SimilarWeb Analyzes Billions of Digital Signals Each Day

The Intelligence Engine

  • Data Collection: We created the industry’s most diversified data universe of digital signals, constructed of statistically representative datasets that preserve variety across countries, industries, user groups and devices

  • Data Synthesis: After the data is collected, we run a sophisticated algorithmic process to clean, match, synthesize, process and blend inputs for data modeling

  • Data Modeling: Normalized data is then run through advanced machine learning calibration and predictive models to provide an accurate and consistent view of the digital world over time

  • Data Delivery: The intelligence engine generates powerful, ready-to-use insights delivered through our actionable platform or API to help you make better decisions and grow intelligently


The Data Universe: Billions of Digital Signals

We invest substantial resources to ensure that we provide statistically representative datasets that preserve variety across countries, industries, user groups and devices.

Since we started developing our leading technology for analyzing the digital world in 2011, we’ve been proactive in diversifying our data inputs to be resilient against changes in the market. Our methodology is grounded in full redundancy of these data.

We have an unrivaled blend of digital signals, collected across platforms that we categorize into 4 distinct sources:

  • Direct Measurement – millions of websites and apps choose to share their first-party analytics with us. Learn why here

  • Contributory Network – a collection of consumer products that aggregate anonymous device behavioral data

  • Partnerships – a global network of organizations that collect “digital signals” across the Internet

  • Public Data Extraction – an advanced algorithmic engine that captures and indexes public data from billions of websites and apps

First-Party Direct Measurement:

Our machine learning algorithms are fed by millions of websites’ and apps’ first party analytics (e.g. Google Analytics), both proprietary and sourced through partners. By connecting direct measurement tools to the SimilarWeb dataverse, companies put their own data in context of their market; benefitting from unparalleled insights that empower them to see their business’s performance relative to the market, leverage advanced analytics and optimize estimations.

Contributory Network

SimilarWeb manages a suite of consumer products and aggregates this anonymous device traffic data at the site- and app-level. Data is sourced across diverse audience devices to maintain an accurate and consistent view of the digital world over time.


SimilarWeb partners with a global network of organizations that capture "digital signals" across the Internet (data that help us understand how the digital world behaves). Generally, these partners produce already analyzed data for news, company information, technologies etc. Other partners aggregate behavioral data across websites and apps, and include internet operators (ISP’s), measurement companies and demand-side platforms (DSPs).

Public Data Extraction

SimilarWeb’s public data sources are an aggregation of online information available to the public. Similar to how search engines like Google index the web, SimilarWeb employs an automated technique for capturing and indexing public data from billions of website pages and apps every month. Together with census data such as country population, our advanced predictive models further refine our best-in-class estimations.

The Market Forecast: Predicting the Digital World

We employ innovative AI technologies to deliver the most powerful digital traffic intelligence available. Over the past 10 years, we have built a sophisticated set of machine learning algorithms that bring unrivaled insights to your fingertips by:

  • Cleaning each individual input for data normalization

  • Matching data inputs for consistent grouping across digital properties

  • Synthesizing billions of data inputs for categorizing and advanced, predictive modeling

  • Processing structured data for noise and bias reduction

  • Blending models for weighting and scientific calibration

  • Reporting key insights on any market, company or audience for an authoritative and accurate view of the digital world

Our industry-leading technology is supervised using a cross-validation process to ensure scale and trend accuracy on a daily basis – so you can be confident that you’re privy to the right market trends at the right time. Perfecting your digital strategy is hard, but with SimilarWeb, getting the needed insights doesn’t need to be.
