If you are really looking forward to learning bookkeeping then I think YouTube and Google will be enough for you but if you are looking forward to making a career in it then you should definitely go with proper certification. But it doesn’t matter whether you learn from YouTube or Google, you must use cloud accounting for bookkeeping.
There are many ways to learn Bookkeeping, for example, Youtube, Udemy, blogs, and Facebook Groups and online paid courses. I don't suggest you go online for paid courses when freeways are available.
I suggest you join Facebook Groups like 5 Minute Bookkeeping by Veronica Wasek. She is a QuickBooks online trainer. Here tutorials are available on Youtube, Facebook Group, and on is website 5mb Academy.
