The announcement to make Yahoo! IndexTools a free service, coming so quickly on the heels of the acquisition, would seem to serve notice to Omniture, Google Analytics, and other market leaders, such as Nedstat, Coremetrics', Unica, and WebTrends' about the seriousness of Yahoo!'s intentions.

Eric Peterson has written a very thoughtful post that delves into the market implications on this latest move.

But from a customer perspective, this could become a bit confusing in the short term. According to IndexTool's Dennis Mortensen, current customers were contacted to let them know they'd be able to continue using the service at no cost if they sign forthcoming agreement from Yahoo!. Details about the agreement and how this impacts current customization projects is still being sorted out, as is how long customers will have to determine if they want to accept the terms.

I'm sure most customers will be inclined to sign the agreement to maintain continuity, unless they have concerns about Yahoo! storing their data, as Google stores Google Analytics data.

Is this a founded concern?

It all depends on your privacy policies -- something you should consider in your requirements for a web analytics tool to begin with. If you haven't figured this out, then you should.

My guess is that for most current IndexTools customers, this will not be a show stopper.

If it does present difficulties for your enterprise, now would be the time to review the vendor profiles in the Web Analytics Report.

In the meantime, current IndexTools customers will surely be asking some important questions, like whether all their current functionality will remain available for free, and if so, for how long. Will data from the pre-Yahoo! days still be available? For how long? How will this affect custom work that you're doing or planning have done by IndexTools, as well as whether there will be a new technical and professional service availability and cost structure? And what about new features and releases, such as Rubix; what will be the cost and support structure?

Yahoo! is moving quickly, and I expect that they will seek to address these issues. However, as a customer, you'll have to make sure that you get these and other questions answered completely before signing on the dotted line.
