Best Free SEMrush Alternatives in 2026 (Compared)

SEMrush (now Semrush) costs $139.95/month for the Pro plan — and that's for a single user with capped reporting limits. For freelancers, bootstrapped startups, and small agencies, that's a significant overhead. These alternatives match most of Semrush's core capabilities at a fraction of the price.

The Semrush pricing problem

• checkPro plan: $139.95/month — 5 projects, 500 tracked keywords, 10,000 results per report
• checkGuru plan: $249.95/month — adds historical data and content marketing toolkit
• checkBusiness: $499.95/month — adds API access and extended limits
• checkFree plan: 10 searches/day, extremely limited — effectively a demo

Top free and affordable Semrush alternatives

RankWhiz vs. Semrush: honest comparison

Semrush is built around dashboards — you pull reports, export data, and interpret it yourself. RankWhiz inverts this: ask a question in plain English and get a structured answer backed by the same underlying data. For most day-to-day SEO tasks (keyword gap analysis, on-page recommendations, rank tracking), RankWhiz is faster. For deep programmatic data pulls via API, Semrush still leads.

SE Ranking — Best direct Semrush substitute

SE Ranking offers the most Semrush-like feature set at a significantly lower price. You get keyword research, competitor analysis, a site auditor, rank tracking, and backlink monitoring. The interface is traditional (dashboard-based), but coverage is solid and pricing starts at $52/month for small teams.

Ubersuggest — Best for budget keyword research

At $29/month ($290 for a lifetime deal), Ubersuggest covers keyword research, basic competitor data, and a site audit. It's not as comprehensive as Semrush, but for bloggers and single-site owners who mainly need keyword ideas and on-page recommendations, it's a solid value.

Our recommendation

If you're canceling a Semrush subscription, RankWhiz covers keyword research, competitor analysis, backlinks, technical SEO, and AI search visibility in one tool — for $25/month vs. $139.95. If you need Semrush-style dashboards and bulk data exports, SE Ranking ($52/month) is the closest structural match.
