The Microsoft Ads API has certain restrictions that come in place when using the Ad Text Optimization tool and the Rule Engine for Bing. Among them you might find that:
- If a campaign has no performance data, it will not show up in the Rule Engine reports.
- Entities (like keywords, ads, ad groups, campaigns) will not show in the tool if there is no performance data such as clicks or impressions for them.
Please note that once applied, the changes may take from 20 minutes up to 6 hours to be reflected. This is a restriction placed by the Bing Ads API and not Optmyzr.
