Backlinks Guides

A backlink is any link from another site to yours, and the count is the number Moz has found in its index. Counts differ between tools because every tool crawls a different slice of the web. These guides cover how to read the number.

• Backlinks vs referring domains

  Backlinks count every individual link to your site. Referring domains count the unique sites those links come from. Referring domains is the more meaningful number.
