Perhaps the majority of money making offers on the internet are scams of some sort. Most people who try to make money on the internet fail, the worst may be the surveys, paid to click, shopping rewards thing that I doubt anyone can make a living from. That one fake new blog showing the mom making some $10k part time, used to say posting links for Google before they sued 50 such sites.
If you can write you can find web site article writing freelance jobs that mostly pay $3 to $5 though a writer qualified to write for as an expert for major sites might get more like $10 – $75 per 500 word article.
Someone with unique knowledge might be able to write a blog that eventually, it really has to be an exceptional site with regular new additions to get search engine ranking and enough visitors to earn a bit of advertising revenue. One can start with a free blog host like Blogger.com
A small percentage of people who try affiliate marketing actually succeed, some do quite well, having web development knowledge, sales experience and good management skills would have a better chance.
Many Internet Marketing rookies hang out at Warriorforum.com member written WSO tutorials sell for relatively little money.
I am always suggesting the one looks into freelance marketplace sites as a way to earn money more immediately, these include freelancer.com and odesk.com, while more geared for technicians, you also can find writing projects and simple seo tasks, while there is worldwide competition, a native English writer has a big advantage. One of the easiest to get into is freelancer.com it’s also prone to having lower paying projects and wild west lawlessness, older established sites like elance or vWorker have tighter standards and may have membership fees to keep out the riffraff.
There are also micro task sites that pay small change for a few minutes work, popular with 3rd world countries, some in the U.S. Do them instead of crossword puzzles, the original was created by Amazon, the online store to ‘automate’ tasks a computer couldn’t do, like pick the better of 2 pictures, they named mturk.com after the 18th century Mechanical Turk chess playing machine that had a man hidden inside, shortTask and microworkers have similar micro tasks, some individual jobs are a bit shady, like signing up for product trials, doing surveys, but you get to choose which tasks to perform.
