Making money through blogging requires a carefully thought out topic. If you have an existing blog with a small audience, be honest when considering whether the topic has broad appeal that isn't already covered by other established bloggers. If it does, great! Otherwise, there's nothing wrong with starting a second blog that will be more successful in attracting an audience, marketing itself, and making money through a variety of methods described below.
The easiest PPC method to get started with is Google AdSense. However, in order to make any kind of decent money with display ads, you’ll need quite a bit of traffic. And by the time you get that much traffic, you’ll make more money going with an ad management company like Mediavine (minimum of 25,000 monthly impressions) or AdThrive (minimum of 100,000 monthly pageviews).
A blog itself isn't really a business—it's more of a platform for other income streams. Your content alone won't likely make you money. Instead, you'll have to get advertisers, sell services like consulting or speaking, use affiliate marketing to get a percentage of sales from links people click on your blog, or maybe offer products like ebooks or premium content to actually generate income. ProBlogger has an excellent post about these different ways you can make money.
To all the bloggers out there…STOP sucking up to the very small, elite and narcissistic group of self-proclaimed influencers out there. If you all stop treating them like they’re special, they will not longer by special and therefore some of us who aren’t in there secret society will be seen as knowing what we’re talking about too! This isn’t High School, grow up and read someone else’s blog already!
