Our verdict: Semrush instead of SimilarWeb?

Switch if: Full-stack digital marketing teams who want the closest single-vendor replacement for SimilarWeb — the Traffic & Market toolkit plus One2Target replicates most of SimilarWeb's traffic, channel, and audience reports while adding much deeper SEO and PPC tooling.

Don’t switch if: Freelancers or small businesses who only need occasional competitor traffic lookups — the SimilarWeb-like features are locked behind an expensive add-on on top of an already pricey base plan.

Biggest caveat: The SimilarWeb-equivalent features (Traffic Analytics, Market Explorer, One2Target) are NOT in any base plan — they require the Traffic & Market (.Trends) add-on at roughly $289 per user per month on top of Pro/Guru, and Trustpilot reviewers repeatedly report the multi-step, email-confirmed cancellation flow silently failing and billing continuing.

What Real Users Complain About

Negative feedback found on public platforms — because every tool has trade-offs, and vendors won't show you these.

The biggest downside is probably the price. It is a really powerful tool but it can get expensive, especially for small teams or solo people.

This is getting out of hand. $199/mo for a 'Starter' plan is wild. At that price point you're paying almost $2,400/year just for basic SEO data.

Reddit r/SEO

SEMRush guesses competitor traffic and every time I have looked it can be 10x off the truth.

Reddit r/SEMrush

The numbers can be a bit unreliable. Keyword volumes, difficulty scores, traffic estimates, and backlink metrics are all just estimates.
