Re: diable automatic match
I'm not quite sure what you're asking, but I assume you mean the "close variant" matching where search queries close to your keywords (maybe spelled wrong or including a city-name in the search query) are used to trigger your ads?
As far as I know, you can no longer "turn off" that kind of matching.
What you can do, if necessary, is identify which of these "close variants" you do not want used to trigger your ads and include these as negative keywords in your campaign.
If this does not answer your question, please post again and give more details about your question.
