It's important to keep in mind that participants don't "qualify" for all surveys.

Although it differs from spyware, adware often uses the same methods and technologies. Merchants initially were uninformed about adware, what impact it had, and how it could damage their brands. Affiliate marketers became aware of the issue much more quickly, especially because they noticed that adware often overwrites tracking cookies, thus resulting in a decline of commissions. Affiliates not employing adware felt that it was stealing commission from them. Adware often has no valuable purpose and rarely provides any useful content to the user, who is typically unaware that such software is installed on his/her computer.
Just be sure to put a lot of care into your product listings. Everything from the titles you use, to how effective the description is at convincing potential buyers your product is better than the rest, and even taking care to shoot high quality product photos can have a dramatic impact on your sales. I recommend using photo editing tools like Fotor, which gives you the ability to edit your images, create captivating graphic designs and more.
