To find Facebook interest targeting with Claude or ChatGPT, give the assistant a topic and it searches Meta's targeting options. PaidSync.ai returns valid interest, behaviour and demographic IDs. Only IDs Meta returns are valid in an ad set, so searching first avoids an error later.
Detailed targeting is built from interests, behaviours and demographics. Each has its own search:
search_fb_interests searches interests by keyword and returns valid IDs and names.search_fb_behaviors browses behaviour segments such as purchase behaviour and device usage.search_fb_demographics browses life events, industries, income and family status segments.All three tools only read.
| Tool | What it needs |
|---|---|
| search_fb_interests | Reads only. A search word. Optional: a limit. |
| search_fb_behaviors | Reads only. Optional: a search word and a limit. |
| search_fb_demographics | Reads only. Optional: a category, a search word and a limit. |
Meta removes or renames segments over time. Use IDs from a fresh search rather than an old list.
These steps use Claude. PaidSync.ai also works in ChatGPT, so you can find Facebook interest targeting there with the same prompts.
