The Verdict
Semrush is built for digital marketers and agencies, with a focus on keyword-research and site-audit. Westlaw targets law firms and corporate legal and leads with case-law and statutes.
Westlaw uses custom enterprise pricing, while Semrush starts at $139.95/mo — a tangible advantage for teams with a fixed budget.
Neither tool offers a free plan, so factor the subscription cost into your decision from the start.
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.
