There is no one-size-fits-all answer to this question, as the potential earnings generated by blogging will vary depending on the type and nature of the blog, as well as the skills and experience of the blogger. However, generally speaking, it is possible for blogging to be a passive income source.
One key factor that will determine how much money a blogger can make from blogging is the frequency and quality of their content. If a blog is regularly publishing high-quality articles that attract a large audience, then they may be able to generate a significant amount of revenue through advertising and affiliate links.
Additionally, if a blog has an established following, they may be able to generate revenue through book sales, speaking engagements, and other forms of endorsement.
However, it is not necessary for a blogger to generate huge amounts of revenue in order to make a living from blogging. Even modestly successful blogs can generate a decent amount of income over time if they are regularly publishing quality content.
In fact, many bloggers make their primary income from blogging through advertising and affiliate links rather than through direct revenue generation.
So overall, it is possible for blogging to be a passive income source. However, it will largely depend on the type and quality of the content that is being published on the blog, as well as the skills and experience of the blogger.
