There are Many Ways to Earn Online
Paid to Post (PTP): This is the first category in my list because I had joined this type of genuine site first. In these types of sites, one has to start a new discussion or comment on an existing discussion. Every site has a minimum number of sentences or characters which you must type in order to get credit. When you start a new discussion, then your earnings will depend upon the number of responses the discussion gets from others.
In case of commenting or respond to others' discussion, you need to get more detailed to get more. So, start a discussion which you think will get more number of responses. In many cases, the responses one get is zero. Try to make referrals, as you will get a portion of your referral's income.
Get Paid to Share files: There are many genuine sites which pay to share files. In these types of sites, one must upload a file (the file can be of any type -doc, pdf, jpg, xls, ppt and so on). The key is that you have to upload your files to the host server and post the links to some sites where you think it will be clicked by others. The most common place is blogs, forums and yahoo answers. There are many people who request for some files, music or videos online. You can upload the requested file by doing some search on net and post the link where necessary. The more the number of downloads the link gets, the more you earn.
Get Paid to Write Articles: On these sites, write articles and see your earnings building up. The more you write, the more you earn. In these types of sites, earnings depend upon the number of visitors to your article. One advantage of these sites is that, your articles quickly get indexed in search engines. So, it is advantageous to write more and more articles, so that after a few days or months, the earnings are automatic.
Get Paid to Click (PTC): These sites consist of some ads which you have to click. Each site has a fixed time for which the ad must remain open. It may be of 30 seconds or so. At a time, more than one ad must not be clicked. In these types of sites, a lot of referrals are required in order to get sufficient amount of money in less time.
Get Paid as a Publisher: Some sites allow showing ads on the publishers' website. The website may be a blog also. To get accepted on these sites, at first make a website or blog and after posting some contents, start promoting it, so that you get a decent amount of traffic on your site. Now apply as a publisher. They will give you some code. When this code is posted on the site, then the ads show up. When someone gets to your site and
clicks on the ads, you get paid.
