Campaign A's objective is driving website visits. Which of these metrics is the most meaningful for this type of campaign?

Click-Through Rate (CTR) is the most meaningful metric for a campaign focused on driving website visits because it directly measures the percentage of people who saw your ad and clicked on it to visit your website. A higher CTR indicates that your ad creative and targeting are effective at enticing users to take the desired action. Follower Growth is irrelevant as it measures audience size on the platform, not website traffic. Impressions count how many times your ad was displayed, but not whether anyone engaged with it. Reach counts the unique number of people who saw your ad, but again, doesn't indicate engagement or website visits.
