Google has updated its reviews policy to add two items; (1) do not have your staff solicit a certain number of reviews and (2) the content of the review should not mention the staff member's name and information.
This update was added to this section of the user generated review policy. Here are the lines added:
Merchants requesting that staff solicit a certain number of reviews
Merchants requesting that staff solicit reviews that include specific content, including content that identifies a staff member.
Amy Toman spotted this change and posted about it on LinkedIn - she wrote, "I expect they've seen too many review contests or requirements." Sounds like it. "Be sure to update your staff on this; don't want your reviews being filtered even more than they are currently," she added.
