Per-platform breakdown (11 platforms analyzed)

Temu noise high confidence No real change. The page alternates between two versions of itself (for example, with and without a login prompt), and this capture matched a version seen in a recent check. The original classification from before this correction is preserved in this record.

Xnxx noise high confidence No real change. The page alternates between two versions of itself (for example, with and without a login prompt), and this capture matched a version seen in a recent check. The original classification from before this correction is preserved in this record.

Snapchat DE noise high confidence Two blank lines were removed from the page source. This is whitespace-only change with no impact on rendered content, visible text, links, or research-relevant information.

Xvideos noise high confidence No real change. The page alternates between two versions of itself (for example, with and without a login prompt), and this capture matched a version seen in a recent check. The original classification from before this correction is preserved in this record.

Pinterest noise high confidence No line-level text differences detected and zero lines added or removed. The auto-detected classification of 'noise' is confirmed by the absence of any substantive content, link, or formatting changes.

Google noise high confidence No real change. The page alternates between two versions of itself (for example, with and without a login prompt), and this capture matched a version seen in a recent check. The original classification from before this correction is preserved in this record.

Google Google Search Data Catalogue substantive high confidence One outgoing link was replaced: the Austrian Google products page (google.at) was swapped for the German products page (google.de). This is a real change to catalogue access endpoints, though both remain within Google's product ecosystem and may indicate regional mirror updates rather than substantive DSA transparency data changes.

Google Google Shopping Data Catalogue noise high confidence The diff shows only reordering of navigation elements (Search, Clear search, Close search, Main menu, Google apps) with no functional content change. The one link change (google.de replacing google.at in the products tab URL) is a minor regional parameter variant that does not affect the catalogue's substantive transparency data or access.

Google Youtube Data Catalogue noise high confidence Language navigation links were converted from plain text to hyperlinks with ?hl= locale parameters, and a cookie notice was added. These are UI/formatting changes and parameter variants of the same base URL—no new substantive content, datasets, or access endpoints were added or removed.

Google DE noise high confidence No real change. The page alternates between two versions of itself (for example, with and without a login prompt), and this capture matched a version seen in a recent check. The original classification from before this correction is preserved in this record.

Google DE Google Shopping Data Catalogue DE substantive high confidence A single outgoing link was replaced: the Austrian Google products page (google.at) was changed to the German Google products page (google.de), both with identical URL structure. This represents a genuine link change affecting the catalogue page's external reference, despite the minimal text diff which appears to be whitespace/formatting normalization around UI elements.
