The citation counts displayed on Publons are the number of citations a publication has received from the Web of Science Core Collection.
Here are a few reasons why you may be missing citations:
1. Your publication record has not been linked to a corresponding Web of Science publication record
If your publication has a dash "-" for a citation count, this means the publication record on Publons has not been linked to any publication record indexed in Web of Science and thus we cannot display a citation count for this publication record.
If you know that your publication has been indexed in Web of Science, you can trigger an update by entering its DOI or Accession Number in the URL.
2. Your citation count is yet to be updated on Web of Science
If your publication is showing a citation count but you know there are more Web of Science Core Collection citations for your publication, you may submit a data change request here: https://support.clarivate.com/ScientificandAcademicResearch/s/datachanges?language=en_US
3. The citations you are missing are not from publications indexed in the Web of Science Core Collection
Please note that we currently only count citations that are from publications indexed in the Web of Science Core Collection.
