Let's talk about how to make money online without money...
Also better way is to have enough money to get domain so you'll look more professional. Domains are pretty cheap these days almost every place has under 10$/year. But you don't have to atleast not just yet. You can start up with Blogger which is free and supports advertising too and it's very easy to get work with AdSense ( it's googles own advertising site ) which pays per clicks and its the most popular among every blogger.

This is how i started just few days ago:
- I Registered this blog at http://www.blogger.com
- I got Domain from GoDaddy (https://www.godaddy.com)
- I configured to get my blogger URL to show as www.mytuonela.org
- I registered these sites on the right (you'll get to these sites by clicking icons)
- And after that I've been doing research about these things and still learning
- I'm blogging what I've learned and I'm going to update with all new info what i get.

Anyways I'll try to post you more tomorrow so just wait a bit longer.
Thanks.
