Headless Chrome means that the Chrome rendering engine is used, but all the "Chrome Controls" (such as the menu, previous and next buttons, URL bar, etc) are all hidden. Basically, just the webpage content is shown, but none of the standard user controls.
While this can be common for bots, there are many reasons why general users would see this view as well.. it's not really a "silver bullet" of bot detection.
Hi @jennifer_dungan,
Interesting point in regards to the "bookmarks" on mobile phones - something I'll want to look into!
100% not a sliver bullet, it has to be paired with other behavioural metrics. In our organisation's context, we do not expect a normal user to access the site via headless chrome and from the behavioural data is pretty obvious it's not a human.
The above was some suggested indicators to look out for.
Cheers,
Vernon
