Description: An essential tool for researching audience segments and specific interests usable in Facebook advertising campaigns. It allows you to discover "hidden" interests not immediately visible in the standard Ads Manager.
What is it for? (Practical examples)
This tool is fundamental for those managing advertising campaigns and wishing to optimize their audience targeting.
- Refine targeting: Use it to find very specific or niche interests that are not easily traceable through Facebook's standard ad management interface.
- Potential estimation: Before investing in a campaign, immediately check the estimated audience size for a given interest, ensuring the segment is sufficiently large (or sufficiently narrow) for your goals.
- Market research: Quickly identify topics related to your product or service and compare their audience potential.
Main features
The Facebook Interest Explorer is based on a simple search interface that provides detailed and immediately usable results.
- Keyword search: Enter a keyword (e.g., "Vegan cooking" or "Functional training") to query Facebook's interest database.
- Language filter (Locale): You can specify the language of the audience you are looking for, ensuring the interests found are relevant to your geographic area or target market.
- Audience display: For each interest found, an estimated audience size range is shown (e.g., 1.5M - 2.8M users). This data is sortable to quickly identify the largest segments.
- Deep dive links: Results include quick buttons to perform an immediate search on the specific interest both on Facebook and Google, allowing you to better understand the context and content associated with that interest.
How to use it
The module is straightforward to use and requires no preliminary setup, as it connects directly to Facebook's public targeting data.

Automatic integrations
This tool is designed to facilitate external research and analysis.
- Quick Facebook search: A dedicated button allows you to open a new tab to immediately search the specific interest within Facebook, useful to see which pages or content are associated with that target.
- Quick Google search: A second button directs you to Google for a broader search on the topic, helping you understand the general context of the interest.
