Google Ads operates on a pay-per-click (PPC) model where advertisers bid on relevant keywords, and the auction system determines ad placement based on bid amount and quality score. Advertisers set daily budgets, paying only when users click on their ads. Quality Score, influenced by ad relevance and user engagement, impacts ad rank. Various ad formats, including search, display, and video ads, cater to diverse marketing needs. Targeting options, ad scheduling, and extensions enhance ad precision and visibility. Conversion tracking and analytics tools enable advertisers to measure and optimize campaign performance, making Google Ads a versatile and data-driven platform for effective online advertising.
