I had a great time reading this entire post. Specially the story of your grandfather. I think the bottom line of any online business is how well your convertion ratio is. After doing all the basics of SEO ( On Page & Off Page ) its all about converting your visitors into lead customers and that is what matters most in any form of business.

Getting business is what takes you to the next level of competition and eventually establishing a successful business.

Looking forward to more great articles from you.
