Google has confirmed that it has performed a data refresh on its Panda algorithm.
In a tweet from its official account on micro-blogging service, Twitter (@google), Google revealed that the data refresh would affect less than one per cent of all search queries worldwide.
The search engine giant also provided a link back to a post published on its Webmaster Central Blog in May 2011; entitled "More guidance on building high-quality sites," the post provides more information for those that are unfamiliar with the Panda algorithm. Carried out on June 25, the latest data refresh represents Google's second update to Panda in a month - with a data refresh also previously carried out on June 8.
Unlike an algorithm update, a data refresh doesn't change the signals or the algorithm itself, meaning that it is unlikely to impact those within Internet marketing; instead it simply refreshes all of the data within the existing algorithm, according to Search Engine Watch.
SEW has also reported that Google is surveying users on how pleased they are with the search results provided. Presented in a Google pop-up, the survey asks users can choose to rate their satisfaction from "very satisfied" to "very dissatisfied."
Although Google has previously used human quality rating systems in the past, this is the first time - according to SEW - that it has asked users, albeit randomly, to provide feedback on the quality of search results directly from an SERP (search engine results page).
