Microsoft’s Search Funnel Demo is a truly interesting concept for anyone interested in how people search.  I did a output Search Funnel on the word "house" and look what it showed!

You can see the progression of queries that start with "house" and end with "realestate", "houseforsale" and "house tv show".

There’s additional information that explains the chart when you hover over each box above (not shown in my graphic representation). 

You can reverse the funnel and get the words that most commonly end with a search on "home"

It’s going to take me a little time to digest these new demos and what they can do for your search term reseach and copywriting effectiveness.  I think the main issue now is most terms you’d use for targeting are not yet part of this demo, so it’s really more for concept analysis at this point.

But this is where search is going in the future - this is the beginning of the second wave of search tools (away from WordTracker and tools like that which were useful 5 years ago but need to notch it up because Seach is becoming much more sophisticated and mainstream).
