HTTPS adoption has more than doubled in the last year, with statistics from BuiltWith and HTTP Archive showing a significant spike in HTTPS sites going from 2.9% to 9.6%, and 5.5% to 12.4%, respectively. This growth is attributed to lower costs, better tools and resources, and carrots such as new web standards, Google's ranking favoritism towards HTTPS websites, and the network effect where one website's actions impact its competitors to transition to HTTPS. The rapid adoption of HTTPS is a positive trend for the web, providing value in terms of security and driving momentum for other security practices.
