These are some of the easiest and quickest ways to make money online, most of which are the ones I started out with. There will be no survey sites because those are a waste of everyones time, there will be no paid to read sites because those are a waste of time as well. However you will find some affiliate, freelance, and blog/affiliate processes. These have been proven to work, and not just by me, but by many others. Once again (as if I even have to say it) you wont become rich by doing these proceeses unless you find the "golden key". But they will give you enough money to live, or to live modestly, I know because I am living modestly from them!
Domain Parking - I did this a few years back when Arbitrage was permitted, but even though arb isn't allowed any longer, individuals are still creating good money income from these programs. Try places like Sedo, Fabulous and Parked (very highly rated). Since arb isn't allowed any longer it's a good idea to make your domain a parking page if you receive a lot of natural or organic traffic. The steps are very easy. Find a parking program. Sign up. Point your DNS on your registrar from the domain you want to use to the domain parking DNS, set up the colors, templates, themes, keywords, etc. Traffic will get sent to the parking site and YOU will get a share of the profit made from your web site. Take a look at sites that offer 80% or more.
Freelancing - Many individuals online offer some sort of a service or have a specialty they are good at. These people can sell their services online in places such as websites, forums, even by putting an e-mail sig in their email program. In my own experience service forums or forums that allow service providers or have a marketplace which will allow you to make a thread with your shpeel and allow people contact you either through the thread or through PM are the best. This is probably my most winning way of marketing my service, so I seriously suggest you check it out!
CPA Programs - CPA is sometimes referred to as "Cost Per Action", which has to do with the fact that most CPA offers by advertisers are about getting something (typically new customers by making sales). You can normally place CPA codes on your site, which will let you "sell" things from your site. When individuals sign up or buy the item, you will be given a certain percentage from the initial sale. Say you are advertising an e-book on your website and someone clicks the advert and goes to the site, they will buy the e-book for $150 and then you receive 35% of the sale, which means you made $52.50 for just that one sale! These offers add up rather nicely especially if you get in with a CPA program that has high rates.
Ebay & Affiliate Storefronts -
As far as shopfronts go, I actually like Amazon merely because they offer many diverse products on the website. For example, I have a website, so I can go to Amazon and pick out different affiliates that I know that I will be utilizing at my joke site. Affiliates that offer such things as gag gifts, gag gifts, funny gifts, etc. Once I find the affiliates to use I won't only set the affiliate links, but I can also set up affiliate websites. Then, I can either "sneak" in the affiliate links onto my blog, or I can also include the actual mini stores on my blog. This is good because people can visually see what I offer on my site.
Of course like I said above, there are a ton more ways to make money online, but really, if I listed every single way I may as well just write an e-book and sell it (which is another way you can earn residual income for yoursefl)!
