with Custom Audience on Facebook
Advertising on social networking sites is taking giant strides. Despite this impressive
advancement, several brands and marketers are still facing difficulties to find the right audiences,
particularly on Facebook, the web’s most effective advertising platform currently. But, with the
introduction of Custom Audiences, Facebook has offered advertisers a very powerful marketing
tool. Custom Audience on Facebook allows advertisers to target their ads to users through
email IDs, phone numbers or Facebook user ID. Isn’t that something?
And, just in case you have missed this, here’s a complete guide to custom audience on
Facebook, steps to help you create custom audience and its benefits to marketers.
What is Custom Audience on Facebook?
Marketers can target their ads to a specific set of Facebook users using their Email IDs,
Facebook IDs, phone numbers or application IDs.
Like the term suggests, custom audience is a set of people who are ‘customized’ to view your
ads. On Facebook, being able to ‘customize’ your audience means that Marketers can target
their ads to a specific set of Facebook users using their Email IDs, Facebook IDs, phone numbers
or application IDs.

2. This is how Custom Audience on Facebook works
Let me explain this to you with this image below:
Like you see in the image below…
a. You have a database of User ids of your existing customers.
b. You upload this list as a CSV or TXT file onto Facebook.
c. Facebook hashes (secures and encrypts) and matches this data against the data that
Facebook already has. How? Most people use their personal ids to log into Facebook.
d. User IDs that match from your database and the database that Facebook has, you get your
Custom Audience.
(I know, some of the above mentioned terms may sound high tech, fret not! I have explained the
entire process in detail below).

3. Very briefly, what is hashing?
Hashing is a way to secure information and compress it. Like Wikipedia puts it, hashing maps
data of variable length to data of a fixed length. In short, hashing is used to get short output data
that acts as a shortened reference to the original data. It also secures the data and makes it
‘private’.
You need not worry about privacy, the user ids, email addresses/phone numbers are hashed or
encrypted before being sent to Facebook.
However, here are the rules that you need to follow before setting your custom audience on
Facebook.
How to Create a Custom Audience on Facebook?
Step 1: When you go to your Facebook’s Ad Manager, on the left hand side you will find the
‘Power Editor’ tab. If Power Editor has not been installed on your computer, you will see this
window wherein you will be asked to Download it.
Step 2: In order to set your custom audience, you have to have knowledge of Power Editor,
Facebook’s bulk ad editing too.

4. If you don’t know how to operate Facebook Power Editor, here’s a guide.
Step 3: Within Power Editor, you will find a Create Audience tab. Click on that to begin the
process of creating your Custom Audience. When you click on the Custom Audience tab, you
will be asked to accept the terms and conditions. Click on ‘Accept’ to take the next step.

5. Step 4: Next, name your audience and add a description (keep the name and description as
close as possible to your campaign to prevent confusion later). Select a file from your computer
– email addresses, phone numbers or Facebook ID’s and upload it. (Make sure that it is a CSV or
TXT file with only one column).
Step 5: Facebook will hash the audience list which you have provided to the existing profiles.
(this number can be lower than your original list because some people may not be highly active
users or some may not be using the same email id/phone number that you have provided).
Step 6: Once the file has been uploaded successfully, click on ‘Create’ button to create your
custom audience. This can take a really long time, so be patient. You will see the following
message.

6. Step 7: Once your file has been uploaded, your campaign status will show ‘Ready’.
Step 8: Okay, now that your Custom Audience is ready, lets put it to use in an ad! Click on the
Audience button on your left hand corner. You will see this window. Like any other Facebook
ad targeting, give a name to your ad, add a specific location, age and interests of your target
group. After all the filters have been set, the number you see on the right (highlighted in red) will
be your target group.
Step 9: For further targeting, click on the Advanced Options tab under Audience. You will see
the following screen. Choose your custom audience from the lists that you have uploaded. These
are the people who will be able to view your ad. The next column is that of ‘Excluded
audiences’.

7. Step 10: Once you have accomplished all the steps, you are good to go!
How can Custom Audience on Facebook be beneficial to marketers?
There may be many people who are already your existing customers or may
have already purchased the product that you are placing an ad for, why
would you want to show them your ad? Hence, if you put them in the
‘Excluded Audiences’ category, Facebook will refrain from serving them
your ad. This saves you from shelling out more money in PPC ads.
This one is pretty obvious, isn’t it? Now that you can target offline

increase once they see your ads.
Say you are a business which collects email addresses for lead generation.
Why not upload them on Facebook as your Custom Audience? You can then
serve your ads to this set of people who are more likely to convert.Here is
an example: Lets say you have a list of students who have purchased
Physics study modules from you. Now, you have launched a new product

which is study modules on Chemistry. Create an ad on Facebook to target

people who have purchased the Physics modules and alert them of the study
material on Chemistry. The people who have already purchased Physics
need not be your Facebook fans, they already trust your product. Hence,
they are more likely to convert than any other user.
If you send newsletters to customers on a regular basis, extract the email of

8. group as your Custom Audience. You can then serve ads promoting your
newsletter and how useful it is to those customers.
Since this is a new addition to Facebook’s targeting options, the more number of times you upload your user list, the more
people you gather in your custom audience list. So, say for example, you upload a list of 5000 user Ids. The first time you
upload it onto Facebook, you see that Facebook has been able to match say 1200 User IDs. When you upload it once
again, Facebook matches 2200 User IDs and this goes on and on each time you upload the file. However, we are not yet
sure as to how many times you can upload the file onto Facebook.
