If you’re testing two headlines and one is pulling more reach and clicks, while the other has a higher CTR and lower CPC, the better performer really depends on your end goal.
If you’re trying to get in front of as many people as possible, the headline with higher reach and volume of clicks might be your winner—it’s casting a wider net.
But if you’re aiming for efficiency and stronger audience response, the one with a higher CTR and cheaper CPC is signaling better relevance and engagement per impression.
In most performance-focused campaigns, especially if budget is a concern, the headline with higher CTR and lower CPC is the stronger contender because it’s giving you more bang for your buck. That said, don’t forget to consider downstream metrics (like leads or purchases) before making your final call.
