808 million domain profiles, 142 geo databases and 289M+ LLM prompts. Nine toolkits share one login across SEO, traffic analytics, content, local, social, advertising and PR, and the AI visibility module tracks how often your brand appears in answers from ChatGPT, Perplexity, Gemini, Claude and AI Overviews, with sentiment and custom prompt monitoring from the entry SEO plan.

Pricing model. SEO $139, Starter $199, Pro+ $299 and Advanced $549 a month billed monthly, with annual billing saving up to 17% ($117.33 to $455.67); AI prompt tracking is metered at 50, 100 and 200 prompts daily by tier, and a free $0 plan offers one demo project.

MarketMuse, now by Siteimprove, is a content strategy platform with a decade of iteration on modeling Google's results pages: Topic Navigator, SERP x-ray, SERP and Site Heatmaps, topic models that produce difficulty scores personalized to your domain, and a Content Inventory that crawls your whole site and tracks decay. Its Optimize product scores a page one-to-one against the top 20 ranking pages with E-E-A-T signal measurement, and its brief generator produces research-backed briefs in nine types on the top tier.

Pricing model. Four tiers, Free, Optimize, Research and Strategy, metered by tracked topics (10 queries a month free, 100 to 10,000 topics paid) and content briefs (5 to 20 a month); no dollar figures are published and every tier's button, including Free's, books a demo.

Semrush. The features page publishes the engine list: ChatGPT, Perplexity, Gemini, Claude and AI Overviews, making Semrush one of the few big suites with Claude included. Grok, DeepSeek and Google AI Mode do not appear in that list.

MarketMuse. No AI answer engine appears anywhere on MarketMuse's public pages: no ChatGPT, Claude, Gemini, Perplexity or AI Overviews. The platform's entire measurement surface is Google's results pages.

Summarized: Semrush reads 5: ChatGPT, Perplexity, Gemini, Claude, AI Overviews; MarketMuse reads none; the surface is Google's SERPs. On Claude specifically, Semrush: yes; MarketMuse: no.

Semrush. AI prompt tracking meters by tier: 50 prompts daily on Starter, 100 on Pro+, 200 on Advanced, alongside classic position tracking with 500 to 5,000 keywords and 5 to 40 monitored websites. AI brand sentiment and AI visibility reports for any domain ship from the $139 SEO plan.

MarketMuse. Measurement is SERP analysis at depth: SERP x-ray and heatmaps, topic models with personalized difficulty, and the Content Inventory crawling your site to flag decay. There is no position tracker in the rank-tracking sense and no answer recording.

Semrush. The content toolkit generates full-length, SEO-ready articles from a brief, with AI features woven through Domain Overview and Keyword Suggestions. CMS publishing targets are not enumerated on the pricing or features pages, so where the generated article lands is a question for their sales team.

MarketMuse. Briefs are the product: structure, subtopics, questions and linking suggestions, research-backed, metered per month by tier, with draft scoring against the top-20 pages. Output exports to Google Docs or MS Word for your writers; there is no CMS publishing, so the distance from brief to published page runs through your team.

Semrush. Classic SEO is the suite's backbone: position tracking, a technical site audit crawler, the 28B-keyword research database and the 43T-link backlink index. A local toolkit with listing management and map rank tracking exists; whether it draws a geo-grid or covers Apple Maps is not stated on the rendered pages.

MarketMuse. There is no local product: no map tracking, no GBP tooling, no citations.

Semrush. MCP access lists from the $199 Starter tier and API data integration only on the $549 Advanced tier. White-labeling arrives through the Pro Report add-on at $20 a month, and the suite's own research database is the underlying asset most buyers pay for.

MarketMuse. No public API documentation exists (the /api page 404s and the developer subdomain refused connections when checked) and no MCP server is listed. Exports cover saved writing, applications and documents.
