YouTube creators will soon be able to link Shorts to other types of content, such as long-form videos. This update will provide a safer way for creators to direct viewers and potentially unlock brand growth and success. Although there are currently no ads on Shorts, linking them to long-form videos can offer an opportunity to monetize the traffic through available ad products. Creators can add a link to their Shorts using a new option in YouTube Studio, and viewers can tap through to the linked content. YouTube announced this link update via its blog and plans to introduce it by the end of September 2023.
