How does DeepSee work?

Make discovering and vetting quality publishers with strong brand alignment a breeze.

Tags are passive. We are active.

Legacy verification relies on sampling; we rely on evidence. Our crawlers navigate the open web as a human would, gathering ground-truth data to distinguish premium publishers from the MFA farms that mimic them.

Quantify, Don't Guess

We go beyond pixel counting to model the actual user experience. By measuring "hostility" factors like aggressive refresh rates alongside rich contextual analysis and brand safety signals, we prove where ads are actually seen and respected.

Audit for Policy & Fraud

Ensure every impression meets the standard. We verify inventory against the strict compliance policies of major DSPs and SSPs, flagging policy violations and sophisticated fraud before you bid.

Bad actors rarely work alone

We map the intricate web of relationships between domains, ad managers, and their supply chains. By visualizing these hidden connections, we distinguish legitimate publishers from arbitrage rings and other unwanted sources.

Let the numbers speak for themselves.

Stop subsidizing arbitrage. By cutting out uninhabited sites, our clients saw their return on prospecting spend more than double.
