For example people create youtube channels where they upload videos about cooking lessons, educational videos, etc.Yes you can definitely earn money using blogging or vlogging. You need to link Google adsense account to your blog or youtube channel for that. Only thing which you should be aware of is that you should not copy content from somewhere else on the internet and add it to your blog or download someones video and upload it to your channel. All content in your blog or youtube channel should be created by you. Also dont click on ads shown on your blog or youtube channel on your own otherwise your Google adsense account will be disabled forever and you wont earn any money.
