I compared the database collection and profitability of Clickstar with Pushprofit and Realbig. I tested each of them for a week: RB showed around 20, PP – 24, while CS – 90. The difference was more than 4 times. I didn't change the subscription block settings; all conditions were the same for the accuracy of the experiment. Regarding profitability, RB and PP lag behind in cost per click, with Clickstar offering more favorable conditions. The difference is also significant: about 60 kopecks per click from PP and 2.5-3 cents on CS. There are many reasons for such a difference. For example, PP works with loyalty, like stores with points, which ultimately affects the price since people are more inclined to go for freebies. CS does not have such practices, so prices are higher. Speaking of traffic buyout, it will be particularly interesting for arbitrageurs here. The prices for buying pushes are simply excellent, offering good amounts for the CIS, and the best for Russia – 42-52 dollars for 1,000 subscriptions. The price range depends on desktop and mobile traffic. The network covers many countries, with over 200 connected, so with quality traffic, you can earn quite well. With large volumes, the price may increase, which would be a great option! Therefore, it's worth coming here at least for the higher conversion compared to other affiliate programs.
