Scrubbing is when an advertiser doesn’t pay for invalid or duplicate leads. For example, while a publisher might have generated 100 raw sign-ups to a campaign, 10 were already in the advertiser’s database and 10 more contained bad data. So out of those 100 sign-ups, 80 were valid leads and 20 were scrubbed. Shaving is when an advertiser doesn’t pay for leads that would otherwise be valid but is attempting to increase their profit on a campaign. Dynu In Media does not accept advertiser lead shaving.
