Patrick Stox provides a summary of the history and evolution of nofollow, ugc, and sponsored attributes. Originally created to combat comment spam, nofollow was overused which led to Google missing 50% of the web. Google introduced ugc and sponsored to better classify links and pass partial ranking signals. Major platforms like WordPress are adopting the new attributes, but widespread adoption may be slow without incentives from Google. Stox provides best practices tips for using the attributes.
