Author for high domain authority site uses keyword text on author bio to game Google for incredibly rare long-tail terms. Gets nice looking search result pages for said terms, densely packed with their own articles. But... doesn't try it with short tail terms or any terms that people might actually be searching for. This is what happens when you have enough authority to Google and search for terms pretty much ONLY seen together on your author bio. It's funny but it's working pretty much as intended. If it worked for actual, real, current, popular terms then it'd be an exploit. As it stands it's just shitty clickbait.
