Per-platform breakdown (10 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.

Bing minor high confidence This change involves a minor capitalization correction ('Xbox' to 'XBOX') and a product link substitution in footer navigation (Surface Laptop Studio 2 replaced with Surface Laptop Ultra). While technically a link was swapped, this appears to be routine footer content maintenance unrelated to DSA Article 40(4) transparency data or qualified researcher program documentation.

Bing DE minor high confidence This change involves a minor capitalization fix ('Xbox' → 'XBOX') and a product link substitution in a footer menu (Surface Laptop Studio 2 replaced with Surface Laptop Ultra). While technically a link change, it represents routine product catalogue maintenance on a support page footer rather than changes to DSA Article 40(4) transparency data or research access mechanisms.

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.

Aliexpress noise high confidence No change to the catalogue. Everything that changed on this page was outside the researcher-data section - menus, banners, or promotional elements. The catalogue text itself is identical. The original classification from before this correction is preserved in this record.

Google Google Search Data Catalogue noise high confidence Only a boolean value 'false' and blank line were added with no corresponding removal of existing content. This appears to be invisible metadata or markup change with no impact on user-facing documentation or research accessibility.

Google Google Shopping Data Catalogue substantive high confidence The page underwent major restructuring with 50 lines removed and 14 added, including wholesale removal of a detailed multi-section navigation hierarchy (Help → Upload products → Product data specifications with 7 sub-items) and replacement with a simplified two-item Merchants Nav structure. This represents significant reorganization of the catalogue page layout and navigation architecture, well beyond cosmetic changes.

Google Youtube Data Catalogue 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 Search Data Catalogue DE noise high confidence Only a boolean value 'false' and blank line were added with no accompanying text, links, or substantive content. This appears to be a metadata or formatting artifact rather than a meaningful documentation change.

Google DE Google Shopping Data Catalogue DE substantive high confidence The page underwent a major restructuring with 46 lines removed and 10 added, involving wholesale replacement of navigation breadcrumbs (from 'Hilfe > Produkte hochladen > Product data specifications' to 'Merchants Nav > Produktdatenspezifizierung'), removal of a 7-item content list reduced to 1 item, and substitution of 10 specification links with 4 navigation topic links. This represents fundamental reorganization of page hierarchy and content presentation rather than isolated link updates.
