I've just launched a service to generate reaction selfies for YouTube thumbnails and I would love to hear your opinion about the idea. I've read that showing your reaction face on Youtube is a proven strategy to increase CTR and I saw many Youtubers jumping on that trend. And I heard that having to take selfies of yourself for every video is quite annoying so that's why I decided to launch this service. You can generate 20 reactions with different emotions in just 1 click. What do you think about this concept? Do you have any ideas about how I could promote it?
