How Search Engines Work
Understanding how search engines operate is fundamental to learning the significance of search algorithms. In this chapter, we delve into search engine functionality, exploring the core components that power the search experience.
Overview of Search Engine Functionality
Core Components
At the heart of every search engine lies a sophisticated infrastructure comprising three core components: crawling, indexing, and ranking.
Crawling: Think of crawling as the exploration phase. Search engine bots, commonly known as crawlers or spiders, traverse the web, navigating from one page to another. During this process, they discover and collect information about web pages.
Indexing: Once information is collected, the search engine indexes the content. Indexing involves organising and storing the gathered data in a structured manner. This indexed database serves as the foundation for delivering search results.
Ranking: When a user enters a query, the search engine employs algorithms to rank the indexed pages based on relevance. The ranking process determines the order in which results appear on the search engine results pages (SERPs).
Table 1: Core Components of Search Engine Functionality
| Component | Description |
|---|---|
| Crawling | Exploration phase where search engine bots discover and collect information about web pages. |
| Indexing | Organization and storage of collected data in a structured manner for quick retrieval. |
| Ranking | Utilization of algorithms to determine the relevance and order of search results. |
Crawling and Indexing in Action
Let’s visualise this process with a scenario:
- Discovery (Crawling): Imagine a crawler as a diligent explorer traversing a vast library. It systematically moves through the aisles, picking up books (web pages) and noting down their titles and content.
- Organisation (Indexing): Now, envision the crawler returning to a central desk where the librarian (indexing system) categorises and arranges the collected books based on topics and themes. Each book is assigned a specific location for quick retrieval.
- User Query (Ranking): When a reader (user) asks the librarian (search engine) for books on a particular subject, the librarian refers to the organized index, retrieves relevant books, and presents them in a ranked order, ensuring the most pertinent ones are easily accessible.
The Evolution of Search Engines
The journey of search engines is a fascinating timeline that reflects the evolution of the digital landscape:
| Year | Milestone |
|---|---|
| 1990s | Emergence of the first search engines, including Archie, Gopher, and early web directories. |
| 1996 | Introduction of Google, along with the revolutionary PageRank algorithm. |
| Early 2000s | Rise of algorithm updates focusing on link quality, relevance, and user experience. |
| 2010s | Dominance of mobile search and the advent of machine learning algorithms like Google’s RankBrain. |
| Present | Ongoing advancements in natural language processing and the integration of AI in search algorithms. |
Major Algorithmic Updates
Over the years, search engines have undergone transformative updates to adapt to changing user behaviours and combat manipulation. Notable updates, such as Google’s PageRank algorithm and the introduction of user-centric algorithms, have shaped the landscape of online search.
| Year | Search Engine | Name | Description |
|---|---|---|---|
| 2018 | Medic Update | Focused on health-related websites, emphasizing expertise, authority, and trustworthiness in medical and health content. | |
| 2019 | BERT (Bidirectional Encoder Representations from Transformers) | Enhanced understanding of context and nuances in search queries for more accurate results. | |
| 2020 | Core Web Vitals | Emphasized user experience by incorporating page speed, interactivity, and visual stability as ranking factors. | |
| 2021 | Page Experience Update | Expanded Core Web Vitals’ impact on rankings, prioritizing sites offering a positive user experience. | |
| 2022 | MUM (Multitask Unified Model) | Focused on understanding complex queries and providing more diverse and comprehensive search results. |

Types of Search Algorithms
In this chapter, we will explore the various types of search algorithms that power the world of online searches. Understanding these algorithms is essential for crafting effective SEO strategies and optimising your digital presence.
Traditional Ranking Algorithms
Overview of Traditional Algorithms like PageRank
Traditional ranking algorithms have played a fundamental role in shaping how search engines evaluate and rank web pages. One of the pioneering algorithms in this category is PageRank, developed by Google’s founders, Larry Page and Sergey Brin. In the early days of web search, PageRank revolutionised the concept of authority and influence on the internet.
How PageRank Works: PageRank operates on the premise that the importance of a web page can be quantified by the number and quality of links pointing to it. Each page is assigned a numerical value, and this value represents its authority. The more high-quality links a page accumulates, the higher its PageRank.
Strengths and Limitations of Traditional Algorithms
