Some online jobs that are legit and that you can do working from home are customer service agent, Administrative Assistant, Video Captioning, transcribing etc.
Other online jobs are Freelancing, blog article writing, type at home jobs, medical billing and coding.
Blogging is another option to make money working from home and is a great online job that allows you to work for yourself and earn money eventually through your own products, advertising, E books affiliate programs etc.
Find a niche that gets a lot of search traffic and look for a blog niche that pays a good amount per click through Adsense.
A friend of mine blogs for a living online and works from home writing blog content for his own blog after 10 years of blogging he's now raking in $10,000.00 per month without having to hardly do any blog writing.
He still blogs now and then to keep the blog traffic up and to add new refreshing content to the blog but now that he's built the blog up he can mostly sit back and relax and make the $10,000.00 per month and he even makes money online while he sleeps.
So blogging can be a great way to make passive income overtime.
