Is client-side tracking bad for detecting foreign ad clicks?

Client-side tracking is vulnerable to signal loss from ad blockers and browser privacy rules, so it can miss the data needed to detect foreign VPN clicks. Seatext's solution uses first-party server-side synchronization to eliminate client-side dependencies and capture cleaner signals. That makes it easier to spot clicks from non-shippable visitors. It also helps ad algorithms stop targeting this low-quality traffic.
