       Google Algorithms

Google’s algorithms are a complex system designed to recover data from its search index and quickly deliver the best possible results for a given query. The search engine utilizes a combination of algorithms and various ranking factors to present webpages ranked by their relevance on its search engine results pages (SERPs).

How does the search work?

The search process has three processes:

    • Crawling: The Google algorithm directs web crawlers to discover URLs on the internet and analyze their content. A web crawler is a program that systematically browses the web to index content automatically.

    • Indexing: The content found at these URLs is tagged with attributes and metadata that assist the search engine in categorizing the information.

    • Searching and Ranking: When a user enters a query, the search engine ranks the indexed content and returns results based on relevance to the query.

Ranking Algorithms

    This algorithm stands behind ranking pages on SERPs. There is a considerable number of unknown factors considered by the algorithm, including:

  • Content
  • Core Web Vitals
  • HTTPS
  • Site speed
  • Links
  • Anchor texts
  • Geographical locations (for local searches)
  • Mobile-friend lines
