Fingerprint Pro works best if the JavaScript agent is installed and runs an identification for every visitor on every page of your website. To estimate the number of identifications this installation would use, you can look at your website’s total number of monthly pageviews using a client- or server-side website analytics service (e.g. Google Analytics, Segment, Netlify Analytics).

If you decide to install Fingerprint Pro only on several key pages (e.g. signup, login, or prepayment), then you use pageviews for those specific pages as an estimate for identifications.

Finally, if you plan to configure Fingerprint Pro to only identify visitors when they first land on your site, you can use monthly user sessions to estimate identifications needed.

For assistance in estimating the number of identifications needed for your use-case, please contact sales.

Fingerprint Pro combines over 100 unique signals to create a unique and stable visitorId with 99.5% accuracy. We are able to achieve such high accuracy through continuous testing and iteration of signals as browsers and devices change, as well as machine learning algorithms that can identify when a visitor is trying to change their identity via proxies or other techniques.

In a recent browser fingerprinting study from KTH Royal Institute of Technology, only 33.6% of users were correctly identified. Other studies from the Electronic Frontier Foundation and Inria saw fingerprint accuracy between 80-90%, but those studies predate current web privacy policies and technologies. Fingerprint Pro’s 99.5% accuracy is higher than any other service on the market.
