Earm money through survey sites

Joining multiple survey sites is a great way to approach the survey world. Sometimes you will get a survey for a site that you aren't eligible for, so if you have joined multiple survey sites, you're more likely to get a survey you are eligible for each day. If you stick to just one survey site, you won't make as much money if you spread out into various survey sites so that you can participate in more surveys daily.

I have joined a number of survey sites, and I must say it has been very disappointing. Whenever I take a survey, at some point down the way, a message will come up saying that I am not qualified. If I am not qualified, why asked me to take the survey. I am not wasting my time on them any more.

I dont know about the earning stuff but yeah i do know about if someone is taking surveys so those survey sites offers different rewards for the users

There are many survey sites available the best advice I can give is to make sure you log on and check if any surveys available don't wait for a survey invitation. Also make sure you respond quickly to surveys as they'll reach the required number of entries very quick.
