Category: Report mobile apps impressions based on over 30 genres such as Business, Entertainment, Finance, Food & Drink, Health & Fitness, Music & Audio, News & Magazines, Social, Sports, and Travel. The data is available for apps that self-report to the relevant app stores.

Sub-Category: There is a new set of categories that are based on app store-provided second-level categories. (Note that this information is limited to apps that provide second-level categories, such as Mobile Apps > Mobile Games Apps > Adventure Games.)

Mobile Brand Safety (Negative Apps): Sometimes,mobile apps contain content that is not safe to your brand. However, the content advisory rating offered by app stores is often inaccurate and can result in flagging perfectly safe apps as unsafe. SAS uses all obtainable data about each app, including the name and description, to accurately differentiate apps that are safe from the ones that are negative, which may threaten your brand's safety.

Mobile Fraud: The SAS Verification Mobile Fraudulent Apps category is based on a statistical algorithm that analyses traffic patterns and flags apps with suspicious traffic patterns or volume. The data is combined with blacklists of known fraudulent apps, and apps that were tested and found to feature malicious activities (for example, sending ad server calls while not active).

User Rating: This category is based on user-reported experience, such as stars.

Popularity: This category classifies apps into four levels. You can verify the number of impressions from mobile apps according to these popularity levels:

Content Advisory: You can verify if your impressions from mobile apps were safe based on teh following maturity categories:

Price: You can report your impressions against price-related categories, free apps (no in-app purchases), paid apps, or apps with in-app purchases (only on Google Play).

Uncertified Apps: Uncertified Apps is a category that identifies mobile app traffic from Android and iOS devices that do not come from any app in the Google Play or Apple Store. Rather, they are usually side-loaded into the device by using direct download or by installing an alternative app store. These apps represent roughly 10% of all mobile app traffic.

Though from a consumer perspective, these apps fall into various categories like Torrents and Games. Research into the nature of the ad traffic that they generate has found a very high incidence of fraud. For example, these apps continue to make ad calls after the user closed the app, make ad calls but never display any ad to the user, or freeze the device completely.

Language Categories: allow for reporting based on recognition of 35 different languages.
