Google Panda is a series of on-going algorithm updates and data refreshes for the Google search engine that the company rolls out to help refine its search algorithm to improve the value of search query results for users.Panda is updated from time-to-time. When this happens, sites previously hit may escape, if they’ve made the right changes. Panda may also catch sites that escaped before. A refresh also means “false positives” might get released.
