Does Conversion Optimizer Account for Match Type

[The Adwortiser]

Help Center says Conversion Optimizer accounts for Time of Day and Geography and Day of Week but does it account for Match Type?

Another way of asking is should i use all 3 match types in my campaigns with Conversion Optimizer enabled?

Yes conversion optimizer uses all variables available within your account. It watches the performance of each keyword (including match type) and makes adjustments.

SO yes you should be using all 3 match types, a good list of negative keywords to prevent unwanted ad impressions/clicks and then an ad group with exact, another with phrase and one more ad group with broad.
