Google are reconciling the data held on Google Places and Plus to display one set of business data listings.
This means if through happenstance you have multiple listing Google will de-list one and alert you to it.
While this may have initially means your listing has disappeared, ultimately this is very good and means, as usual, that honest business owners can represent themselves fairly.
If you want a pointer on how to resolve your listings don’t hesitate to call us for a free informal chat.
