Behind Google Ads, Facebook Ads is 2nd largest ads platform in the world.
Facebook Ads allows advertisers to reach users across all of Facebookās main properties; Facebook itself, Instagram, Messenger and (soon) WhatsApp.
Facebook Ads lets advertisers target users using a variety of methods.
These range from the broad and benign, like targeting people in North America aged between 18 and 45, to the granular and precise, like targeting parents of newborns who also own a pet cat.
The range of targeting options available to advertisers has changed frequently throughout the years, at times increasing and at others reducing.
More recently, Facebook appears to have been cutting down on certain targeting options that pose too much of a threat to user privacy.
While Facebookās actions have trended in the direction of removing options for precise micro-targeting, a wealth of options still remain for advertisers.
One lesser-known option is the ability to target people who are members of specific groups, or who like specific Facebook pages.
Cue LeadEnforce
Facebook itself doesnāt offer these targeting options, but they are available via third party tools such asĀ LeadEnforce.
LeadEnforce offers advertisers the ability to pick specific Facebook groups or pages whose fans they want to target.
LeadEnforce will then pull together an audience of all of the people they can find who are members of that group, or who like the relevant page. This audience is then shared with the advertiser so that they can use it to target their ads.
You Can Tell a Lot from The Pages You Follow
The usage examples on LeadEnforceās site are fairly mundane. They suggest how a car dealer could target a fictional āCar Salesā group in order to find potential customers. Or how someone (I donāt know who) could target a group called āContent-marketingā in order to find, I guess, content marketers.
The first time I actually came across LeadEnforce I thought it was an interesting idea, but quickly moved on. It wasnāt until a month or two later that I realised how much personal information can be gleamed about someone by knowing what groups they belong to, or which pages they like.
If you wanted to target people affected by cancer, you could target the 34,821 members ofĀ Cancer Survivors & Supporters. If you wanted to exclude LGBTQ people from seeing your ads, you could use LeadEnforce to build an audience of people who likeĀ LGBTQ Nation, and tell Facebook not to show ads to them.
With all the scrutiny that Facebook has come under in recent years for its role in elections, itās particularly notable that you could use LeadEnforce to target sensitive political groups. If the UK conservative party wanted to suppress the Labour vote amongst Jews, they could create an audience from the 49,123 people who likeĀ Campaign Against Antisemitism, and show them ads to invoke fears of antisemitism in the Labour party.
My Trial with LeadEnforce
To test if LeadEnforce would actually allow me to do the things above, I created a trial account with them. I input the URL for the Campaign Against Antisemitism Facebook group into LeadEnforce, and less than an hour later it had successfully managed to find details for 13,313 of the people who liked the page.
LeadEnforce let me see ages, genders, locations, relationship statuses, education and employer details for these members. LeadEnforce didnāt give me the names of individuals, but it did give me their initials:
Iāve blurred the initials and locations, for (hopefully) obvious reasons.
I then wanted to see what the process was like for actually getting this data into a Facebook Ads account, to see how easy it would be to target this audience.
To do so I had to accept LeadEnforceāsĀ Marketing Agreement. There was nothing in the agreement that appeared to prevent me from using the tool to create any of the audiences mentioned above.
Once Iād accepted this, I was able to share the audience Iād built to a freshly-created Facebook Ads account, and start running ads targeted to the audience almost immediately. For obvious reasons, I didnāt actually run any ads.
I was however able to put everything in place so that I was just a switch of a flick away from showing ads to 13,313 people who liked theĀ Campaign Against AntisemitismĀ Facebook page.
It doesnāt appear that this was a one-off either, or that LeadEnforce had restrictions on what audiences I could or couldnāt build. I was also able to build audiences of people whoād likedĀ LGBTQ Nation, and members of bothĀ Cancer Survivors & SupportersĀ andĀ UK Muslim Group.
To Wrap Up
Iām not suggesting for a minute that LeadEnforce has any customers who use the tool to target audiences like those mentioned above, nor am I suggesting that they have ever had such customers.
What my trial with LeadEnforce showed though is that itās a powerful tool, one which is capable of doing much more than the Facebook Ads platform allows on its own.
If a bad actor were to use LeadEnforce to target any of the audiences Iāve outlined above, itās believable that their doing so could go wholly undetected.
And in a world of high-stakes elections, and where social media knows more about us than our partners, thatās a scary thought.
