Why don't I see any suggestions in the Negative Keyword Finder (Search) tool?

This optimization analyzes individual words from the search terms report that have not converted to find potential negative keywords. You may not see suggestions in this optimization because of one of the following reasons:

The search terms that have not converted may have received very little traffic. The system usually requires a minimum threshold to make recommendations. For example, you won't see search terms that have 1 impression and 1 click in the list. To remove the traffic threshold and to see all suggestions, enable the Turbo Mode.
The optimization only analyzes search terms from search campaigns and not shopping campaigns. If the account has only shopping campaigns or display campaigns, you won't see suggestions.
The optimization doesn't show suggestions that are already present as negative keywords in the account.

Why don't I see the negative keywords applied through the Negative Keyword Finder (Search) in a campaign?

The Negative Keyword Finder (Search) only adds the keywords to shared negative lists. You can confirm the same in your Google Ads account under "Shared Library" as shown in the screenshot attached. If the negative keywords that were added through the optimization don't show up in the shared negative list they were added in, please contact us at support@optmyzr.com.

I seem to be getting the same suggestions every time I run Negative Keyword Finder (Search) in a workout

This issue is usually caused if the shared negative list is an MCC level shared list. Shared Lists at the MCC level are not supported by the API, so, unfortunately, we are not able to detect it.

Our suggested workaround for these cases are

1. Creating a new list at the account level

2. Downloading the results as CSV and uploading them using Google Ads Editor.

I'm getting an error when adding negatives to an MCC-level shared negative list

Currently, the Google Ads API doesn't let us write to MCC-level shared negative lists. We are working on a workaround, but in the meantime, you can add the changes to a shared negative list that is specific to an account.
