This guide takes you through how to get yourself up and running, so that you can start building your Facebook ad campaigns. We cover:
Setting up a Facebook Business Manager (to manage your Facebook assets)
Adding people to your Business Manager
Setting up a Facebook Ad Account
Setting up a Facebook Page
Assigning assets to people in your Business Manager
Set up a Business Manager account
Head to https://business.facebook.com. Complete your Business profile. From here you will be able to manage all your assets like ad accounts and pages, and also assign permissions on who can access what.

Add People to your Business Manager
Go to https://business.facebook.com/settings/people
Invite people to be added to your Business Manager. Once added, you can assign them to have access to the ad account and Facebook page that you will create.

Create Facebook Ad Account
Now go to https://business.facebook.com/settings/ad-accounts
Click “Add New Ad Accounts”, then click “Create a New Ad Account”

Make sure you add billing details to the account, so that you can run ad campaigns.
Create Facebook Page
https://www.facebook.com/pages/create
Follow the steps through to create your Page. This is the page that will be attached to your Facebook ad campaigns.

Assign assets to people
Got to https://business.facebook.com/settings/ad-accounts, and click “Add People”.
This is where you will assign who has permission to access the ad account.
Now go to: https://business.facebook.com/settings/pages, and Add People to have access to manage and advertise on behalf of this page.
Add your Facebook Pixel to your website
Go to https://business.facebook.com/pixels.
Go to the Actions menu, and click View Pixel Code. Copy and paste your pixel code, and ask your website admin to add it across your website, just before the tag.

You definitely want to get your pixel added to your website as soon as possible. Not only will it enable you to track conversions, but you can also build website custom audiences of people to retarget with your Facebook ads (i.e. retarget people that have visited your website).
