Publons uses the Web of Science Core Collection — 21,000 journals hand-selected and re-evaluated by expert editors — to calculate citation counts and h-indexes. We do this because we know that every citation we count is derived from a journal that has been vetted by expert editors as meeting the quality standards required to be indexed in the Web of Science.
This means the citation counts on Publons may be lower than e.g. Google Scholar. This is deliberate so that we can track every citation counted back to a known and vetted source.
This does not mean that uncounted citations are all illegitimate, but it does mean you can be sure that no illegitimate citations are ever counted.
