SearchPilot did a study on unique content vs templated content. A customer tested removing their templated content and instead added a block of unique content below the fold of their listing pages.
Removing the templated content and replacing it with unique content resulted in an almost 14% uplift in organic traffic!
It was statistically significant at the 90% level and based on the strength of the hypothesis and size of the uplift, we were comfortable calling this one a winner.
This could have been because we could target more relevant keywords, giving crawlers a better understanding of the page and better match our web pages with users' search queries, or because it improved rankings for more valuable keywords.
