Feed and take care of your neighbors’ pets while they’re out of town. Pet sitting is just like babysitting but for animals. If you’re comfortable with animals, let your neighbors know that you’re available to watch their pets when they go away. Always respect their rules and ask ahead of time if you have any questions about the care instructions.
Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease. Of course, you can appeal directly to people in your personal network, but if you're looking to generate recurring revenue sign up with a site marketing to parents looking for child care services.
Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives a commission. The advertiser must convert that visitor first. It is in the best interest of the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss are shared between the affiliate and the advertiser.
