Bot traffic on open exchange programmatic campaigns
Open exchange RTB is the primary environment for sophisticated and general invalid traffic, with 20-40% of impressions generated by non-human traffic that your DSP pays full CPM rates for.
Trusted by leading brands worldwide
Open exchange RTB is structurally designed for speed, not traffic quality verification
The open exchange processes billions of impressions per day in auction cycles measured in milliseconds. No human reviewer can assess traffic quality at that speed, and the economic model incentivizes scale over quality: publishers earn revenue for every impression served, creating a direct financial incentive for bad actors running inventory to maximize their bot traffic volumes. Industry estimates consistently put open exchange IVT rates between 20-40%, meaning a substantial share of every programmatic display budget is consumed by impressions that no real person ever saw.
Sophisticated invalid traffic on the open exchange is specifically engineered to evade standard detection. SIVT operations use residential proxy networks, browser emulation, and human-like interaction timing to pass the basic bot filters that rely on known datacenter IP ranges and user agent strings. Standard brand safety tools, which screen content at the domain level, cannot detect whether a given impression is being served to a real user or to a bot simulating a page view. Tapper analyzes traffic at the device and behavioral level, identifying SIVT signatures across your entire open exchange buy.
How Tapper stops bot traffic on Display open exchange
Three steps from connection to clean campaign data, no engineering required.
01
Integrate Tapper with your DSP or ad server
Tapper connects to your demand-side platform and begins monitoring impression and click data across all your open exchange inventory, building a real-time picture of traffic quality.
02
SIVT and GIVT patterns detected at the impression level
Behavioral fingerprinting, device analysis, and IP reputation scoring identify bot signatures including headless browsers, datacenter IPs, and non-human interaction sequences, even when residential proxies are used.
03
High-IVT inventory sources suppressed automatically
Publishers and inventory sources linked to bot traffic are added to suppression lists applied to your future open exchange buying, reducing exposure with every campaign cycle.

“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimizes against cleaner signals and the efficiency comes through quickly. For AMA Nissan, that was a 40% lift in conversion rate and a lower CPA on Google, with nothing else in the setup changing. That is the kind of result we want to offer clients as a matter of course.”

Frequently asked questions
The open exchange has minimal publisher vetting. Any publisher can submit inventory into the RTB bid stream with limited scrutiny, and low-quality or entirely invalid inventory sources benefit from the same auction infrastructure as premium publishers. Private marketplace and programmatic guaranteed deals involve direct relationships and vetting that significantly reduce, though do not eliminate, bot exposure.
GIVT, or general invalid traffic, includes basic bot crawlers and data center traffic identifiable by known IP ranges and user agent lists. SIVT, or sophisticated invalid traffic, uses residential proxies, browser emulation, and human-like interaction patterns to evade standard detection. On open exchange inventory, both types are endemic, but SIVT is the harder problem and accounts for a growing share of total bot impressions.
Bot impressions register as served in your DSP reporting, inflating your impression count while your genuine viewability rate falls. When bots simulate a page view, the impression is counted but no real human sees the ad. Your reported viewability rate is the average across real and bot-served impressions, masking how few of your genuine audience-delivered impressions were actually visible.
