The lack of YouTube viewers

Recently I saw a bit of an uptick in the number of followers in my YouTube channel but the number of viewers is still very low.

So I was wondering, why do I have so few viewers on my videos and so few subscribers on my YouTube channels?

I started to put together a list of potential reasons. Once I have a list I should try to understand which one can be fixed and which one can have the biggest impact on the channel.

• Lack of focus? That I have videos on at least 3 languages.
• Thumbnails not very inviting.
• Titles not very inviting.
• Lack of keywords.
• Lack of consistency in publication schedule.
• Content not interesting enough.
• Presentation is not nice (e.g. lack of editing, text size, lack of focusing on the code).
• My accent in English.
