A semi-dynamic ad structure automatically incorporates a DKI (Dynamic Keyword Insertion) into your ads, while also including a dynamic prefix. This is enabled by selecting the 'Include DKI Prefix' check box in the Ads & Ad-Groups section of the Campaign Builder.
Selecting the 'Include DKI Prefix' check box will automatically select the 'Include DKI' check box as well. By selecting a semi-dynamic ad structure, adCore™ will create several variations of ads depending on the length of your keywords. Using this option will allow you to put a static, or dynamic term before your keyword. Any keyword created by your campaign and placed in your ad must include a prefix.
