The previous writeup of Google Correlate as a competitive intelligence tool focused on the correlation of search with uploaded data, or with other searches. That blog post concluded that Google Correlate is not very useful for competitive intelligence, because of its inflexibility.
Google Correlate also has a fun feature that lets you draw a curve in your browser, and Google will find a search term whose historical trend matches that curve most closely. Can this feature be used for competitive intelligence?
Say, for examle, that you are looking for a competitor in decline, and draw the following curve:
Google will work out that this curve is most similar to that of the search history for "hp 3500":
Similarly, you might search for a phoenix-like resurrection from the dead, and turn up the following search history for "AT&T Messaging":
And you might uncover the rise and fall of "Sharepoint services":
These are all interesting trivia, but even if they were genuinely useful, it is unlikely that such competitive intelligence will coincide serendipitously with a competitor you are actively tracking at the time.
So, again, Google Correlate may be fun at times, but is not a g ood tool to use for competitive intelligence.
