+## Types of request handling in AdGuard
+
+AdGuard handles requests according to filters, user rules and settings enabled by the user. As a result, a request can be blocked, modified, allowed or, when nothing is done to it, just processed.
+
+Detailed information on how each request of yours has been handled by AdGuard can be found in the *Filtering log* (AdGuard for Windows, AdGuard for Mac, AdGuard Browser Extension) or *Recent activity* (AdGuard for iOS, AdGuard for Android).
+
+Regarding AdGuard filters, you can also check [our filter policy](../filter-policy), which describes in detail what and why each of our filters blocks.
+
+### Examples of blocked requests
+
+AdGuard DNS filter blocks requests to ad domains, such as `ad.doubleclick.net`.
+
+AdGuard Tracking Protection filter blocks tracking requests, such as `youtube.com/youtubei/log_event?`.
+
+### Examples of allowed requests
+
+AdGuard Base filter allows non-ad requests, such as `www.google.com/complete/search?q=`.
+
+Filter unblocking search ads and self-promotion allows requests to search ad-related domains, such as `www.google.com/aclk?`.
+
+Requests to websites that are added by the user to *Allowlist* are allowed.
+
+### Examples of modified requests
+
+Tracking protection feature with protection level set to *High* enables AdGuard URL Tracking filter which modifies requests by removing tracking parameters from them:
