You can emulate specific viewer behaviors by automatically generating a User-Agent (UA) string based on your Platform, OS, and Browser selections. The UA tells the target site “who” is visiting (e.g., a Chrome user on Windows), which can reveal conditional content, such as mobile redirects or region-locked threats.
For full control, use the Custom option in User Agent Parameters. This overrides defaults with your own string, ideal for testing legacy browsers, bots, or evasion scenarios.
In Advanced Scan, enter your URL (e.g., https://silentpush.com).
Set Region (e.g., North America, uses residential proxy for realism).
Under User Agent Parameters:
Select Platform (e.g., Desktop) or click Custom.
In User Agent, enter a string (e.g., for mobile testing) and click Scan.
UA Structure Basics
A good UA starts with Mozilla/5.0 (compatibility flag), followed by platform/OS details, then browser specifics. Keep it realistic to avoid detection; invalid syntax (e.g., mismatched versions) may trigger bot blocks or errors.
