Hi dear I'm Saidul islam, a Digital Marketing Expert. I looked at your KZbin channel. You started the channel in 2015 and have already uploaded over 107 videos. However, you only have 568 subscribers and the videos have very few views. I realised that although your content is great, the videos are not properly SEO and optimised. This has caused your channel to lose rank. I see many more problems. If you allow me, I can advise you in detail on how to fix your channel's problems and reach the content more effectively.
