I have been with GDI for about a year now but only started doing the business since August. This is a business and needs to be treated like a business. Don't work for 1 month and say, "I didn't get anyone, this doesn't work". Be consistent and persistent. Work 1-2 hours a day at least 5 days a week and you will see results. Come on people, where else can you have your own business, a global one, for only $10 a month??
Total agreement here. I have been here for 4 months and it's only now starting to take off. There is a lot to learn. The above post neglected to mention creative advertising on social networks. There are many out there but you have to avoid writing things that sound to "spammy". Offer the service because many other providers have down time or limits which I have not encountered with GDI. And my site has never been down or "exceeded bandwidth" limits. The service is excellent!
Blogs and commenting Blogs has worked wonders for me. Other tips below.
