Question 1

Does a website in the browser history mean our client went there?

Accepted Answer

Not necessarily, and this is the crux (§4, Example 1). A page loads adverts, trackers, images and redirects from many other domains automatically, and prefetch and background sync add more, so the history and cache routinely contain URLs the user never chose. The browser records how each URL was reached, typed, clicked, redirected, prefetched, and that transition data, not the bare presence of the address, tells you what was a deliberate visit.

Question 2

Our client cleared their history. Is it gone?

Accepted Answer

Usually not entirely: deleted browsing records are often recoverable from unallocated space, database free pages and cache remnants (§5), and, importantly, if the browser was signed into a syncing account, the history was copied to the cloud and survives the local clearing (§8, Example 2). Clearing the device does not clear the account. The clearing itself, if done after a duty to preserve arose, may also be a point in its own right (§7).

Question 3

Can we tell who was actually using the browser?

Accepted Answer

Only with care: the browser records a profile's activity on a device, not certainly a person's (§6, Example 3). On a shared computer or one with several profiles, the history may belong to someone else, so attribution is tested through the profile, the login state, the session artefacts and the timing against known presence, and corroborated. A search or visit is laid at a particular person's door only when that evidence supports it, not on the assumption that the device is theirs.

Question 4

What about private or incognito browsing?

Accepted Answer

It leaves a sparser trace, but not always nothing: private modes avoid saving normal history, yet remnants can survive in memory, DNS cache and related system artefacts (§5), and the destinations and network may still hold records (§8). So private browsing limits the local record without guaranteeing invisibility, and its gaps are stated honestly rather than read, in either direction, as proof.

Question 5

Are searches stronger evidence than visits?

Accepted Answer

Generally yes: a typed search term is a deliberate, articulated act that shows what the user actively sought, and it is among the most probative browser artefacts (§3). A page visit may be deliberate or automatic; a d own load is a deliberate acquisition. The weight follows the deliberateness, so searches and downloads, read with their transition and context, carry more than a bare auto-loaded URL, and the analysis says so honestly.

Question 6

The other side is relying on a long list of sites. How do we respond?

Accepted Answer

Have the list examined artefact by artefact (§4, Example 1). Very often a long, alarming list dissolves under transition analysis into a few deliberate visits and a mass of automatic loads, redirects and pop-up domains generated by ordinary browsing. The reconstruction of what the user actually chose, versus what the pages loaded on their own, and the profile and timing behind it, frequently reduces an over-read list to something far narrower and fairer. cflab. u k · e-disc ove r y. u k ©2026 Computer Forensics Lab Ltd ·cflab.uk ·e-discovery.uk ·info@cflab.uk ·+44 (0)20 7164 6915 Page 15 of 17
