Any business needs a lead flow. When there is a clear positioning, the lead flow is relatively easy to acquire through the chain "online advertising -> landing -> target action". The target action is any "I'm interested" button (it is also called a CTA button from English Call To Action), which the lead clicked, leaving their coordinates. But when you do not have a clear positioning, you need to "go to the masses" - where your target audience hangs out, including the audience of your competitors.
