Google announced both on Twitter and in its forums that it will notify customers or users who leave reviews on Google Local results after owners respond to their reviews. Marissa Nordahl, community manager at Google My Business, said: When businesses respond to, or update responses to customer reviews, the customer now receives an email notification. The business’s response is published immediately and 5 minutes later, the notification is sent. This 5 minute delay allows time for the merchant to make any corrections to their response after submitting. The notification email informs the customer of a reply to their review, and contains a link to a page with the full owner response. Note: The review response is published immediately on Search and Maps. Get the full story at Search Engine Land
