Voluum is the cloud tracker most serious media buyers benchmark everything else against. Built on a globally distributed infrastructure, it handles hundreds of millions of ad events daily with sub-100ms redirect speeds. Its traffic distribution rules engine is genuinely powerful - you can route by device, carrier, language, and custom variables without touching code - and the built-in anti-fraud layer filters bot clicks before they pollute your conversion data. The affiliate network integration library is one of the deepest in the category.

Plans start mid-tier and climb steeply for high-volume usage, so it's overkill for buyers spending under a few thousand dollars a month on media.
