Google Maps Now Supports Bulk Listing Verification

Until now, business owners who wanted to bulk register multiple business listings at once would have to verify them individually.

There are certain guidelines in order to qualify for the bulk registration process:
1.) Accurate and up-to-date data 2.) Minimum of 10 bulk uploaded listings already in business owners' Local Business Center account 3.) Compliance with Google Local Business Center Quality Guidelines 4.) Submitted by the owner of all businesses listed 5.) All businesses have only been submitted by a single user

Google occasionally reviews its listings and if the listings do not meet their criteria, then the listing get demoted to "unverified."
