Earning $100 a day from surveys alone is highly unlikely. Survey earnings vary depending on the website, available surveys, and the time and effort invested in. Survey websites typically offer a few daily surveys with low pay, ranging from cents to a few dollars. Therefore, it would take many surveys and significant time to earn $100 in a single day. However, you can increase earnings by combining surveys with other earning opportunities, such as participating in online focus groups, product testing, and freelance work. Additionally, other online earning opportunities, such as affiliate marketing, creating online courses, and selling digital products, can generate higher income than surveys.
