During the Drupal 7 era, we created tutorials on a variety of topics such as Views, Drush, Form API, and theming. When Drupal 8 was released, we updated this content for Drupal 8, 9, and 10. The significant changes between Drupal 7 and modern versions necessitated maintaining two versions of each tutorial on our site: one for legacy Drupal and another for modern Drupal.
Today, we still maintain both versions. The use of our legacy Drupal content has steadily decreased, yet it still has a substantial presence in search results. This often leads to confusion, especially when members trying to learn about features in modern Drupal find themselves on a legacy Drupal tutorial.
In this article, Joe Shindelar writes about his coding experiments to tune search results on Drupalize.Me to favor Drupal 10 content, and demote Drupal 7 content.
