The service evokes mixed feelings. On one hand, you can't earn serious income from your site using it, but on the other hand, you can at least make a small amount from a platform that other ad networks do not accept. If your traffic doesn't reach the level for AdSense or RSEA, or if you're using free hosting (like Ucoz), then LinkSlot will be a good choice. It's also convenient because it fully automates the earning process. You only need to place the banner code on your site once, and then just keep an eye on price changes and ad moderation. The banner sizes are the most popular: 468 by 60, 720 by 90, 200 by 300, and others. If the space is free, a placeholder is set, and anyone interested can buy it. Earnings come from renting out the banner space. The minimum amount for withdrawal is 100 rubles.
