Cost Per Click (CPC) determines the cost that advertisers pay for each click their ads receive, making it an important factor in digital advertising. It’s a valuable tool for controlling ad spending and assessing campaign effectiveness. Advertisers set their CPC through bidding, but the final cost is influenced by ad quality, keyword relevance, and competition. CPC helps guide budget management and performance analysis. To achieve lower CPC rates, advertisers should focus on improving the quality and relevance of their ads, fine-tuning keyword targeting, and adjusting bidding strategies accordingly.
