How Does Google Search Work? Understanding Search Algorithms

Every single day, Google processes over 3.5 billion searches, which equates to 1.2 trillion searches annually worldwide. But, have you ever stopped to wonder how Google manages to deliver results in mere fractions of a second? Or, why it’s often remarkably accurate in predicting exactly what you’re searching for? The secret lies in the intricate, yet fascinating world of search algorithms. So, how does Google Search work?

Decoding the Google Algorithm

Google’s search engine operates on a powerful set of rules or algorithms. In the simplest terms, an algorithm is a process or set of rules followed in calculations or problem-solving operations. Google’s search algorithm, more specifically, is a complex system that finds, ranks, and returns relevant and useful search results. The search algorithm is primarily composed of multiple smaller sub-algorithms, all working together.

To illustrate the complexity of the algorithm, consider its evolution. In 1998, when Google was first launched, its algorithm was relatively simple, relying largely on keyword matching. As of 2021, Google’s algorithm considers over 200 factors when ranking a website, including the site’s relevance to the search query, the quality of its content, and the number of links to the site from other websites, among many others.

Breaking Down the Process

The entire process of fetching results can be broadly categorized into three primary functions: Crawling and indexing, algorithms and ranking systems, and search query processing.

1. Crawling and Indexing

The World Wide Web is a vast, dynamic universe of interconnected web pages. Google’s web crawlers, often referred to as ‘Googlebot,’ begin the search process by crawling billions of pages on the web, discovering new and updated content to report back to Google. This involves following links on these pages, similar to how you might browse the content of a book.

To organize the information discovered during crawling, Google uses a process called indexing. During indexing, Googlebot processes the words on a webpage and where those words are located. All this information is stored in the Google index, a vast database stored in multiple computers.

2. Algorithms and Ranking Systems

Google’s algorithms and ranking systems are employed to find the most relevant pages for any given query. The search engine evaluates hundreds of factors, including the keywords, the relevance of the page’s content, the quality of the page, and the geographic location of the searcher, among others.

One of the key features of Google’s algorithm is PageRank, a system that decides the importance of a webpage based on the number and quality of links directing to it. This forms a major chunk of Google’s algorithm.

But, as the search query gets processed, what is the role of artificial intelligence (AI) in this function? How do we ensure that the sanctity of AI is maintained in this process?

3. Search Query Processing

Processing a search query involves deciphering the user’s intent and matching it with relevant content from the Google Index. The algorithm considers several factors such as the user’s location, language, and previous search history to return personalized results.

Consider for instance, a search for ‘pancakes near me.’ Google’s algorithm not only needs to identify relevant pancake-serving establishments, but it also needs to factor in your current location to give you meaningful results.

A key breakthrough in search query processing was the introduction of the BERT algorithm update in 2019, which allowed Google to better understand the context of words in search queries, especially for longer, more conversational queries, or searches where prepositions like “for” and “to” matter a lot to the meaning.

Artificial Intelligence in Google Search

Artificial intelligence (AI) has transformed the way search engines operate, and Google is no exception. The integration of AI into Google’s search algorithms has improved its efficiency and accuracy immensely.

Google’s AI journey began in earnest with the introduction of RankBrain in 2015. RankBrain uses machine learning (ML) to understand and interpret complex, multi-word queries and the intent behind them. By considering historical search data and user interaction with previous search results, RankBrain is able to deliver more accurate and relevant results.

In 2019, Google introduced the BERT (Bidirectional Encoder Representations from Transformers) algorithm update, a breakthrough in natural language processing (NLP). BERT can understand the context of words in sentences and interpret nuances of human language, thereby improving Google’s understanding of search queries.

AI and ML are undeniably crucial to the continual evolution of Google’s search algorithm. But in integrating these advanced technologies, how do we ensure the sanctity of AI is maintained, and that these powerful tools are used responsibly and ethically?
