How good are your planning skills? Would you be prepared to put your money where your mouse is and buy shares in a company that you identified as a good investment prospect?

I doubt that many people would. But this could be the outcome of a project driven by Google Insight. Wikinut founder Andy Walton posted a comment about his experiment after I blogged about the application of Google Insight to identify the likely success of a campaign.

Walton’s contention is that Google Insights can be used to link search volumes to product usage and revenue for brands that [are] unique enough to avoid cross over with unrelated searches.

“The ability to query Google’s massive store of historical search query information offers many possibilities, one of which is accurate prediction of online company revenues,” he says.

Walton has compared the historical revenues for Bwin against search volumes since 2004 and with the exception of one year has found a correlation. He has used this match to predict the likely outcome for 2009.

“The 2009 prediction is showing -7%, indicating a tough year for Bwin, which is a bold prediction given at the third quarter mark they were 3.5% ahead of 2008,” said Walton.

We’ll have to wait until Bwin announces its results in April to find out if his methodology stacks.
