They fetch the contents from other Web sites and encourage their users to share their preferences on what they like and see all over the Internet with their friends.
They're not social networks per say because people aren't directly in contact with each other, only through their shared contents.

The net profit margin, or simply net margin, measures how much net income or profit is generated as a percentage of revenue.
It is the ratio of net profits to revenues for a company or business segment. Net profit margin is typically expressed as a percentage but can also be represented in decimal form.
<h3>How do we calculate net profit margin?</h3>
Net profit margin is calculated by dividing the net profits by net sales, or by dividing the net income by revenue realized over a given time period.
<h3>What is good net profit ratio?</h3>
For example, in the retail industry, a good net profit ratio might be between 0.5% and 3.5%.
