Just of recent paid advert as dominated my mind and I want to fully take advantage of it. As a result of this, I've been exploring different advertising strategies to create a cover profitable campaign. I came across the concept of retargeting during the cause of my research about page ads. I was thinking that does retargeting cost less than regular advertising? With what I mean it seems that retargeting often leads to better conversion rates. It is said that it reduce the overall cost per acquisition compared to cold advertising.  With all of these, I imagine the cost-effectiveness depends on the platform and audience size. 

Has anyone here had experience with retargeting? Did you find it cheaper and more effective than standard advertising campaigns? I Would like to hear your insights!
