keyword match type change history question

[Susie Zhao]

Will the keyword_id change if the match type of the keyword changes?

And does Google Maintain the keyword attribute changing history in AdGroupCriterion?

[Danial Klimkin]

Hello Susie,

Keywords are immutable, so you can't change the match type, you can only remove a keyword and add a new one. So this will be reflected as these two changes in the history.
