Include keywords in important places. Include them in your blog post title, the large "headers" introducing a new section, the first few sentences of your post, and in links. Change your settings so each blog post's URL includes the title of the post, not the date it was posted. Try to make these as descriptive as possible to raise your ranking in search results and attract the right audience.
Salaries for bloggers vary widely. This report from Glassdoor shows ranges from $19K to $79K a year for the title "blogger," while other sources say the 14% of bloggers who earn a salary make, on average, $24K a year (or $33K for corporate bloggers). Likewise, freelance bloggers can make anything from under $10 a post to $100 or more for a relatively short post.
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.
Create and customize your blog. If you are using a free service, there should be a tutorial to guide you through the initial steps of setting up your blog, as well as a forum for people to ask questions. If you are hosting your own site, you will need someone with web design experience to customize your blog, or you can use software such as WordPress.org to use the same structures available at free services.
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!
