Is This Tactic Safe for Long-term Growth?

The ?sub_confirmation=1 subscribe link simply triggers YouTube’s native subscribe prompt—it doesn’t automate or manipulate subscriptions, so it’s fully compliant with YouTube’s terms of service. It enhances user experience by making the subscribe action more accessible. For long-term growth, combine this tactic with consistent, valuable content and targeted promotions (like Gleam campaigns) to build a loyal audience.
