Panda / BabyPanda

Panda is a site-wide demotion system for pages with thin or low-quality content — applying to the entire website, not just individual pages. When too large a share of a site is rated as 'thin content' (content-poor pages), all pages of the site rank worse. BabyPandaV2 is a newer, more finely calibrated variant of the same principle.

A demotion system calibrated to rater judgments — similar to chard it judges content quality, but based on site-wide patterns rather than individual pages.

Site-wide thin/low-quality demotion; BabyPandaV2 = a newer/lighter variant. Not a single-field score but a demotion system oriented to rater judgments. [B/O]

Trust is primary (a site with lots of thin content is seen as unreliable), Expertise is indirect (thin content signals a lack of subject-matter competence to raters).

For sites with thousands of automatically generated pages, Panda is a real risk. Pages showing only raw data without context or added value can drag down the site average. Active pruning (removing or improving weak pages) is more important than constantly adding new ones.
