Many aspiring experts and entrepreneurs are terrified of investing in marketing. They rely solely on free methods: Reels, Shorts, mutual PR, or word of mouth. While this might bring in some initial clients, it's impossible to build a stable, predictable, and large-scale business on it. Free traffic is a roller coaster: algorithms give you reach one day, and the next they cut it to zero, leaving you with no sales. Buying ads isn't an expense; it's an investment in your money-making machine. You need to understand clearly: if you invest 10,000 rubles in traffic, you'll get clients worth 30,000 rubles. Once you shift this mindset and stop being afraid to click the "pay for advertising" button, your income will reach a whole new level.
