Ask HN: Have you tried Facebook advertising?
To be honest I was really disappointed. I expected a higher CTR (more like 0.01 or 0.02%) and a lower cost/click. It cost me nearly $1/click while I counted on $0.25~0.50/click.
I'm planning to use Facebook advertising again though, the geographic targeting is pretty good. Looking for some tips. Should I go for a higher frequency (Seth Godin says that frequency > reach in his book Permission Marketing)?
