Before jumping ring into understanding the algorithmic records let's first understand what are Google Algorithms. They are a logical system primarily designed to fetch data from its search index data directory and deliver in real-time the most relevant possible results for a searcher's query. Google's search engine integrates algorithms and various ranking factors to display web pages ranked by relevance on its search engine results pages popularly known as SERP's.
Google's algorithms are a composite scheme used to recover data of its search index plus immediately pass the most reliable outcomes for a query. The search engine practices algorithms and diverse ranking factors to display web pages ranked by relevance on its search engine results pages (SERPs).
In its initial years, Google only made a few updates to its algorithms. Now, Google advances thousands of developments each year. Most of the updates are so fine that they go unnoticed. Nevertheless, at times, the search engine rolls out significant algorithmic updates that significantly influence the SERPs, such as:
RankBrain
Panda
Penguin
Hummingbird
Pigeon
Payday
EMD (Exact Match Domain)
Page Layout Algorithm
