What bidding strategy do Website Clicks campaigns use?

Website Clicks campaigns on Twitter are optimized to drive users to a specific URL, and the most direct and relevant bidding strategy for this objective is Cost Per Click (CPC). With CPC, you pay each time a user clicks on your ad, directly aligning your spending with the desired action of driving traffic to your website. CPAC (Cost Per App Click) is incorrect because it's specific to app install campaigns, not website visits. ROAS (Return on Ad Spend) is a performance metric and a bidding strategy used for campaigns focused on revenue generation, not typically the primary bidding strategy for simple website clicks where the immediate goal is traffic.
