I collaborated with 1ps for the first time and had heard a lot of reviews about them, including negative ones. Nevertheless, I decided to give it a try since they have commitments and a contract, which allows for demanding compliance with the terms. In my case, they fulfilled all their promises, and I was satisfied. They set up contextual advertising, selected excellent keywords, and managed the budget wisely. Overall, they did a great job. In the first quarter, we will definitely continue our collaboration, and then we'll see the results and possibly reallocate to other services.
