Conversion data tells you which keywords are actually bringing in results, whether that is a sale, a sign-up, or a phone call. When a keyword has many conversions at a low cost, you increase the bid to get more traffic from it. When a keyword spends money but brings no conversions, you lower the bid or remove it. Some marketers use smart bidding strategies like Target CPA, where Google automatically adjusts bids based on what keywords are likely to convert. Without conversion tracking set up properly, none of this is possible. So what do you think is the first thing a marketer should do before making any bid changes?
