The Verdict
Google Ads is built for businesses and agencies, with a focus on search-ads and display-ads. Semrush targets digital marketers and agencies and leads with keyword-research and site-audit.
Google Ads uses custom enterprise pricing, while Semrush starts at $139.95/mo — a tangible advantage for teams with a fixed budget.
Semrush has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Google Ads requires a paid subscription from day one.
Feature-wise, Semrush offers broader built-in capabilities (7 features vs 6), while Google Ads takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for agencies — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Semrush has a slight overall edge — but if massive reach matters most to you, Google Ads may still be the right call.
