Blocking a Creative by Keyword

Blocking by keyword enables the publisher to block a URL when the specific URLs for an advertiser is not known. Using this feature, the publisher can specify a keyword which is a part of the advertiser’s URL and the PubMatic system will automatically block the entire list of domain URLs which contain this keyword in it. For example, if you want to block creatives from an advertiser named, "XYZ," and specify the keyword in PubMatic as xyz, all the domain URLs present in the PubMatic system and all the subsequently added domain URLs, which contain xyz will be blocked, such as, and so on.

This feature also continuously checks the system at regular intervals if there are any new domain URLs being used to serve creatives. If such a new URL contains this keyword, then that URL is also automatically blocked. In this way, the publisher does not have to check for new URLs from the blocked advertiser and then block them manually. After adding a new keyword, the publisher can then use this feature to view the list of blocked domain URLs which contain this keyword. This allows the publisher to review and check whether this feature is not accidentally blocking a domain URL due to the presence of the specified keyword. The publisher can then unblock a domain URL which it does not want to block, even though it contains the specified keyword.

The objective of Keywords-based URL Blocking feature is to block the domain URLs automatically by specifying the keyword which appears in the URL name.

If you want to block creative URLs using keywords, you must first add the keyword. Once you add the keyword, the corresponding domain URLs (both currently existing and subsequently added) will be blocked automatically.

Add a Keyword

  1. Select Ad Quality > Creatives and select the Keyword tab.
  2. Specify whether this action should be applied to all sites or a specific site by using the Select Site drop-down list.
  3. In the Enter Keyword box, enter the keyword name that you want to specify.
  4. Click the Add button. The keyword will be specified and the corresponding domain URL(s) will be blocked automatically.
Once you specify the keyword, all the subsequent and existing URLs that contains same keyword will be blocked.
