There are multiple types of pay per click advertising that you can do. Paid search marketing, display advertising, social media advertising, retargeting PPC advertising, price comparison website advertising, and affiliate marketing are the main types of advertising. Display advertising is by far the most common form of advertising. These are ads you see on websites across the internet, in apps on your phone, and even on your social media platforms. Most of these ads only produce a cost when someone clicks on them; but, some sites offer standard rates for placement of a set cost for impressions (amount of times an advertisement is viewed).
