I've been running my travel group on VK for several years now, and I have about 60,000 subscribers. Compared to regular advertising for other partnerships, I haven't found any significant advantages here, but every month I managed to withdraw around 7-8 thousand (in spring and summer, as well as at the beginning of autumn, and then – almost nothing). In terms of income, the situation is quite disappointing: on average, I received about 1.5% of the ticket price sold and about 3% of the booking amount. The statistics easily allow you to calculate the number of clicks and orders, including paid ones. Money was credited to WebMoney on the 10th of each month, and the transfer took just a few hours. Payment is made in two ways: when purchasing tickets – almost immediately after booking, and for reservations – a week after the client departs. The main advantage is that I placed the link in the group's header and forgot about it; clients do everything themselves, so as a form of passive income, it's not bad. However, you can't earn much here; after all, it's a "seasonal" partnership.
