For example, I can see the fastest rising search terms in Los Angeles and Berlin in the past week.

But what I’m finding fun right now is plugging in brand names and seeing where they’re strong. I offer, by way of example, some vehicle brands and maps showing search volume in the United States:

The four-wheel-drive Subaru line is understandably popular in mountainous, cold-weather states:

Saab has some fans in New England, but that’s about it:

Another ailing GM make, Hummer, still gets some interest in Nevada and Texas (I suspect the bump in interest in Michigan may be mostly from concerned GM stakeholders):

Toyota’s Prius, meanwhile, is especially popular in eco-conscious places such as California and Vermont:

And the Vespa scooter craze seems to have taken hold on the West Coast and, inexplicably, Utah:

When you look at popularity over time for all five brands, you can clearly see how interest in the brands associated with fuel-sipping vehicles spikes during periods when fuel prices are high. No huge surprises here, but it’s fun to see how well search data tracks real-world trends.

Byrne: User engagement is how we nurture and build a community. Our reader engagement index is a comments-to-postings measure for a given month: So we will tally how many comments on X number of stories/blog posts that BusinessWeek.com published that month. This gives us a ratio figure that we track to determine our monthly reader engagement index and growth.
