Google's "Retail Knowledge Center"
Google has published a Retail Knowledge Center that aims to offer up tips and advice for people either considering using Adwords or already enrolled in the program.
Sure, there are some decent tips here but nothing that you can't find on any blog anywhere else on the Web. If you have been using Adwords, you probably already know most of what's in there. From my seat, it looks like one giant, multi-tiered ad for Adwords. There are plenty of links to sign up for the program, along with some articles touting the need for Adwords.
Not that Google should be concerned about declining Adword usage, the recent grumblings around the 'Net aside, Adwords is alive and well and Google's earnings are rock-solid.
