what is the best way of creating ads in yahoo?for eg if i want create same/similar ads for a lot of ad groups..how do i go about it? do i get into each ad group and then create an ad for that ad group and repeat this process for other ad groups?or is thr a simpler way? i'm new to yahoo...so pardon me if the answer to this is "too obvious"! don't have to go through any of this in adwords! thanks!
Easiest way is to download campaigns, make edits in spreadsheet and then import. Just make sure to follow the import guidelines and to input the correct campaign and ad group IDs in appropriate columns or else you'll come back with errors. If you don't have the import feature in your account, just send the spreadsheet to Yahoo and ask them to upload it for you.
There is also a move ad group function within each ad group's settings tab, which allows you to move and/or copy entire ad groups to another campaign.
