At first glance, the numbers seemed okay. The CTR and CPC were even pretty good compared to what’s usual in the industry. But taking a closer look, there was a big issue. The ads were getting clicks, but not from the right people. They were showing up for searches that weren’t really related to what the company was offering. This mismatch was clear because no one actually took action after clicking the ads, leaving the conversion rate at a worrying zero.
