Current Facebook Advertising Agent for a large online Real Estate Educator in the United States. (For 3+ years now)
FreeLance Advertiser for small business', both online business and good ol Brick & Mortar.
I've been advertising using Facebook ads for over 3 years now, and have been on the cutting edge of it's updates over the past 12 months, and using it to bring in new customers for business' every day.
Good Questions - If you have no idea what to do to start with FB ads, i would suggest getting on the phone with someone who knows the layout of the system, and how to access all the specifics of FB's targeting system.
You could spend a lot of money really quickly if you don't know what you're doing. And little friendly guidance can go a lot way - and then if you decide it's not for you to keep trying it, finding a FB ad Manager would be the next best step!
Hope this helps!
