Key Citations are the most valuable citation sites and data aggregators and the most important sites to be listed on.
We gather these by determining which sites have the biggest online presence and high Domain Authority. To calculate what is classed as a Key Citation we look at a number of different factors but primarily focus on the number of pages indexed by search engines like Google.
We provide a different list of 'Key Citations' for each country as this differs. (Citation Tracker currently covers the US, the UK, Canada, Australia, New Zealand, Ireland, Philippines, Macau, Taiwan, and Hong Kong.)
