What is the meaning of Google algorithms?

Google's algorithms are a complex system that retrieves data from its search index and provides the most accurate possible results for a query in real time. The search engine uses a combination of algorithms and several ranking parameters to offer webpages rated by relevancy on its search engine results pages (SERPs).

Google's algorithms are now only updated a few times in its early years. Each year, Google makes thousands of improvements.

Most of these changes are so minor that they go unreported. However, the search engine will occasionally release big algorithmic updates that have a large impact on the SERPs, such as:

• Page Layout Algorithm

• EMD (Exact Match Domain)
