So why do these online money-making companies give us money to make money? It's actually quite simple. Let's give a simple example: for example, watching TV advertisements, these advertising fees are paid by advertising companies to TV stations. Of course, our audience has no income. However, online money-making companies (sometimes called advertising companies) are different. While earning advertising fees, in order to encourage you to watch more advertisements, they reward users with part of their income as a commission, and it is very important that joining the online earning company is completely free, for the simple reason. Therefore, making money online is not a pie in the sky, but a commercial behavior in the era of network economy. Knowing this, it is not difficult to understand why many friends have joined various online earning companies at present, and they are very popular. Nowadays, many companies attach great importance to investigation, because investigation can help them make products that are most in line with the market, and online investigation is the most convenient and extensive investigation method. Moreover, their selective survey targets are all people in related fields, which can make the survey more accurate and let their products be known to potential customers casually.
