Below is a short list of things you can do to to both increase the number of surveys you are selected for, and to maximise your earnings from each Survey.

Join 20-25 panels, ideally from a mix of subscription only and free-to-join survey sites  It might seem like a lot, but it will keep a steady flow of surveys coming your way.

Fill out all the profile questionnaires. This will allow them to send you targeted surveys you're more likely to qualify for.

During screening questions they usually ask you if you or someone you know works in X, Y or Z industry, always mark "None of the Above" This will prevent you from being disqualified from participating due to a perceived bias.

During screening questions they sometimes ask if you have been involved in any survey about X (Y or Z), always mark "No" or "None of the Above", for the reason above.

When asked if you are the primary decision maker/shopper/etc., say yes. Replying 'no' will nearly always automatically disqualify you from taking part.

Do not choose the "Prefer not to say" option - always try to give an answer.

Always answer consistently during a survey; contradicting yourself does not help!

Respond to invitations frequently to let the panel know you're active and willing to take part.
Don't take too long in completing a survey.

Start a survey A.S.A.P before the quota is reached. This is especially important on surveys with a high payout.

These are just a few of the tips that will help you to get the most of taking paid surveys. As you take more and more surveys, you will gain confidence and knowledge, and find that you're able to answer questions more quickly and effectively. So don't worry if things seem pretty tough or confusing to start with, you'll soon get the hang of it, and remember that the better you become at taking surveys, the more panel opportunities will be offered to you!
