Google^[3] Panda is a significant update to Google’s motor de busca^[1] algorithm^[2], introduced in 2012. The crux of this update, as per patent^[4] 8,682,892, is a ratio that Google Panda creates using a sítio Web^[5]’s inbound links and reference queries. This ratio generates a modification factor applied to the entire website or a specific section, impacting its ranking in search results. If a webpage fails to meet a certain threshold, its ranking is lowered. Panda’s updates were initially rolled out monthly, but as of March 2013, they have been continuous. Notably, Panda 4.2 had a slow rollout starting on July 18, 2015. Google Panda, along with other updates like Hummingbird and Penguin, aims to ensure high-quality content is rewarded in search engine rankings.

Definições de termos

1. ↑ motor de busca. Um motor de pesquisa é uma ferramenta vital que funciona como parte de um sistema de computação distribuído. É um sistema de software que responde às consultas dos utilizadores fornecendo uma lista de hiperligações, resumos e imagens. Utiliza um sistema de indexação complexo, que é continuamente atualizado por web crawlers que extraem dados de servidores Web. No entanto, alguns conteúdos permanecem inacessíveis a estes rastreadores. A velocidade e a eficiência de um motor de pesquisa dependem muito do seu sistema de indexação. Os utilizadores interagem com os motores de pesquisa através de um navegador Web ou de uma aplicação, introduzindo consultas e recebendo sugestões à medida que escrevem. Os resultados podem ser filtrados para tipos específicos e o sistema pode ser acedido em vários dispositivos. Esta ferramenta é importante porque permite aos utilizadores navegar na vasta Web, encontrar conteúdos relevantes e recuperar informações de forma eficiente.

2. ↑ algorithm. An algorithm is a well-defined sequence of instructions or rules that provides a solution to a specific problem or task. Originating from ancient civilizations, algorithms have evolved through centuries and are now integral to modern computing. They are designed using techniques such as divide-and-conquer and are evaluated for efficiency using measures like big O notation. Algorithms can be represented in various forms like pseudocode, flowcharts, or programming languages. They are executed by translating them into a language that computers can understand, with the speed of execution dependent on the instruction set used. Algorithms can be classified based on their implementation or design paradigm, and their efficiency can significantly impact processing time. Understanding and using algorithms effectively is crucial in fields like computer science and artificial intelligence.

Google Panda (Wikipédia)

Google's Google Panda is a major change to the company'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.

CNET reported a surge in the rankings of news websites e social networking sites, and a drop in rankings for sites containing large amounts of advertising. This change reportedly affected the rankings of almost 12 percent of all search results. Soon after the Panda rollout, many websites, including Google's webmaster forum, became filled with complaints of scrapers/copyright infringers getting better rankings than sites with original content. At one point, Google publicly asked for data points to help detect scrapers better. In 2016, Matt Cutts, Google's head of webspam at the time of the Panda update, commented that "with Panda, Google took a big enough revenue hit via some partners that Google actually needed to disclose Panda as a material impact on an earnings call. But I believe it was the right decision to launch Panda, both for the long-term trust of our users and for a better ecosystem for publishers."

Google's Panda received several updates after the original rollout in February 2011, and their effect went global in April 2011. To help affected publishers, Google provided an advisory on its blog, thus giving some direction for self-evaluation of a website's quality. Google has provided a list of 23 bullet points on its blog answering the question of "What counts as a high-quality site?" that is supposed to help webmasters "step into Google's mindset". It has been incorporated in Google's core algorithm since 2015.

The name "Panda" comes from Google engineer Navneet Panda, who developed the technology that made it possible for Google to create and implement the algorithm.
