by Satish Singh
If you keep up with digital marketing or even just regularly look online for services or any other information, you’ve probably heard about Google algorithms. But have you ever wondered what they’re exactly and how they affect websites and eCommerce stores’ ranking?
What are Google Algorithms?
Google’s algorithms are a complex system that searches out web pages that contain keywords you use to search. In other terms, it used to retrieve data from its search index and instantly deliver the best possible results on a user searched query. The search engine- Google uses a combination of algorithms and numerous ranking factors to deliver websites ranked by relevance on its SERPs.
Below I have compiled a full list of Google algorithms launches & updates that have rolled out over the years.

Core update- June 2nd, 2019
Google actually pre-announced this June 2019 Core Update on Twitter, letting the SEO industry know that a broad core algorithm update would be rolling out over the next few days.
