What is the term for advertising that appears on a website within a search engine?

The correct term for advertising that appears on a website within a search engine is "Pay per click (PPC)." This type of advertising allows businesses to display ads in search engine results and other platforms where they only pay when someone clicks on their ad, hence the name. This model is particularly effective because it aligns the cost of advertising with the interest generated, ensuring that businesses only invest when there is a direct response or engagement from potential customers.

Display advertising refers to banner ads or graphics displayed on websites, which is distinct from how PPC functions with text-based ads typically appearing in search results. Social media ads are promotional content on social platforms rather than search engines. Affiliate marketing involves individuals promoting products or services on their platforms for a commission, which also operates differently compared to the immediate visibility and payment structure of PPC in search engine contexts.
