I have an AdWords account, which was set to use Auto-tagging of URLs.

When looking at the Analytics account for that site, I couldn't find any reference to AdWords traffic either in the Advertising section or the Traffic Sources section.

So I manually constructed the URL tags, and updated the Campaign Ad. Once the ad was approved and the clicks started coming through again, I could see the results in the Traffic Sources section of Analytics. In the Sources > Campaigns section, my campaign was listed, and under Sources > All Traffic, it was registering the same level of traffic from google/adwords.

However, the Advertising > AdWords section is still drawing a blank. Any ideas? Are there explicit steps needed to enable full tracking of AdWords campaigns?

If it is relevant, the Adwords campaign was set up with one account, and the Analytics tracking with another, but both accounts have full access to both AdWords and Analytics.
