Pros and cons

What Similarweb does especially well — and the limits to anticipate.

Pros

Broad coverage of traffic and competitive data.
Free web tools for quick lookups without an account.
Market benchmarking and traffic-source analysis.
Keyword and search-share research.

Cons

No permanent free plan: only a limited trial.
Business plans are expensive and quote-only.
Estimates, not exact numbers from your own data.

Similarweb: when it makes sense.

Similarweb makes sense for competitive and market intelligence at scale; for your own site's analytics or occasional checks, a free solution fits better.

Keep if

You do competitive and market analysis (traffic, sources, benchmarks).. You need traffic estimates for third-party domains.

Similarweb becomes worthwhile when

You use it at least once a week
The monthly cost (€20) is small next to the time it saves you

Challenge if

You only need your own site's analytics: a free tool (Analytics) suffices.. Your budget is limited: paid plans are expensive and quote-only.

Similarweb becomes too expensive when

You use it less than once a month
A simple free version or a tool already in your stack would do
