Publishers are concerned about brand erosion due to unwanted creative being shown to their visitors. For example, obesity ads, adult ads and competitor ads that violate publisher's brand policies. The Blocklist feature in PubMatic helps publishers prevent the display of unwanted creatives to their visitors by blocking the advertiser, advertiser's category, domain URLs and/or creative attributes. Blocklist Manager helps publishers view the domain URLs for an advertiser and then block and unblock accordingly.

Blocklist Manager provides a report of all blocked and available advertisers, advertiser's categories and domain URLs. These reports can be downloaded or e-mailed for future reference.
