41. Find something that won't sell, let your imagination run wild. Be willing to think the most outrageous thoughts, the most impossible items to sell. Who would have guessed there'd be an active market for urine. Yes, that stuff you flush away. No, I'm not taking the ... mikey. Start selling your outrageous item and you may find that a market already exists. You can also sell your hair, your blood, your eggs, breast milk and body parts... and rent your uterus.

42. Build a community. While some webmasters see lower returns from forum-type sites it's probably because they're using contextual programs like Adsense. One of the biggest webmaster communities (forum) is free to join and free to use though it's very busy, uses massive bandwidth and costs its owner a bomb. Yet, he makes a very profitable income from organising conferences/tradeshows. His "community" ensures every one is a sell-out.

43. Be a link monkey. Webmasters want people to link to them. It makes them feel loved. And it helps them rank higher with search engines. But they don't have the time to go begging. You do that for them and get paid per link. If you're smart you'll find shortcuts and charge people a lot of money for identifying and approaching possible link "partners".

44. Related to the link idea above - start a directory submission service. There are lots of directories around like the ODP. Many take free submissions but you have to do these by hand. When you're familiar with the submission process at a few of the top ones it takes you a lot less time to make submissions. Webmasters have to register, wait for a reply, jump through other hoops etc. They'd rather outsource it to someone who can do it faster and has the time.

45. Another flavour of link-building: Dropping mention of your client's site in forums, blog comments etc. Yes, clients pay for it. There are spamming ways of doing it and some more decent ways. If you can make relevant posts, posts that contribute to the discussion and provide only those links that are beneficial to that thread, you'll be in high demand with webmasters looking to spread the word about their good content. For example, if you genuinely feel that this list of 101 ways to make money is the dog's testicles - and you participate a lot in webmaster forums - you're bound to come across threads where dropping a link would help your forum mates. Some website owners pay for that.

46. Press release websites often need people to screen user submitted releases for profanity etc., before running the "news". Well known blogs often require the same kind of vetting service for user submitted comments to blog articles. Niche directories that take automated submissions need to prevent against SPAM so could use a human review of each submission. There are numerous such opportunities. Spamming site owners with offers of your service may not get you anywhere. The key is to identify a site that looks like it could use this service and make a personal approach.

47. Write an ebook. It's as easy as falling off a chair. Know something about something? Whether it's about growing cabbages, writing PERL, plucking nose hair or being a good cop - if you're a good marketer, or pay a good marketer, you can probably sell a few thousand copies of your ebook. People pay online and download it, no publisher, printer, book shop or other cumbersome details to worry about. In fact, you don't even need to do the selling. "Affiliates" do it for you (on commission). And, there are ebooks telling you how you can write and sell ... ebooks!

48. Become an expert in a particular niche, perhaps affiliate programs for kids' products, or mailing list services ..and charge for your advice either at online webinars ... or even at local business events. The great news is that this is the internet and becoming an expert in a niche often requires nothing more than spending lots of time (online) reading and absorbing. No school to attend, no fees to pay.

49. Data sorting and other mundane jobs usually pay by the hour. This is the online version of envelope stuffing except that there really are opportunities to do these jobs online. It's a matter of looking in the right places and avoiding all those scammers looking to part you from your money by asking for upfront fees.

50. Good at graphic design? Design and offer logos and icons downloadable for free (and without watermark on payment of a fee). Good icons sell for several hundred dollars a set. And each set can be sold again and again.
