Digital intelligence platform for website traffic, competitor analysis, audience behavior, and market research.
Top-rated in App Intelligence#1 of 6 in App Intelligence by Overall Score
Similarweb estimates digital activity across websites and apps to help teams analyze traffic, acquisition channels, audience behavior, competitors, industries, and market trends. Its products support digital research, marketing intelligence, sales intelligence, investor research, and ecommerce analysis, using modeled and observed data sources that can be explored through the web platform and accessed programmatically through APIs.
Similarweb produces estimated digital traffic and audience patterns for external websites, instead of recording exact visits from a tag installed on each competitor domain. Its website-analysis interface supports cross-company benchmarks, but sample and modeling limitations mean these figures should not be presented as audited first-party analytics.
Calculated from facts we verified on Similarweb's own website, using published thresholds. Nobody can pay to change it. Together with Market Signal it makes the Overall Score of 73 that orders our lists.

Pricing shown reflects list prices as of our last check and may have changed. Confirm current pricing on Similarweb's website before purchasing.
Similarweb doesn't publish API prices. API access comes with its Business and Enterprise plans or as a standalone package, and either way the price is a quote from sales. We found no free API plan or API trial: the free trial on the site is for the web app.
Usage is counted in data credits, which replaced the older system of API hits. Most endpoints cost 1 credit per data point, and keyword endpoints cost 1 credit per 100 data points. Calls that fail or come back empty are free. Credits usually reset each month, unused ones don't carry over, and once you hit your allowance further requests are throttled.
To size a package, multiply domains by metrics, months and countries. Similarweb's own example is 10 domains, 5 metrics, 12 months and 2 countries, which comes to 1,200 credits.
One metric that trips people up is deduplicated audience. It's the number of individual people who visited a domain, with each person counted once even if they came on both desktop and mobile.
