I think one of the best ways to earn extra money online is by taking paid surveys. There are a lot of companies available to choose from if you live in the US, UK, or Canada but if you don't it can sometimes be a bit tricky to find a reputable survey company to earn money with. Here is a list of resources and sites for those interested in taking free online surveys for money but don't happen to live in the US, UK, or Canada.
1. InternetPaidSurveys.com - provides a list of sites that allow international members to join for free..also contains some reviews of survey sites.
2. MySurvey123.com - I really like this site. It has a large free list of US and International survey companies. The forums on MySurvey123 are also a great place to learn about some high paying survey opportunities.
3. WhichSurveys.com - Another site that has a free database listing international paid survey sites.
4. SurveySavvy.com - A survey site that claims to accept member from all countries. I really like SurveySavvy it has a great referral program. You earn $1 for every survey someone you refer completes as well as a $1 for each survey one of their referrals completes.
Remember to research a site before joining. Googling the site name will often provide you with sites that link to either positive or negative reviews of survey sites. SurveyPolice.com is a great resource for anyone that takes paid surveys online and is often a good place to start when researching a survey site.
