Microsoft announced that you can now share negative keyword lists between campaigns in Bing Ads. You can do this with the Bing Ads Editor, the web interface, or the API.
"Gone are the days of manually copying negative keywords between campaigns," says Microsoft's Anar Alimov. "With this release, you can create lists of negative keywords and apply them simultaneously to as many campaigns as you want. You can add up to 5,000 negative keywords per list, and create up to 20 lists per account."
"Associating a negative keyword list does not subtract from that campaign or ad group’s own limit of 10,000 negative keywords (see the table below)," says Alimov. "For example, you can have 10 negative keyword lists with 1,000 negative keywords each, and associate all of those lists with one campaign. The campaign itself can still have an additional 10,000 negative keywords of its own."
Shared lists are only able to be created at the account level and applied to the campaign level. You can use the feature by signing in, clicking the Campaigns tab, and selecting "Shared Library".
Microsoft has a step-by-step guide on how to use the feature here.
