The only other way you can earn in One Poll is through their referral program. However what you earn off your referrals depends on how active they are in the site. For example, you’ll be rewarded with £0.50 for every referral you make. However, if your referral makes £20.00, One Poll rewards you with £1.00; and if your referral makes £40.00, you’ll be rewarded with £2.50. Some problems with the referral program is that you can only refer 10 persons, and you can refer persons only through email.
InboxDollars pays anywhere from $0.50 to $5.00 per survey on average, and they can take anywhere from 3 minutes to 25 minutes to complete. However, some online surveys pay $20 or more if you qualify. Be sure to complete your profile survey. That way, you maximize your chances of getting high-value surveys that pay a more significant amount of money. 
All this website is great but one site which is not mention here is univoxcommunity.com. i am attached with this site from last 2 years and i have earned many points and 2 Amazon gift card. got amazon gift card , which operates across the world and gives you access to millions of products!. and they are very friendly with panelists. i love this website which always ready to help in any trouble. so for me this is my favorite site for earning money.
I don’t see PaidViewpoint on your list. I like using that site. I signed up for it on June 28, 2016, but I guess I forgot about the site and stopped using it on July 24, 2016 but had a total of $1.91. I started using it again on May 5, 2018, and I’m now up to $27.05 and have a trait score of 10, which is the highest. The surveys are easy and you don’t get disqualified. I mostly earn 10 cents, but once in awhile I earn some good money like 62 cents. It does take awhile to add up, but it’s free money.

this company stole my credits or rather disappeared them when they deleted my account in January saying I was not active for 6 months when I was currently active in doing offers. Customer service is a joke they speak broken English for 1 and 2 they have no access to any information for your account or the company. those same people are the ones who would talk to the better business bureau when you complained that they will not give you the credits that they owe you.
