I want to create a copy of existing campaign. Can I do that using any tool or Adwords Editor? If yes, How? Please Guide.
Yes .. you can copy or move Keywords and Ad Text to another ad group in different campaign using Google Adwords Tools. Tools >> Modify Your Campaigns >> Copy or Move Keywords and Ad Text
For this, I need to have Ad Group then only I can move Keywords into that. Is there any option to create replica of an existing Campaign?
Simply download your account in adwords editor. click the campaign tab, select the campaign you wish to copy...press ctrl+c, now go to the account where you need to copy this campaign and press ctrl+v... you are done.
You can aslo do this when you start a new camp. the system asks you if you want to copy any other camp.
This way I copied a Campaign and a Ad Group but what if I want to copy all the Ad groups of one campaign to another campaign.
