APK is the best file format used in Android just like exe for Windows. Android app stores are also called as APK stores. When you need to download any Android app or game apart from Google Play Store people used to search that app or game name with APK as prefix or postfix. By doing that you will get direct link to the app or game you want.
Best site for APK Downloads
There are lots of verified and awesome websites to download apks. For example uptodown and Apkpure. Many people ended up clicking advertisements instead clicking the correct download button due that some find it difficult to download apks. Once you download and install any apk from a website you have to check for updates manually. If there is any update available you have to manually download and install. I have better idea to download apks easily.
My recommendation is to go with third party Android apk store or app store. There are best app stores like uptodown app store, apkpure app store, Aptoide, AC Market. If you wish to download modded apk and cracked apks then AC Market is the best choice. Because AC Market has separate category of modded apps and games.
Third party app stores can keep track of downloaded apk files and auto update them for you. So no need to manually download and install when there is update available. That is a one advantage of using a apk store instead of relying on a website.

AC Market is one of the best APK store you can download. Aptoide is also a huge and popular app store. But using AC Market you can easily download modded apks.
