This document summarizes a case study about how Google's Panda algorithm update affected the website Review Centre. It discusses how Review Centre saw a significant drop in traffic after Panda, the actions they took to improve their site quality by redesigning pages, removing duplicate content, and limiting ads, and how they saw no recovery from Panda penalties over several months despite their efforts. It also examines different theories about what triggers Panda penalties and resources for sites affected by Panda.
