There are some recent changes to Google AdWords that you should know about. Starting July 1st, you won’t be able to edit or reactivate campaigns and ad groups after you’ve removed them. If you’ve removed any campaigns or ad groups that you want to use in the future, you may want to change their status to “Paused” before June 30th.
This is extremely important as this could affect your testing and optimization if you lose a campaign that was removed instead of paused. It is a good idea to reflect on old campaigns to ensure that you are making correct decisions to fully optimize your online marketing. You can only make educated decision by review data and how your campaigns have performed in the past.
