Clay vs Semrush
A side-by-side breakdown to help you pick the right tool for your workflow.
Clay
Pull, enrich, and act on contact and company data through one workflow builder connecting dozens of data providers and AI models. New Actions + Data Credits pricing split platform usage from enrichment cost.
Semrush
Research keywords, track rankings, and now monitor how your brand shows up in AI answer engines like ChatGPT and Google AI Overviews. New Semrush One bundle adds AI-visibility tracking.
Bottom Line
Last reviewed: August 2026
Clay and Semrush both sit in Marketing, but they're built around different use cases within it. Both carry the same 4.7 rating, so the decision comes down to fit, not quality.
Choose Clay if…
Best for go-to-market teams that need enriched, verified prospect data pulled from many sources at once, and its edge is 75+ data providers combined into one pipeline that resolves conflicts and produces a single clean record. The most powerful enrichment tool on the market, expensive and credit-hungry enough that it rewards a team that already knows what it's doing.
Choose Semrush if…
Semrush is built for marketers and SEO professionals whose job involves ongoing competitive research, not for anyone who checks rankings once a month. The keyword database at 25 billion keywords and the newer AI-visibility tracking for ChatGPT and Google AI Overviews add a monitoring layer older SEO tools haven't caught up to.
