The Verdict
Semrush is built for digital marketers and agencies, with a focus on keyword-research and site-audit. The Trade Desk targets media buyers and agencies and leads with programmatic-buying and connected-tv.
The Trade Desk 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. The Trade Desk requires a paid subscription from day one.
Feature-wise, Semrush offers broader built-in capabilities (7 features vs 6), while The Trade Desk 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.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
