Say I mad a custom audience on May 4th for people who visited a certain product the last 3 days and used it for a campaign. On May 10 I decided to use the same custom audience above for another campaign. Will Facebook target people who visited my website the 3 days preceding May 10th? Or the 3 days preceding May 4th.
