What are Penguin and Panda? Why are so popular in Google search?

Pleas explain the reason why these names are popular in the internet?

As Danny Sullivan put it, if you consider the Google algorithm as an engine, Panda and Penguin are algorithm changes that were like putting a new part in the engine such as a filter or a fuel pump. But, Hummingbird wasn't just a new part; it was a completely new engine.

Penguin is related to quality of links while Panda is for content.

What sets Google apart is how it ranks search results, which in turn determines the order Google displays results on its search engine results page (SERP). Google uses a trademarked algorithm called PageRank, which assigns each Web page a relevancy score.
Penguin and Panda are Google algorithm.

Yes, I completely agree with you.

Google Panda is a change to Google's search results ranking algorithm that was first released in February 2011. The change aimed to lower the rank of "low-quality sites" or "thin sites", in particular "content farms", and return higher-quality sites near the top of the search results.

Google launched the Penguin Update in April 2012 to better catch sites deemed to be spamming its search results, in particular those doing so by buying links or obtaining them through link networks designed primarily to boost Google rankings.

The panda algorithm, named after a standout amongst its engineers, Navneet Panda, landed on the scene in early 2011. Its primary algorithmic objective is to decrease the number from claiming low-quality locales showing up during alternately close to the highest priority on Google’s comes about. Toward In huge numbers SEOs thought this might have been meant specifically at “content farms” – destinations that exist exclusively to raise validity once amassed for different sites’ prominent substance. Eventually, it got to be reasonable that panda need a much that's only the tip of the iceberg comprehensive clue for the thing that it implies on make An prominent webpage.

The Panda update is a filter that is designed to penalize “thin” or poor content from ranking well. Whereas Penguin is a filter that is designed to penalize websites that have bad link building techniques and keyword stuffing.

Penguin and Panda are algorithm updates that were introduced by Google to improve the quality of search results. These updates were designed to combat spammy and low-quality content and to ensure that high-quality, relevant content appears at the top of search results.

Penguin was first released in 2012, and it focuses on penalizing websites that engage in link schemes or have a high number of low-quality links pointing to their site. This update targeted manipulative techniques that webmasters were using to artificially boost their search engine rankings.

Panda was first released in 2011, and it aims to identify and penalize websites with low-quality content or thin content. This update targeted websites that had a high percentage of duplicate, irrelevant, or low-quality content, and it helped to boost the rankings of websites with high-quality, original content.

Penguin and Panda have become popular in Google searches because they have had a significant impact on search engine rankings. Websites that were previously using manipulative techniques to boost their rankings have seen their rankings drop significantly, while websites with high-quality content have seen their rankings rise. As a result, webmasters and SEO professionals have had to adjust their strategies and focus on creating high-quality, relevant content in order to rank well in Google searches.

Thus, the basic difference between Google Panda and Google Penguin is that Panda targets sites that are spam, and Penguin deals with bad linking and overstuffing of keywords.
