Per-platform breakdown (9 platforms analyzed)

Aliexpress 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.

Bing noise high confidence Only a Trace ID changed (session/tracking token), with no modifications to actual content, links, or DSA compliance document references. This is invisible metadata and does not represent a meaningful update.

Booking noise high confidence The page changes consist entirely of URL parameter updates (tracking/affiliate labels and session IDs) in navigation and footer links. No new DSA compliance documents (risk assessments, audit reports, or audit implementation reports) were added. The link targets remain functionally identical—only query parameters changed for analytics/tracking purposes.

Google Google Shopping Data Catalogue noise high confidence The diff shows 1 line added and 1 line removed with identical visible content in the Shipping field description. This appears to be a whitespace or invisible character change with no functional difference to the documentation.

Google Youtube Data Catalogue noise high confidence The change removes URL query parameters (?target=_blank and ?hl=xx language variants) from language selector links while preserving the underlying link targets and navigation structure. This is a parametric URL normalization with no impact on actual catalogue content or research access.

Google DE Youtube Data Catalogue DE noise high confidence No substantive changes detected: zero lines added or removed, no links modified, and hash change with identical functional content. This is a null or parameter-variant change typical of DSA Article 40(4) monitoring noise.

Shein 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 formatting with no impact on rendered content, links, or research-relevant information.

Temu minor high confidence A single line of text was replaced with another single line. The change from 'Search related words' to 'temu.local.goods.v3.add' appears to be a UI label or internal identifier update with no substantive impact on research data access or transparency disclosures.
