I cannot find where to create an ad group. I created a campaign but cannot find any links for creating ad groups. Also, the Ad groups tab is missing when I log in. On the Google's support page, it says: On the All online campaigns page, click the name of the ad campaign that will contain your new ad group. Click the + New ad group link that is just above the buttons at the top of the ad group table. I cannot find any of these pages or links. Did Google discontinue ad groups or are they still available? Edit: Never mind, creating a new campaign allows me to create ad groups. I think they changed the interface.
Don't know if you figured this one out, but I saw that no-one had replied so thought I'd offer help. Basically, if you click on the name of your campaign on the left hand side of the Google Adwords interface, you should see the information relating to that campaign in the main body of the page. There are 5 tabs: 'Ad Groups', 'Settings', 'Ads', 'Keywords', and 'Networks' If you highlight the Ad groups tab, you'll see a button below that says 'New Ad Group' click that and it will start the process for you. Hope that helps.
