# Hitting audience targets

URL: https://docs.sigment.ai/guides/audience-targets

Iterate analyze → optimize until a creator set reaches a core % and core reach target.

When a brief has targets, such as "at least 7% core audience and 100,000 core reach", use `optimize_selection` (Instagram only, 5 credits). It searches an analysis's already-scraped data for the best subset, so it doesn't scrape again.

1. `create_creator_list` for the brief, so the run always ends with a list.
2. `analyze_creators` with 15–30 candidates, then `wait_for_job`.
3. `optimize_selection(analysis_id, min_core_pct, min_core_reach, max_credits)`. It returns:
   - `current` and `best` sets, and whether the targets are met;
   - the gaps to the targets;
   - `drag_creators`: removing them raises core %;
   - `suggested_additions`: already-scraped creators whose audience overlaps this core.
4. `set_creator_list` with `best` and a description holding its core % and core reach.
5. If the targets aren't met, drop the drag creators, add the suggestions (or `discover_creators` on a narrower subtopic when reach is short) and go back to step 2.

Stop when the targets are met, the budget is spent, or two rounds bring no improvement. The [`hit_audience_targets`](https://docs.sigment.ai/prompts) prompt runs this loop for you.
