Reputation Management uses Best Match to determine if the listing found on a source belongs to the business entered. You can read more about Best Match here.
If you've just created a new listing on a site, Reputation Management should pull it in on its next search. Alternately, you can add it to Reputation Management manually by selecting View Possible Matches under each site and then pasting the URL of your listing. After submitting this link, it may take up to 48 hours for the listing to appear in your Listings list.
It is also possible that we are experiencing issues with a specific source. When a listing source updates their website, there are often changes we need to make on our end to accommodate them. Until the changes have been made on our end, we often pause a source until we are able to do so. Please take a look at our Disruption Notices to see if there are current issues with any sources.
