SDK data is derived by downloading the app's Android APK or iOS IPA file and unzipped. We then check the app's data for SDK signatures in paths, AndroidManifest.xml and the Info.plist. Many apps are unable to be zipped. Downloading and opening the APK or IPA takes time and resources thus the smaller totals.

App-ads.txt files are an open standard by the IAB to help combat ad fraud. This data was crawled from the URLs on the app's developer pages. Not all apps have app-ads.txt, many do not. Additionally, below are only apps that have the ad network listed as DIRECT instead of RESELLER.
