How to use Google Analytics data to do a Facebook boost in a post ?
Open your Google Analytics account. Look for the date of your last Facebook Boost (if you don't have one, you can check all your data from the start). Sorry for now the text is in French (but you'll figure it our on yours in english with the position)
1- Go to audience and "full audience"
2 - Choose the date (right top of the image) -> in my case 08/08 to 10/08
3- Then go to Demographic Data and full view
In my case, you can see on these 3 days, more than 70% of my viewers were female and about 50 % were between 25-34 years. That's it, i have more or less my last facebook Boost audience.
On the next page i will show you how to do the Facebook Boost using the data we just picked up.
