House sit if you have neighbors who go on vacation. Water their plants, take out the trash, check the mail, and keep an eye on things. They may ask you to visit 1 to 2 times a day or even spend the night at their house so it doesn’t look empty and prevents burglary. Follow all of your neighbor’s rules and instructions and always lock up the house when you leave to keep it safe.
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.
Forms of new media have also diversified how companies, brands, and ad networks serve ads to visitors. For instance, YouTube allows video-makers to embed advertisements through Google's affiliate network. New developments have made it more difficult for unscrupulous affiliates to make money. Emerging black sheep are detected and made known to the affiliate marketing community with much greater speed and efficiency.
