Semrush vs AthenaHQ

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. AthenaHQ tracks brand visibility across up to nine AI models with prompt and response analysis, competitor insights, and content optimization agents, with a real free tier. 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.

AthenaHQ is a San Francisco AEO platform with strong review credentials: a G2 High Performer for Answer Engine Optimization (Spring 2026) and 4.9-out-of-5 ratings on its badges. The product analyzes prompts and responses across up to nine AI models, estimates prompt volumes numerically, tracks unlimited competitors with sentiment, and acts through on-page and off-page GEO actions, a content optimization agent, smart robots.txt and llms.txt management, and an enterprise citation engine (ACE). Unlimited seats with role-based access come on every plan, and it publishes its own comparison pages against Profound, Peec, Scrunch, Semrush and Ahrefs.

Pricing model. Essential is free with a $25 credit (300 credits, five models including Claude); Starter is $295 a month with a $300 monthly credit (3,600 credits, nine models), with API access and extra credits as paid add-ons; Enterprise is custom with annual 17% off available.

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.

AthenaHQ. The free Essential tier covers ChatGPT, Perplexity, AI Overviews, Gemini and Claude; Starter adds AI Mode, Copilot and Grok for visibility across nine models, with additional models available on request. Claude ships from the free tier, which is rare in this set; DeepSeek does not appear on the page.

Summarized: Semrush reads 5: ChatGPT, Perplexity, Gemini, Claude, AI Overviews; AthenaHQ reads 5 free; 9 on Starter (incl. Claude, Copilot, Grok, AI Mode). On Claude specifically, Semrush: yes; AthenaHQ: yes, from the free tier.

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.

AthenaHQ. Metering is credit-based with one credit equal to one AI response: 300 credits free, 3,600 on Starter, custom on Enterprise. Tracking includes unlimited topics, numerical prompt-volume estimation, unlimited competitor tracking and benchmarking, prompt variations with conversation context, and real-time brand sentiment.

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.

AthenaHQ. Content recommendations ship on the free tier and a content optimization agent from Starter, with brand voice and guideline enforcement, on-page and off-page GEO actions, and Shopify and Webflow integrations. The enterprise Athena Citation Engine and Recommendation Engine extend the action layer; there is no long-form article pipeline described.

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.

AthenaHQ. There is no Google organic rank tracking and no local surface on the pricing page. GA4 and Google Search Console integrations connect AI visibility with site traffic, which correlates traffic with visibility; position measurement is a different job.

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.

AthenaHQ. CSV export ships from Starter, GA4 and GSC integrate, and API access is an optional paid add-on billed on top of the Starter subscription, included only on Enterprise. Enterprise adds SAML and OIDC SSO, audit logs, multi-region and multi-language support, and executive dashboards with Tableau, Power BI and Looker support. No MCP server is listed.
