Why Facebook Ads Haven't Worked For Your Business - Only Using A Single Version Of Your Ad
You should always be running at least two creative variations of an ad against each other to measure the results. You will find on a lot of occasions that just a simple change to an image or line of text can have a huge impact on ad results.
You should always be trying to beat the control and scrapping ads that aren’t producing results to get the lowest possible cost per client possible.
Being efficient with your marketing allows you to either spend more for more leads or spend less for the same amount.
How To Fix This Problem
In the ad level of your ad campaign duplicate your ad and change either the picture or the first line of text and come back in a few days to see which has achieved the best results. Turn off the worse performer and duplicate the best performing ad and make another slight change, and continue the process.
