Make sure it’s easy to share your content – I love sharing posts on social media, but it gets frustrating when some blogs make it more difficult than it needs to be. You should always make sure it’s easy for readers to share your content. This might mean making your social media icons easy to find, having all of the info input that is needed for sharing (title, link, and your username), and so on. Also, you should make sure that when someone clicks on one of your sharing icons the title isn’t in CAPS (I’ve seen this too many times). No one wants to share a blog post when it sounds like you’re screaming at them.
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).
PS: my answer to this question is always… “the better question is… how can my blog help me build a profitable business?” Most of the profits from blogging are not made on your blog, but that’s okay. I don’t believe blogging about making money per se, but about branding yourself and positioning yourself within your niche market as an authority and leader. Once that is established, there are so many ways to move people into your money making enterprises. Email marketing, as you pointed out, is one of the best ways to do this. Sending people to your membership sites, services, info products and coaching programs are all great things to route people into as well.
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!
