when I decided to reallocate the budget, I took a small step aside to check how 1win would behave with average volumes. at first, I thought that I would just have to sit for days and catch distortions, but the schedules turned out to be calmer. The depth of the statistics allowed me to see micro-deviations, and I gradually transferred some of the traffic from native to a mixed format.
One of the interesting points was the behavior of traffic on Asian geo sites: no unexpected cross-sections, and this is rare. payments went according to schedule, without sudden delays. I even noted that convenient promos help save time on preparing creo for rotations. The structure of the materials is consistent, there are no outdated templates.
the support in one dialogue was able to synchronize with me an understanding of exactly where the filter clings in my tracking. a nice detail: there was no unnecessary rush, and the answers were given on the case.
now I'm thinking of gently expanding the test: not chasing rapid growth, but seeing how new sources behave. a calm, even experience.
