Samira has a travel app named YourAdventure. Why should she create themed ad groups for specific offerings, such as culinary experiences, guided hikes, and architectural tours?

Creating themed ad groups, like "culinary experiences" or "guided hikes," allows Samira to tailor her ad copy and keywords to specific traveler interests. This ensures that when someone searches for "Paris food tours," they see an ad directly relevant to culinary experiences, increasing the likelihood of engagement and conversion. Irrelevant ads are less effective. While bids can be adjusted at the ad group level, the primary purpose of theming is relevance, not solely budget or bid management across interests. Language targeting is a separate setting, not the core function of themed ad groups.
