How to use this list

Start broad, then narrow

Pair one large interest with a few specific ones so the audience is neither tiny nor generic. The sizes here tell you which is which.

Expand from what already works

Take an interest that converts and search it in the finder — related segments come back with their own sizes, including ones the Ads Manager dropdown never shows.

Check it against live ads

Before you commit budget, see who is already advertising to that audience with Facebook ad spy, and which products they are pushing.

Where the data comes from

Every interest and estimate on this page is read from Meta's Marketing API — the same source Ads Manager reads when you type into Detailed Targeting.

Questions

Is this every interest Facebook has?

No — Meta doesn't publish a complete list, and the catalogue runs well beyond what fits on one page. This is the browsable index by category; for anything not listed, the interest finder queries the API live by keyword.

How do I use one of these in Ads Manager?

Copy the interest name into the Detailed Targeting field when you build an ad set. Names here match what Meta returns, so they resolve to the same segment.

What are hidden interests?

Interests that never surface in the Ads Manager dropdown even though the API returns them. Searching a niche in the interest finder is how you surface those.

Find the interests that never make this page

The finder queries Meta's API by keyword, so you can surface hidden interests for any niche, compare their audience sizes, and export the lot.
