Agreed. You definitely have to do retargeting campaigns too so you can stay in front of them and help drive them to convert when they are in the consideration phase.
However, if you are bidding on keywords showing purchase intent (usually on Google Adwords), the user's should be more engaged. If the Google PPC traffic isn't engaging you may need to optimize your landing page and do some A/B testing.
Facebook is quite different because the user isn't expressing intent at the time they see your ad (usually interest/demographic based targeting) and are having to jump off FB to check your site out. So your landing page has to be really compelling and quicker to digest for that audience. You have to try and capture an email and drop a FB retargeting pixel for sure.
The strategies should be different based on those channels because of the context and frame of mind the user is in.
