Hi Sam! I love your site. We should definitely connect. I’m a school counselor and recently launched a site for parents to address pertinent teen topics. Like you, I struggle with the ultimate service I’d eventually offer on my site, but Ramsay’s idea is a great start. He’s absolutely right that people are looking for fresh content for their sites! Best of luck to you and I hope we can collaborate.
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.
If you’ve spent a lot of time writing that week and just need a break from working on a post, it may be a productive way to spend an hour or two but I personally think your time could be better spent elsewhere. (This isn’t to say that you can’t find success utilizing this method, I just don’t see many/any people doing it and reporting back that it’s really helped them).
Have in-depth knowledge in your niche? Package it up into an ebook and sell it on your blog. I'd generally advise against selling it (at least exclusively) on Amazon or Kobo, as you'll probably be able to charge much less. If you've already built up a solid audience, you can probably change anywhere from $5 for a very short one, all the way up to $39+.
Google Blogger supports advertising through Google AdSense, PayPal links, and limited affiliate links. If you use excessive affiliate links, fail to add relevant content when including affiliate links, or get paid to increase someone's search engine ranking, Google will move your blog much lower in the search rankings, greatly decreasing your audience traffic.
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!
