Your customer has launched an ad campaign. You want to find relevant keywords targeted by his competitor but not your customer. Which tool can help you do this?

The Keyword Gap tool is designed to compare keyword profiles of up to five competitors, including your own domain. It allows you to identify keywords that your competitors rank for, but your domain does not, or vice versa. This is precisely what's needed to find keywords targeted by a competitor but not by your customer. The Keyword Magic Tool helps generate new keyword ideas and analyze their metrics, but it doesn't directly compare domains. Keyword Manager is for organizing and tracking selected keywords, not for competitor analysis. This can definitely be done using Semrush.
