What is a Cornerstone Content?
Cornerstone content refers to the most important content on your site. These contents are crucial as they serve as gateways to the other content on your site.
Cornerstone content generally ranks for highly competitive keywords. These keywords are, in many cases, the exact keywords you want your site to rank for.
For this reason, cornerstone contents are usually in-depth and authoritative. They are also frequently updated to improve their rankings and ensure they don’t get outranked by other content.
