Search engines like Google, Bing, and Yahoo release timely updates every now and then. These updates seek to improve the performance of the search engine, especially in the way it ranks websites. Search Engine Algorithm updates can, therefore, be said to be software updates meant to incorporate more helpful features onto it. Some of the reasons that make it necessary to develop an algorithm update include the emerging issues relating to the search company’s search policies such as the authenticity of the websites and content they list, security flaws in the existing algorithm, and so on. Some of the common Search engine algorithm updates include;
1. Google Panda
This search engine algorithm update called Google Panda has been designed for the assignment content quality scores to websites’ web pages. This algorithm updates also down-ranks websites that have low-quality content, or are spammy, or have unhelpful content (or what can be said as thin content). However, before the algorithm update was made, panda’s main activity was to do the content filtering. Some of the key parameters used by Google panda to rank or de-rank any website include; the presence of duplicate content, thin content, plagiarism, user-generated spam, poor user-experience, and keyword stuffing.
2. Google Penguin
This update is meant to unmask and downrank websites that have unnaturally imposed link profiles, that can be considered as a spam in the search results through the use of manipulative tactics. With this algorithm update, Google has been able to impose penalties in a faster manner for this SEO policy’s violators. The recovery time has also been reduced significantly. This algorithm update works in real time.
This is a Google algorithm update developed in 2012 and rolled out in 2014. Its core task is to ensure that sites with a reputation of copyright infringements do not improve their ranking on Google. It, therefore, down-ranks websites that violate Google’s copyright policies.
