SEO is quite easy...provided you have time. I wished I heard about that word when I first came to UK when I have loads of time in my hand.
I am working full time now so just touching and promoting my site every now and then.
The best way to make money on internet (billionaire/millionaire status) is to create a site of your own.
Others can work on articles but as I am not a native english speaker, it will take me time to create an article. I just outsorce on someone to do my articles for $1=100 words. Obviously he's American...cheap english labour.
Once he write articles, I just use thebestspinner when I have time. I'm a bit too lazy because I got to the first page with the keywords that I like.
One trick is to use bookmarking demon to bookmark articles (not directly on my site) because it may get penalized. It can also cause problem as it uses my IP address, private IP address is another cost and I don't want to have problem my IP address.
I mainly submit at squidoo because one submission and it's done. Hubpages is too much hard work for me in maintaining a score of 75? can't remember.
If I were in the Philippines, I could have done SEO more as it can earn me dollars/pounds but not now as I am earning the same anyway.
By the way, are signature links allowed in this forum?
