Zvelo releases ‘first free bot detection service’

Zvelo, a Denver-area firm whose services include content categorization and malicious detection data, is today launching what it describes as the first free bot detection service.

A Javascript tag is inserted into an ad or a web page, so that the service can analyze the activity of each visiting browser to determine if the user is non-human (that is, a software bot). The service is also designed to detect “low-quality traffic” (LQT), where people are paid to quickly surf ads or sites.

The detected browser signals include mouse movement, time on page, browser properties, the amount of the web page visible in the browser and other signs. A dashboard displays percentages of Non-Human Traffic (NHT) or LQT:

Those percentages indicate if there’s a problem, Zvelo President and CEO Jeff Finn told me. If the advertiser or site wants to take action, he said, his company offers a paid data feed called the Invalid Traffic Dataset, which provides the specific IP addresses of the detected bots or LQT.

In a typical use case, he said, the advertiser that has decided it has a problem would instruct a demand-side platform (DSP) to decline a real-time bid to any of those IP addresses. Because bots frequently change their addresses, the feed is updated every 15 minutes.

Finn said about two-thirds of his company’s customers are DSPs, and the remainder are supply-side platforms (SSPs) that are working with publishers to clean up their inventory or create premium sections.

Zvelo conducted a closed beta of the service with selected customers for three months. Finn said the bot detection service’s accuracy is “above 90 percent,” with non-human traffic generally in the 10 to 40 percent range for most customers and low-quality traffic about 5 to 10 percent.
