AND and OR conditions

When setting up detailed targeting for Facebook ads (now Meta ads) without using Advantage+, the way you combine keywords and interests affects the breadth or narrowness of your audience:

Detailed Targeting Combinations:

1. OR (Logical Disjunction):
   • Broadens Audience: When you use the OR condition, any of the selected keywords or interests can match. This means that if a user matches at least one of the criteria, they will be included in the audience. This approach broadens the audience since it increases the pool of potential users.
   • Example: If you target “Fitness” OR “Healthy Eating”, your ad will be shown to users interested in either fitness, healthy eating, or both.
2. AND (Logical Conjunction):
   • Narrows Audience: When you use the AND condition, all selected keywords or interests must match. This means that a user must match every criterion specified to be included in the audience. This approach narrows the audience since it decreases the pool of potential users to only those who meet all the criteria.
   • Example: If you target “Fitness” AND “Healthy Eating”, your ad will only be shown to users who are interested in both fitness and healthy eating.

Combining Detailed Targeting Options:

• Default Behavior: By default, when you add multiple interests or behaviors in the detailed targeting section, Facebook treats them as OR conditions. This means that if you add “Travel” and “Photography”, it targets users interested in either travel or photography.
• Narrow Audience Feature: To use the AND condition, you would use the “Narrow Audience” feature in Ads Manager. This allows you to specify additional criteria that users must also match to be included in the audience.
  • Example: First set: “Fitness” OR “Healthy Eating”. Then use “Narrow Audience” to add “Yoga”. This means the user must be interested in either fitness or healthy eating, and also be interested in yoga.

Using Exclusions:

• NOT (Logical Negation): You can exclude certain audiences from your targeting to further refine your audience.
  • Example: Target users interested in “Travel” but exclude those interested in “Business Travel”. This means your ad will reach users who are interested in travel but not specifically in business travel.

Practical Example:

1. Broad Targeting with OR:
   • Interests: “Running” OR “Cycling”
   • Audience includes users interested in either running or cycling, resulting in a larger audience pool.
2. Narrow Targeting with AND:
   • Interests: “Running”
   • Narrow Audience: “Cycling”
   • Audience includes users who are interested in both running and cycling, resulting in a smaller, more focused audience.
3. Exclusion with NOT:
   • Interests: “Running”
   • Exclude: “Marathon Running”
   • Audience includes users interested in running but excludes those specifically interested in marathon running.

By understanding and utilizing these combinations, you can effectively control the size and specificity of your target audience, optimizing your ad campaigns for better performance.
