# bing_add_negative_keywords

> Add negative keywords to an owned campaign or ad group. A write tool that previews before it changes anything, one of 47 Microsoft Advertising tools…

[Documentation](https://www.getmcpads.com/docs) / [Sources](https://www.getmcpads.com/docs/sources) / [Microsoft Advertising](https://www.getmcpads.com/docs/sources/bing-ads)

Add negative keywords to an owned campaign or ad group. Exact or Phrase match only. Preview by default; existing negatives are kept.

> **Note** Connect through Microsoft, then explicitly select the advertising accounts your assistant may access. Reads are available on Free; writes require an eligible paid plan.

> **Warning** This tool changes the account. It is absent from the tool list on the Free plan, and it previews by default: without `confirm: true` it describes the change and applies nothing.
