Select the correct answer. The CPC payout model is most typically used in the following digital marketing channel:

Paid Search (e.g., Google Ads, Bing Ads) primarily operates on a Cost-Per-Click (CPC) model, where advertisers pay each time a user clicks on their ad. This is fundamental to how search engines monetize their advertising platforms. Influencer marketing often uses flat fees or performance-based models like Cost-Per-Acquisition (CPA) or revenue share, not typically CPC. Affiliate and Partnerships marketing is generally performance-based, using CPA, Cost-Per-Lead (CPL), or revenue share. Organic Search does not involve direct payment per click; its traffic is earned through Search Engine Optimization (SEO) efforts.
