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.
Affiliate sales comprise a large chunk of revenue for most big-name bloggers. For instance, Pat Flynn made $53K last month from affiliate sales, compared to "just" $9,500 from book sales. In general, look for affiliate products with higher price points; web hosting companies are a great choice if it makes sense in your niche, with payouts of anywhere from $60-$130+ per signup.
I’ve been through quite a lot with my days a blogger. I was making money, but it just wasn’t enough. You literally make pennies and dollars. That is not enough to support yourself. It wasn’t until I met Noah King. A mentor of mine who taught me how to make REAL MONEY online writing about what I love. I am now making $6000/month after a year of hard work and can do it all from the convenience of my home. Never give up or sell yourself short! Noah has his own website where he talks about how to achieve the same success he has. You can check him out here if you’re interested – http://www.deservingwriter.com/
