Semrush sells a SaaS platform for online visibility management, with SEO as the core use case. The platform helps marketing teams track keywords, analyze competitors, manage content, and improve search rankings. Beyond SEO, the platform extends into paid advertising, social media, content marketing, local marketing, and brand monitoring. Semrush had roughly 108,000 paying customers across 145 countries at year-end 2025, ranging from freelancers to Fortune 500 companies. Semrush uses a product-led growth model where customers sign up for free and convert through a self-service funnel, supplemented by direct sales for mid-market and enterprise accounts. Revenue is driven by recurring subscriptions across tiered plans, with customers paying more as they upgrade tiers, add seats, or adopt new products. The key growth lever is average ARR per customer, which has been rising as Semrush moves upmarket toward enterprise accounts. Enterprise customers — defined as 500+ employees — number roughly 9,000 on the platform, but only a few hundred have adopted the dedicated Enterprise SEO product, which carries an average ARR exceeding $60,000 versus the company-wide average of ~$4,400. Semrush is also building out AI-specific products that help customers track how their brands appear in AI-generated search results from tools like ChatGPT and Gemini. In October 2025, Semrush launched Semrush One, a unified offering combining traditional SEO and AI search tracking into a single workflow.
