I’ve read stories about people setting up ad campaigns and making thousands of dollars within a matter of hours. What’s the catch? The big one is risk. You’re spending money to make money, so if you turn out to set up a bad ad campaign that doesn’t convert well, you can easily lose lots of money. That’s been the primary reason I’ve stayed away from this method of making money online. I’m not going to bother giving advice here, because as I said, this isn’t something I’ve done. If you’re interested, you can probably find a lot of good information via Google, but watch out – as with any other internet marketing topic, most everyone is going to try to sell you something.
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
