Some people make gobs of money using a blog. But I'll be honest with you, it's not for the beginner who just clicked fr. Blogging takes dedicated effort that not everyone can spend. Blogging is for those who are okay starting out slow and building up slow.
And I'll be honest here, I could make a ton of money recommending blog software to you such as Wealthy Affiliate, but I need to sleep at night. Some of you might have heard of Wealthy Affiliate through....a blogger blogging about Wealthy Affiliate who is reviewing websites (for example like this one 
)
The way to make money, though, with Wealthy Affiliate is by selling Wealthy Affiliate, not by blogging. A few Google searches may reveal to you that Wealthy Affiliate hasn't really updated their courses in awhile. It's 2023, not 2019. Enough said!
Now, I'm NOT saying don't blog at all.
If you have a huge passion for a topic and you know in your gut that you're going to turn that passion into money earned, then blogging is for you and your blog can also double as your business website and landing page. There are tons of free information and paid but super affordable online courses that will deliver high quality training such as SkillShare or Udemy.
