By progressing through a literal trial by fire , with my own money and time - I’ve learned a great deal about SEO/SEM and E-Commerce since 2004. This experience led me to agency work with a growing SEO firm, where I’ve touched over 100 different client websites.
Currently I'm the Senior SEO & Internet Marketing Analyst at a well known, Fortune 500 experienced web development firm called X Studios.
Some of my other projects:
Freelancing site for eCommerce consulting is eCommerce Warriors.
At the end of the day, you have to provide value. This is really the best way to think of online business. A blog or shop is just a vehicle for getting your product/service in front of people. It's about finding a need and filling it.
Writing can be great for "service" type income, but eventually writing an informational product that sells over and over again is ideal.
I would focus on integrating your SEO strategy with Social Media and informational "link-bait" tailored for your target market.
Blog commenting can open up relationship opportunities for joint ventures, which can far exceed any back link benefit you see from this activity.
Considering we are at Startup Nation here, bootstrapping is a reasonable way to start a new business.
You can put a plan together and think you have a great idea, but at the end of the day, it's a very good possibility a bank will not lend you money anymore like years ago.
Sometimes the less money you have to invest in your venture, the harder you work to make it happen. Let some time go by, turn a profit, then consider outside financing.
