You might have heard of the term “Algorithm” before, it is a process or set of rules used in calculations and problem-solving operations.
Today, we will get an overview of different Google Algorithms that have transformed the search experience for us.
Google’s mission statement is to organize the world’s information and make it universally accessible and useful.
To achieve its mission, Google implements changes in its formula or the algorithm. Many changes are pushed by Google in a year, some are small improvements in their current algorithms and some just turns the industry upside down.
So let’s take a look at all the important algorithms –
1. Google Panda
Google Panda was released by Google on February 24, 2011, and is used to detect duplicate, plagiarized content and excessive use of keywords.
The main purpose of the algorithm is to reward high-quality websites and diminish the presence of low-quality websites on Google’s search engine results.
Google Panda impacts your web page rankings by assigning a “Quality Score” to the page.
Although the algorithm rolled out years ago it is still active and will affect your website if it detects any sort of plagiarised content.

2. Google Penguin
Google rolled out Google Penguin on April 24, 2012, and is used to detect irrelevant links, spammy links, black hat link building techniques in your web pages.

The only way to be safe from getting penalized is to remove the links from your web pages that are not relevant.
