Spam ads at the bottom of webpages make money through a pay-per-click (PPC) or pay-per-impression model. When users click on these ads, the website owner earns a small commission from the advertiser. Some spam ads also generate revenue through affiliate marketing, where the site owner gets paid for driving traffic to the advertiser’s website, resulting in sales or leads. Even if users don’t click the ads, the ad network may still pay for displaying them, depending on the number of impressions. Despite their low credibility, these ads are designed to generate as many clicks or views as possible for profit.
