Facebook retargeting may be geared towards capturing those who have already visited your site, but this doesn’t mean you can’t still use the retargeting information to build brand awareness by reaching those who haven’t yet heard of you. Advertisers can create “lookalike” audiences based on the data from the Facebook Pixel to create ads geared towards new customers who match the profile of present customers.
Retargeting can help your business and/or product stay relevant while customers may be looking for other options. It’s a great way to give your audience a second, third or even fourth chance to purchase your product. Running Facebook ads can help with the social growth of your business. If you want to be successful at Facebook advertising campaigns, I would suggest starting small. You want to A/B test and measure the results from your ads to find that winning formula that yields success.
