and publish it to one of Google's platforms, including Google Opinion Rewards. When users take a survey using Google Opinion Rewards, their answers are combined with the large pool of other respondents and shared with the market researcher. The respondents' demographics including age, gender and geographic location are inferred based on "anonymous browsing history and IP address" or taken from the demographics questions asked when setting up user account. App monetization Users can earn from $0.10 to $1 for each survey. A minimum of $2 must be earned to be eligible to receive rewards. Apple users can cash out the value of their earnings to their PayPal account. Android users can transfer the value of their earnings into Google Play credits to purchase other apps from the Google Play Store. These apps include digital books, TV shows, movies, games, and apps. Credits can also be used to make in-app purchases. If Android users want to exchange Google Play credits to cash, they can do so externally through third party apps that can exchange the google play credits to PayPal for a percentage of their earnings. The rewards must be redeemed within one year from the date received, or else they will expire. Criticism Google Opinion Rewards offers benefits to both the surveyor and surveyee. The surveyor benefits from the large pool of surveyees achieved through the financial incentive and the wide demographic available online, in addition to the fast return of results, cost effective price and convenient surveying methodology. The surveyee benefits from the rewards offered in exchange for their time and opinion. However, online surveys have also sparked criticism due to highlighted concerns. The two common concerns regarding Google Opinion Rewards include the privacy and security of surveyee information and the validity of results. Validity of results The validity of results produced is a major concern regarding online surveys. Google Surveys have been designed on a "quick, inexpensive surveying" model compared to traditional interview or paper methods. However, this quick and efficient method to increase the sample size raises the concern of validity, as people are perceived to not pay attention when partaking in an online survey. This is known as 'inattentive response behavior', 'satisficing behavior' or 'careless responding'. In addition to the suspected satisficing and forging of data for financial reward, surveyors have been critical of the program's 'random' sampling methodology or rather the lack thereof.
