    You manage SEO for at least one site professionally and need keyword, rank, and backlink data in one place.

    • API access is reserved for the $549/month Advanced tier.
    • The free plan is a limited demo (1 project, 10 reports/day), not a usable free version of the tool.

    Choose Similarweb

    You're a team that regularly needs multi-market competitive intelligence across web, SEO, ads and apps, and can justify a recurring sales-quoted contract.

    Watch out

    • No public self-serve pricing; most useful tiers require a sales conversation and can run into five figures a year.
    • Estimated (not measured) traffic data can be significantly off for smaller, lower-traffic sites.
