If you need to earn extra income online there are a number of ways to do it if you have the right skill sets. Someone who can write articles, design and build websites and can type is often in demand.

People who need to earn extra income online often think that there's nothing they know about related to the internet but if you can use a computer, then there's lots of things you can do.

1. Data entry - dull but it pays the bills.
2. Uploading adverts - as above.
3. Designing and building websites - fun but some minor technical skill needed and/or a knowledge of Wordpress or similar.
4. Keyword research - fun but time consuming and not very lucrative
5. Article writing - interesting and can be well paid if you're someone who can write articles quickly, otherwise, if you get writer's block, you can't get enough written for the pay to be worth while.
6. Affiliate marketing - can be lucrative if you know where to start, what to sell and which market to target.

Affiliate marketing is like having your own business. You choose which products to sell, you decide how to showcase them and you do the advertising for customers. You're your own boss and you can work your own hours which is ideal for people who need to earn extra income online.

There are plenty of products out there to sell from physical products to ebooks. Being an affiliate means that you don't need to keep stock at your home or deal with shipping because that's all done by the company you represent.

Even large companies like Walmart and Amazon use affiliates to sell their products but look around for the ones which pay the best commissions if you need to earn extra income online.
