Google Ads does not have a specific minimum CPC rate. Instead, it operates on an auction system where the cost is influenced by various factors. Advertisers set a maximum bid for how much they are willing to pay per click. If there is little to no competition for a keyword, you might be able to run ads at very low CPCs, potentially around $0.01 or even lower. However, the actual amount you pay can vary based on your ad's quality score and competition at the time of bidding. Overall, while there isn't a defined minimum, effective bidding strategies are essential for achieving low CPCs
