Is re-marketing more effective than initial marketing? (Virtual/Real world)

Re-marketing gives you two advantages if you use it well.First, it gives you follow up exposures. There's research that many prospects need to hear a message many times before they act. Re-targeting puts your message specifically in front of people who've searched it out in the past.Second.

re-targeted ads cost less than the initial ad, generally10% to50% of the initial spend. So you can get multiple exposures at a low cost. So your total ad spend falls (per sale) as the mix of your ad buys shift toward lower cost re-marketing ads.
