“Google’s algorithm is giving more preference to WordPress powered Content Management Systems (CMS) “, this is false news circulating in the industry for the past few months. As WordPress blogs and CMSs are developed to be very search engine friendly, it is easy for GoogleBot to accept the content. This is the real fact. Google never rank a website or page for the reason it is built in WordPress.
Google’s John Mueller tweeted on this misconception about Google’s Algorithms. He said “WordPress is a great CMS & works well in search, but afaik our algorithms don’t explicitly check for any particular CMS.”
