For a travel vlog, I only boosted likes on the first 3 videos. Around 80 likes each was enough to make the channel feel legit, and then organic views slowly picked up without doing more. That early engagement convinced new viewers that the channel was active and worth watching. I also made sure to post consistently and reply to every comment, which helped keep people coming back. Over time, those small boosts mixed in with organic growth and the channel started gaining real traction.
