One of our best citation building practices is finding already listed listings with correct or incorrect NAPW info and avoids duplications. Then we try to claim it and fix it. If we can’t do that, we try to get it fixed by sending feedback to the site as a non- business owner. If that doesn’t work, we create a new listing with the correct business info, and try to get the old/incorrect one (the listing we couldn’t claim) removed. Note that we aren’t a citation-cleanup service and it’s a one-time payment service (no monthly or annually payment is required).
