Short answer
On the LinkedIn ABM screen, click Download company list (CSV). The file uses LinkedIn’s headers, companyname and companydomain, in UTF-8. In Campaign Manager, upload it as a company list under Matched Audiences. LinkedIn processes it within 48 hours. Upload a new file when the list changes, because one audience holds one list.
Download
- Open LinkedIn ABM in your dashboard.
- Click Download company list (CSV).
- The file lists every company with ICP fit 60 or more in the selected period.

- In Campaign Manager, open your ad account and go to the audiences section.
- Create an audience from a list upload and choose a company list.
- Upload the CSV and name it, for example “AI-identified ICP companies”.
- Wait for matching (up to 48 hours), then add it to a campaign with job function and seniority.
Tips
- Keep the domain column: it matches better than names alone.
- LinkedIn recommends at least 1,000 companies per list; group small lists into broader campaigns so each audience reaches 300 members.
- Remove customers and open opportunities before uploading.

Questions
Why only ICP companies?
LinkedIn budget is best spent on companies that fit. Send all identified companies only if your ICP is broad.
