Well, it is. Until you go to your accounts and check for balances. You find you are not making what you thought you would. You may even say "why did I bother."
This is all okay. We all go through this. This is the learn curve. Easy money really only comes after you have the knowledge and experience. Stumble 100 times, hit the big one once.
This is how it worked for me. Follow some rules and facts.
Facts:
1. websites take time to build popularity by search engines.
2. you must Search engine optimize your keywords and content.
3. read, study, learn from others.
4. you don't have to spend a lot of money on promotion.
5. find soild proven programs to build from first, then add your ideas and make it more of your own.
6. most everything is free on the internet, find it!
Rules:
1. The web doesn't care who you are!
2. Search engines only care about the balance between content, keywords, link popularity, traffic, and relevance.
3. 80% of your traffic will come from search engines.
4. it's a numbers game. The more traffic to your site the more likely to convert sales, clicks, and sell advertising space.
5. MORE IS BETTER. Make multiple web sites. Have lot's of content. Link to thousands of sites.
Take all of this and go sign up for Google Adsense and Yahoo Publisher and anyone else you can. You should have multiple rivers of revenue. DON'T put all your eggs in one basket. Having multiple AD revenues will greatly expand your base.
Google pays best right now. Yahoo is good. Affliate programs are subjective. You must fine tune and match relevant content. But they work.
These are the basics. Now go out there and find your niche. Over time you will have built a tiny empire.
