When clicks are coming in but nothing is converting, the landing page is almost always the first place to look. The ad brought the person in, which means the message worked, but something on the page made them leave without acting. Check if the page loads fast, if the offer is clear, and if there is a simple action for the visitor to take, like a button or a form. Also check if the page matches what the ad said. If the ad promised a discount but the page does not mention it, visitors feel misled and leave. What do you usually check first when a campaign gets clicks but no conversions?
