Well, in 2010 I was doing affiliate marketing via Facebook & Adwords. FB made some changes during that time that made it impossible for me to continue. I ran with Adwords for a while but then Google killed of the niche too. This is basically what happens when you trust your livelihood in the hands of other companies that can turn it all off in a second. The income that year was split in half between me and my partner so in total I think we pulled in 300k. It was nice while it lasted but then the real world knocked.
2009 - 0 (moved and was living off savings, almost broke)
2010 - 150k (affiliate marketing, self, from home, 3 hours per day worked)
2011 - 24k (just a sliver of affiliate marketing, self, from home, not sure how many hours I worked)
2012 - 42k (SEO contract work, tiny company - part remote, 40 hours a week)
2013 - 42k (SEO contract work, tiny company - part remote, 40 hours a week)
2014 - 55k (marketing at small company - remote, 40 hours a week)
2015 - 75k + fully paid top tier health plan (marketing - large ecommerce company - remote, 40 hours a week)
2016 - 50k (freelance - from home, 20 hours a week)
2017 - 60k (freelance - from home, 20 hours a week)
2018 - Looks to be on track to 100k (consulting - from home, 5-8 hours a week)
For context, 2009 - 2015 I was living in a high cost of living location. Today I live in a very low cost of living location.
