Amit Singhal, Google"s head of search, published a post in Google Webmaster Central blog describing the ways to make the websites friendly with Panda algorithm change. Amit advised publishers to continue their focus on delivering the best possible user experience on their websites and not to focus too much on what they think are Google"s current ranking algorithms or signals.
The Google official claimed that the panda update has improved rankings for a large number of high-quality websites. He also said that the company is planning to roll out 500 more search improvements in 2011 as well.
"Panda was just one of roughly 500 search improvements we expect to roll out to search this year. In fact, since we launched Panda, we've rolled out over a dozen additional tweaks to our ranking algorithms, and some sites have incorrectly assumed that changes in their rankings were related to Panda. Search is a complicated and evolving art and science, so rather than focusing on specific algorithmic tweaks, we encourage you to focus on delivering the best possible experience for users," said Amit Singhal.
Amit also stated some questions, which Google ranking signals considers while searching for a query. Those questions include:
* Would you trust the information presented in this article?
* Is this article written by an expert or enthusiast who knows the topic well, or is it more shallow in nature?
* Does the site have duplicate, overlapping, or redundant articles on the same or similar topics with slightly different keyword variations?
* Would you be comfortable giving your credit card information to this site?
* Does this article have spelling, stylistic, or factual errors?

* Does the page provide substantial value when compared to other pages in search results?
* How much quality control is done on content?
* Does the article describe both sides of a story?
* Is the site a recognized authority on its topic?
* Is the content mass-produced by or outsourced to a large number of creators, or spread across a large network of sites, so that individual pages or sites don"t get as much attention or care?
* Was the article edited well, or does it appear sloppy or hastily produced?
* For a health related query, would you trust information from this site?
