Similarweb
Similarweb is a digital market intelligence tool that estimates any website's traffic, channels and audience, for marketing, research and sales teams sizing up competitors and accounts.
Updated October 2026
Overview: What is Similarweb?
There's a free traffic checker, and paid web plans start at $125 a month billed annually (checked October 2026).
Similarweb models traffic for public websites and breaks it down by channel, country, referral sources and keywords. Beyond competitor research it sells a Sales Intelligence product that flags account signals such as traffic shifts, technology changes and news, with prospecting and meeting prep agents. The company was founded in 2007 in Tel Aviv and is listed on the NYSE as SMWB.
Fit: Ideal customer profile.
Marketing, research and sales teams at companies whose buyers or competitors have meaningful web traffic, such as ecommerce, media and software. Single users can start self-serve. Teams that need CRM sync or the API should expect a quoted contract, and estimates are weaker for small, low-traffic sites.

Questions
Frequently asked.
How much does Similarweb cost?
The Competitive Intelligence plan is $125 a month billed annually or $199 month to month, and Sales Intelligence Individual is $99 a month billed annually. Business and Enterprise are quoted (checked October 2026).
Is Similarweb free?
There's a free Website Traffic Checker with three searches a day and a 7-day trial of paid plans. Full history, keyword data and exports need a paid plan.
How accurate is Similarweb traffic data?
The numbers are modelled estimates, not a site's own analytics. They're most useful for comparing sites and spotting trends, and least reliable for small sites with little traffic.
Does Similarweb integrate with Salesforce and HubSpot?
Yes, with two-way sync, but only on Business and Enterprise plans. The API and MCP access are also on quoted plans.
What are Similarweb's limits?
Every self-serve plan is a single seat, entry plans keep only three months of history and a small credit pool, and CRM sync and the API need a quoted contract.
What are the alternatives to Similarweb?
Semrush and Serpstat focus on SEO and keyword research with traffic estimates. BuiltWith and Wappalyzer show which technologies a site runs, and D&B Hoovers is company and contact data for B2B targeting.
