Another (perhaps less “conspiratorial”) thought that occurred to me about why Google removed phone numbers from the 7 Pack is to address the SEO + call tracking data quality issues that have been discussed in a number of recent posts on this blog:
Perhaps Google is trying to prevent call-tracking numbers from being exposed in the 7-Pack. Though in a way that doesn’t entirely make sense either. Google said to me that it’s using call tracking numbers (via Google Voice) for its Local Listing Ads.
I’m eager to see what the company says about all this.
