If a Mail.ru advertising campaign's CTR is consistently low despite a high impression count, which element should be the FIRST priority for optimization?

If a Mail.ru advertising campaign has a consistently low Click-Through Rate (CTR) despite a high impression count, the ad creative (including both the ad copy and visual elements) should be the first priority for optimization. CTR, which is the ratio of clicks to impressions, measures how effectively your ad captures the attention of users who see it. A low CTR indicates that, while your ad is being shown to a large audience (high impressions), it is not compelling enough for users to click. Ad creative encompasses the visual elements of the ad, like images or videos, and the text that goes along with it (the ad copy). Optimizing the ad creative means improving the ad's visual appeal and making the ad copy more relevant and engaging to the target audience. For instance, testing different headlines, images, or calls to action can significantly impact CTR. Before modifying targeting parameters or bidding strategies, ensure that the ad itself is optimized to maximize its initial impact on the user. Focusing on the creative elements can yield the quickest and most significant improvement in CTR, as it directly influences a user's decision to interact with the ad.
