La herramienta antiguamente conocida como Campaign Negative Sites y renombrada a Site exclusion tool ha sido actualizada para permitir hasta 500 sitios negativos donde no publicar tus anuncios de Adwords.

Según informan en el blog de Adwords:

Recently, we increased the number of sites that you can exclude using this tool to 500. This gives you the ability to further tailor your AdWords account to the needs of your business. Remember, excluding a site in the content network will prevent you from showing on all of the pages that fall under that site’s domain.
