Go with TrafficShield.io. Keitaro is too complicated for your first time since it's a tracker, not a plug-and-play cloaker. Adspect is good for RU traffic but way too expensive ($499+) if you're just starting out. TrafficShield starts at $49, which is much better for beginners to test Yandex ads on a low budget. Just make sure before applying cloaking, warm up your account well so it will survive longer.
I’ve been using TrafficShield for a while. I was mainly looking for zero-redirect cloaking, and the other cloakers I checked were more expensive. TrafficShield was more affordable for what I needed.
I’d test them with a small campaign first. For Yandex, tracking and filtering are the main things I’d look at. Setup is pretty subjective, so see which one fits your workflow better.
Don’t choose only by features, check stability and support also. Those things become important when you start getting more traffic.
For Yandex Ads, ease of setup and good tracking would be the main things to compare. Since this is your first time, start with the simplest option and test it before scaling.
In your opinion how are yandex ads different from google or facebook?
I think yandex is more focused on search intent, especialy in Russia, Fb is more interest based and google has more global reach.
If this is your first time i would suggest not using self hosted configuration can be bit difficult if you just starting . use a cloud based one first, it will be easier ,once you learn it properly, you can move to self hosted.
