Personally, I like Benchmarking. It may not provide actionable info but it's a nice little data set to show to my clients. Makes them appreciate my work. I would like to see Google be much more specific as to industry categories. A comparison of the Pet industry or Construction/Maintenance was the closest match to my dog kennel fencing client as I could find. As far as comparing similar sized sites, what's the metric used...page views, $$$, visits???

I must admit, I hadn't considered the more devious potential of Google using conversion results for a quality score. But, don't they have all that info already? The only thing we're agreeing to by opting in is to anonomously share the info so Google can tabulate aggregate statistics, right?
