SimilarWeb is a website that provides web analytics services for businesses. The company offers its customers information on their clients' and competitors' website traffic volumes, referral sources which include keyword analysis and demographics, and website "stickiness" (e.g., time on site, page views, bounce rate), as well as other features.
It extrapolates data from a panel of web users who allow the monitoring of their internet activity, combined with direct observations for a subset of internet properties, such as websites' own traffic statistics. In 2019, it claimed to have the world's largest panel, with hundreds of millions users.
The company was founded in 2007 by Or Offer in Tel Aviv, Israel. By 2009 SimilarWeb won the first Israeli SeedCamp, attracting the attention of international media and investors. The company raised its Series A round of $1.1 million with the investment being led by Yossi Vardi, and Docor International Management. SimilarSites, a browser extension to help users find sites similar to those they are visiting, was launched later that year.
On September 24, 2013, the company closed a $6 million Series B round led by David Alliance, Moshe Lichtman with the participation of existing investor Docor International Management. On February 24, 2014, South Africa media giant Naspers invested $18 million into SimilarWeb and leading their Series C round. Within a month, SimilarWeb used a part of the capital for the acquisition of Israeli early-stage company TapDog for a few million dollars in shares and cash, less than a year after TapDog was founded. In November 2014, SimilarWeb raised $15 million in a series D investment. In July 2015, SimilarWeb acquired personalized content discovery platform developer Swayy.
On December 10, 2015, SimilarWeb announced it had acquired Quettra, a Silicon Valley-based mobile intelligence startup, to boost its mobile operations. Quettra provided personalization tools for developers in return for detailed mobile telemetry data.
In July 2017, the company announced a $47 million round of financing led by Viola Growth, Saban Ventures with participation from CE Ventures and existing investors.
On September 8, 2019, SimilarWeb updated the algorithm that use to produce traffic and engagement statistics. The update took into account the behavior of visitors to similar kinds of sites to improve the depth and dependability of their data.
