There are the typical tactics on YouTube of enticing titles, eye-catching thumbnails, and of course important keywords at the beginning of all 3 sections (title, description and tags), but YouTube is going to highly value how long someone stays watching your video (and keeps watching more videos because of it) so you'll want to ensure your content is resonating with viewers and keeping them engaged.

I took a look at your website and noticed that you give a call to action to subscribe to your YouTube channel at the end of the post, but don't actually link to the channel or mention it's name. How are people supposed to know how to do that? You need to make it very easy for them.

Your accent is also very heavy making it difficult for others who don't share that accent to understand you, so I would highly recommend adding captions. I noticed in the video that you embedded from Facebook that the captions were not enabled. Captions are also used by YouTube as metadata to help know what your video is about, which will be especially useful in your case as their automatic captioning system will likely not do very well with your accent.

Happy to offer more advice through a call!
