On rare occasions, algorithms can negate search terms that impact good-performing keywords. For example, the negative algorithms may negate "spatula-turner" (with a hyphen) with 100 clicks with 0 orders. However, this may stop traffic from going to performing keywords such as "spatula turner" (without a hyphen). A possible solution is to whitelist keywords like "spatula-turner" so that it doesn't get negated and ends up impacting essential keywords. ![whitelist](https://cdn.document360.io/f0238742-849b-4f29-9812-9b4fe8e273b6/Images/Documentation/whitelist.png)
