There’s a chance you may have missed an update towards the end of last month involving paid and organic reports in AdWords. PLA numbers will no longer be included in the report which means you will only see text-ad data. This won’t mean anything to you if you don’t use paid and organic reports, but if that’s the case then I highly suggest at least trying this report once.
While AdWords does provide great insights through the likes of the search term report for example, this paid and organic report allows you to review how paid ads and organic search results work together, which in turn can help you to identify new and potentially valuable keywords. It also gives you the ability to view how your overall online presence is performing with regards to views and clicks.
The following article in the Help Center explains how to set up the report, understand the data presented to you and also get the best use out of it - http://goo.gl/p9RVBu
