Considering I own a website that does review for earning money online, I guess I spend around 6 hours a day working on the website, researching, and writing up reviews. I then need to spend around another 2 hours testing out websites or writing up articles that people have ordered from me. Overall I can spend quite a few hours a day online. I don't do this on a daily basis, but I do need to do this 4 times a week. Otherwise, if I don't my website starts to lose visitor and people don't want to come back if it isn't updated on a regular basis.
