CTR manipulation involves changing certain aspects of a link or ad so as to increase its click through rate. In addition, try leveraging personalization & segmentation strategies when creating ads for maximum efficiency! You could target audiences based on their past behavior (on social media platforms) or by selecting keywords relevant to their interests. For example, if one particular ad significantly out-performed its competitors after being run for some time, then this could suggest that its content was particularly well received by viewers and thus should be used in future campaigns as well.
