Have been using WiseRef for our websites network as we are in lead-gen business, it has been a game changer. It solved multiple friction points we had, starting from general business intelligence - knowing how many clicks we generate with our content and if it's growing (yeah, not every CPA partner reports that). Supporting geo-redirects ourself was painful since we had to involve programmers and complexity increased further when we started caching our content - you essentially have to implement country specific cache here, and that was just too much work that forced us to look for solution. Lastly, the fallback feature that video talks about is making us additional few hundred bucks in revenue per month - in our case it was eToro and plus500 that are not supported in some countries and we happen to get some organic traffic from unsupported countries essentially wasting those clicks into nothing, cause they had no chance of converting, being able to put alternative partners that operate in problematic countries did move the needle for us.
