Every piece of information about companies on WikiRate must have a source (metric data points and notes for example). Sources can be CSR reports, news articles and so on, which link to web pages, files that you upload, or reports that you write on the platform.

WikiRate has a voting system to assess sources' credibility - vote up or down according to how credible you find a source to be. When assessing the credibility of a source, consider who has produced it and whether they have a good or bad track record of reliable, unbiased reporting, and the strength of the evidence which the source presents.
