What it does

Builds a Meta retargeting audience from ENGAGEMENT instead of website traffic: people who watched a video, interacted with a Facebook Page or Instagram profile, or opened a lead form. NO PIXEL AND NO WEBSITE TRAFFIC NEEDED, which makes it the only realistic retargeting option for accounts with a small or brand-new site (and the best lookalike seed you can get early on).

source: video | page | ig | lead_form source_id: the video id (list_meta_page_posts), page id (list_meta_pages), Instagram account id, or lead form id. event (optional, sensible default per source): • video → ThruPlay | 10s | 25% | 50% | 75% | 100% (Meta has no 95% threshold) • page → page_engaged | page_visited | page_messaged | page_cta_clicked | post_engaged • ig → ig_business_profile_engaged | ig_business_profile_visited | ig_business_profile_all • lead_form → lead_form_opened | lead_form_submitted | lead_form_not_submitted retention_days: 1-365 (how long someone stays in the audience). confirm=false previews.

How to use it

You don't call tools by name. Write what you want in ChatGPT, Claude or another assistant connected to Opus Growth, in your own words; it picks this tool when it fits.

Because this tool changes your account, your assistant first shows a preview of exactly what will change. Nothing is applied until you say yes, and every applied change is written to your audit log.
