YouTube has rolled out a new algorithm that the company says will more accurately reflect YouTube's guidelines for ad-friendly material and result in fewer videos being flagged as advertiser-friendly. "It will supposedly reduce the number of demonetized listings by 30 percent, so 'millions more videos' will be able to make money off the full range of advertisements," reports The Verge. From the report: A YouTube manager writes that the new algorithm was trained by nearly three months' worth of human reviews, starting after YouTube added a manual appeals process for creators in August. Theoretically, this should narrow the range of false positives -- videos that were incorrectly flagged for promoting drug use, using excessive profanity, highlighting gratuitous violence, or otherwise featuring content that advertisers might find objectionable. It's being applied retroactively, so creators who didn't appeal could still get some old videos remonetized. Google also encourages people to keep appealing potentially incorrect flags, because "this updated system is an improvement, but it's not perfect."
