YouTube has announced changes to its system classifying videos' suitability for advertising, promising creators that less of their uploads will now be limited or barred from monetisation.

The video service has been working on its technology since damaging reports early in 2017 about prominent brands' ads appearing next to unsuitable content.

However, some creators have complained that their videos have been unfairly flagged, reducing their income in the process. The most recent example was vlogger Casey Neistat, who published a widely-shared video criticising YouTube after his latest video was demonetised by the system.

YouTube's latest update offers more encouraging news for its channel owners. "Since August, over a million human reviews have helped train and improve this technology and today, we’re releasing an important update that will result in fewer misclassifications overall," explained the company on its support forum.

"As a result, there will be a 30 percent reduction in the number of videos receiving limited ads as they move to being fully monetised. In other words, millions more videos will become fully monetised."

Few if any YouTubers depend entirely on the platform's ads for their income, so even demonetised videos can still play a role in making them more appealing to brands for influencer-marketing campaigns. Still, news that YouTube's classification filters are getting more efficient will be welcome news for creators.
