Hi Crisanac, welcome to GDI and the forums.
There are so many ways to improve and increase your GDI business. You are right, there is a ton of information out there. And many many ways to market. Here is a bit of advice. As you learn how to market and you discover all the different methods there are, pick only 2-3 methods and stick with those. Research all you can on those methods. And keep doing them until you start getting results and have mastered them.
Virtually all marketing methods out there work. The trick is learning how to do them properly and then following with daily consistent action. Do them everyday, because nothing you do will bring instant results. But, the more you do it the better you get and the stronger it becomes. It's like stacking pieces of paper one on the other in order to create a tower. One piece of paper is not very high. But if you keep stacking one piece of paper onto another eventually you will look at it one day and it will be very tall. Do you see what I'm saying here?
With that said, you wanted simple and specific instructions to start your GDI business going. Here is something anyone and everyone can do. Get yourself some business cards. You can use the ones from your GDI back office, these are really nice. You can also order them from places like VistaPrint for very cheap. Then get in the habit of placing a card in all the places you visit. When you go out to eat leave one along with your tip. Leave one on the counter of stores. Leave one in a taxi when you reach your destination. Put them in hotel drawers. Just, everywhere you go, leave behind a card. It will become habit in no time.
One of the biggest things that separates people who get results and people who do not are the habits they form. Get in the habit of doing things productive to your business. They don't have to be big, they build over time. Just keep doing them.
Another thing you can do is join some forums and read/post in them every day. Then, in your signature include a link to your GDI page. It may say something like, "Got Dot? Why Not?" or "Build A New Life" or "Go Global. It Only Makes Sense." Put whatever you like, just be sure to be active in those forums every day. Don't over do it. Start with just a few forums then once a month or so add another. Remember, your work builds over time, it's the daily action that really matters.
You might also consider creating a blog. It's best if you don't use a free blog site, create your very own. One you control completely. Then just talk about what you did that day to grow your business. What you learned that day about marketing. Make some videos and just speak about what you experience in GDI and the marketing world. When you get a sign-up, definitely talk about that and how it made you feel. What your hopes are. Things like that. Blogs are very popular and if you post at least 3 times a week you will slowly start to draw attention.
Finally, to keep this short (because there are literally hundreds of things you can be doing) go out and get some training on building a business. Take a look at people like Mike Dillard and watch their free videos and if you have the money, buy some of their ebooks and materials. Because the more you know, the more you can share, the more value you have to other people and the more they will want to be around you and listen to what you say.
Hope this helped a bit. Feel free to contact me if you have questions or write them in the forum and let everyone benefit with what you are learning or trying to learn.
Best of luck! And happy New Year!
