1. Stay on Facebook
Many people don’t realize it, but if your ad has a link and that link points off of Facebook (an external link), your ad is going to be more expensive than one that points to somewhere on Facebook (an internal link).
Simple dollars & cents… The longer someone is on Facebook, the more ads Facebook can show them. So if your ad takes someone off Facebook, at least in the short term, it can cost Facebook the chance to lead that same person to another ad.
So what is the alternative?
Well if you are running an ad that would normally go to a landing page built on ClickFunnels or LeadPages, etc. consider using Facebook Lead Form.
Facebook Lead Form will not work for every ad, but if all you are trying to do is collect a person’s contact information, many times it will. Plus, because Facebook will autofill that contact information it tends to be more accurate than information typed in by the visitor.
