Default value for keyword dynamic text parameter to become mandatory soon

We are making a change to the {KeyWord} dynamic text parameter to require specification of a default value. This will be enforced on any new ads or edits to existing ads from October 18^th onwards. Specifying a default value will ensure that your ads will continue to serve if the selected keyword upon substitution ends up extending the ad title beyond the supported limit. Today, the system behavior is that if after keyword substitution, the ad title is too long, the ad will not serve.

 

After October 18^th, if you create a new ad or edit an existing one which does not specify a default value for the keyword text parameter, this will throw a CampaignServiceExpandedTextAdDefaultTextRequiredForKeyword error.
