FB Algorithm exposed

Key Concepts

• Facebook Ad Serving Algorithm: The system Facebook uses to determine which ads to show to which users.
• Facebook Pixel: A piece of code that tracks user activity on a website and sends data back to Facebook.
• Auction-Based System: Facebook's ad system operates like an auction, where advertisers bid for user attention.
• User Value: The estimated worth of a user to Facebook, often based on their purchasing behavior.
• Ad Quality & Relevance Score: Metrics Facebook uses to assess how relevant and engaging an ad is to users.
• Estimated Action Rate (EAR): Facebook's prediction of how likely a user is to take a desired action (e.g., click, purchase).
• Bid Cap: A maximum amount an advertiser is willing to pay for a specific action.
• Broad Targeting: A strategy of removing all layered targeting (interests, demographics, locations) to allow Facebook's algorithm more freedom.
• Creative as Targeting: The idea that the ad's visual and textual content is now the primary driver of targeting, rather than explicit interest-based selections.

Understanding the Facebook Ad Serving Algorithm

The core of the Facebook ad serving algorithm is an auction-based system where every user has an assigned value, typically determined by their purchasing behavior on the platform. Hundreds of thousands of companies compete daily to reach these users. An advertiser's ranking within this algorithm is determined by a formula that considers:

• Bid: The amount an advertiser is willing to pay.
• Bid Cap (if used): The maximum bid set by the advertiser.
• Ad Quality & Relevance Score: Facebook's assessment of how relevant and engaging the ad is to the target audience.
• Estimated Action Rate (EAR): Facebook's prediction of the likelihood of a user taking a desired action.
• User Value: The estimated worth of the user to Facebook.

The Facebook Pixel and the ad's creative are identified as the primary drivers of ad performance. Facebook's algorithm optimizes towards the specific event an advertiser chooses to optimize for. For instance, optimizing for "purchase" will lead Facebook to find users more likely to buy, while optimizing for "traffic" will focus on users who are more likely to click.

The Power of Data and User Understanding

While conspiracy theories about Facebook listening to conversations exist, the speaker notes anecdotally that ads sometimes appear eerily relevant to recent discussions. The underlying principle is the vast amount of data Facebook possesses and shares. This data allows Facebook to infer user behavior and interests, even without direct input. Examples include seeing ads for furniture after buying a house or seeing shoe ads after being with someone who just bought shoes. This highlights Facebook's ability to leverage location data and social connections to influence ad delivery.

The Shift Towards Broad Targeting and Creative Dominance

A significant argument presented is that interest targeting is dead and is being removed from Facebook. The speaker advocates for buying broad since 2015, which involves removing all layered targeting such as interests, gender, or location. In 2024, the creative is the targeting.

Arguments for Broad Targeting:

• Avoiding Exclusion: Targeting specific demographics or interests can inadvertently exclude potential customers. For example, if a product's core demographic is female, excluding males might prevent them from seeing the product and sharing it with female friends or partners.
• Capturing Incremental Conversions: Even if a primary demographic (e.g., 50+) drives the majority of conversions, excluding younger demographics (e.g., 18-50) could mean missing out on an incremental 20% of potential conversions.

Example of Broad Targeting:

The speaker illustrates how excluding males from an ad campaign for a product with a female core demographic could lead to missed opportunities. Similarly, targeting only individuals over 50 might exclude a significant portion of younger potential buyers who could still convert. The speaker emphasizes that their wife has often sent them ads received on Instagram, demonstrating how ads can reach individuals outside of explicitly defined targeting parameters when a broader approach is taken.

Conclusion and Key Takeaways

The video emphasizes that understanding the Facebook ad serving algorithm, which is an auction-based system driven by user value and advertiser bids, is crucial for success. The Facebook Pixel and the creative are paramount. The speaker strongly advocates for a shift away from traditional interest-based targeting towards broad targeting, arguing that the creative itself now serves as the primary targeting mechanism. This approach allows Facebook's algorithm to identify the most relevant audiences, potentially capturing incremental conversions that might be missed with restrictive targeting. The underlying principle is Facebook's extensive data collection and its ability to infer user behavior and connections.
