You cannot change your campaign to a new campaign type once it's been created. If you want to adjust where your ads can appear, create a new campaign using a different campaign type.
For Search, Video, and Shopping campaigns, change your campaignâs "Networks" settings, which also affects where your ad can appear. For example, you can enable your Search campaign to show ads on the Display Network.
