So here's how you go about it.
1. Design the campaign based on what it needs to convey to the intended target audience.
E.g. Buy a coffee and bring this included bar-code for a free muffin.
External content can also be leveraged here with hyperlinks to: additional pictures, videos or posts.
Now you can utilise the Ads Manager function that will allow you to deliver that same message to specific locations. Alternatively this can also be accomplished via the Create Campaign function under Business Manger.
This will drive you to another display with various options to select from. For this example, the best option is the first, Boost Your Posts. Make a selection from the sidebar to choose preferred campaign objectives.
Name your campaign as a matter of Standard Operating Procedure and then click on the Set Audience Option to proceed.
2. Decide on Your Targeted Audience
Here you make a conscious decision on who will see the ad based on location. The:
More Demographics Options allows for example you to target Workers by Employer name, Job title, industry or office type making it a simple matter to precisely control who will see the ad.
3. Set a Budget
As is the case with Adwords or any other digital advertising option setting a realistic budget is an important step. You can set the daily budget and the number of days that it will run for. So for example if you set a $3 per day budget to begin with for 7 days you know ahead of time that it will cost you $21 for the week to assess how effective this type of advertising is for you.
Additionally Facebook provide the option of naming the ad so that in a setting of multiple ads for that campaign where AB Testing is happening, it will be simple to assess the relative success of each individual ad.
4. Write the Ad
