Heya,
If anyone is doing decent volumes (over $1 million) advertising on LinkedIn, I'd love to talk and share experiences! We are looking to expand this channel significantly over the next few months.
PM me if you are interested in comparing notes.
$1 million per month or per year? Per month, I'm assuming.
I've only dabbled a little bit with LinkedIn so would be of no help, sadly, but I'd be interested to hear if anyone else is having better results!
