What are 'Key Citations' in Citation Tracker and how are they gathered?

Key Citations are the most valuable citation sites and data aggregators — they are the most important sites to be listed on.
 

We gather Key Citations by determining which sites have the biggest online presence and high Domain Authority. A number of different factors are considered, in order to calculate what is classed as a Key Citation, but we 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 following 10 countries:

• The US
• The UK
• Canada
• Australia
• New Zealand
• Ireland
• Philippines
• Macau
• Taiwan
• Hong Kong
