What type of advertising model do online review sites like Yelp and Google generally use?

Online review sites like Yelp and Google primarily utilize a pay-per-click advertising model. This model allows businesses to create ads that are displayed alongside search results or on their profiles within the site. When a user clicks on these ads, the business is charged a fee. This approach is particularly effective for local businesses looking to attract customers who are actively searching for services in their area.

By using the pay-per-click model, these platforms can generate revenue directly from advertisers while providing users with relevant options based on their search queries. This model also aligns with the user's intent, making it advantageous for both businesses and consumers. The flexibility and scalability of pay-per-click advertising make it a preferred choice for online review sites, encouraging businesses to engage with their audience effectively.
