Search engines are online tools designed to assist individuals in locating information on the internet. A prominent example of a search engine is Google, which commands a dominant position in the worldwide search engine market share. When discussing search engines in this guide, the primary focus is on Google, given its widespread usage. Other search engines operate on similar principles, and optimizing your website for Google essentially prepares it for others as well.
How Search Engines Function
Search engines operate through several key steps:
1. Crawling
Crawling is the initial step in which search engines continuously scan internet webpages. They employ small programs, known as crawlers or bots, to follow hyperlinks and discover new pages, along with any updates to previously discovered pages. Google’s Martin Splitt describes this process as a systematic progression through the internet, page by page.
2. Indexing
After crawling, search engines index the information. They analyze and categorize the pages, storing them in an index. This index serves as a vast library containing information from all crawled websites, allowing it to be used as search results.
3. Picking the results
When a user submits a search query, the search engine retrieves the most relevant results from its index. The list of results is presented as a Search Engine Results Page (SERP).
4. Ranking
The order in which search results appear is determined by a variety of factors. These factors encompass elements such as the frequency of keywords, page loading speed, and the presence of hyperlinks. The ultimate objective of search engines is to furnish users with the most pertinent results.
While many search engines offer recommendations on enhancing your page’s ranking, the specific algorithms employed are closely guarded and subject to frequent changes to prevent exploitation. Nevertheless, adhering to best practices in search engine optimization (SEO) can guarantee the following:
- Search engines can effortlessly navigate your website, and you can even prompt them to index new content.
- Your content is appropriately cataloged with the correct keywords, ensuring its visibility in relevant search queries.
- Your content has the potential to secure a high position on the Search Engine Results Page (SERP).

Google’s Algorithm
Google’s Search Algorithm encompasses all the individual algorithms, machine learning systems, and technologies used to rank websites. These algorithms consider various factors, including the user’s query, the relevance of web pages, the quality of content, the usability of pages, and the user’s context and settings. The Google algorithm undergoes regular updates and adjustments, including minor daily updates and periodic core algorithm updates.
Search Quality Raters
In addition to algorithms, Google employs human data input from Search Quality Raters. These external Google employees follow specific guidelines, evaluate search results, and rate the quality of ranked pages. This evaluation is especially critical for pages related to important topics that can impact users’ well-being. While Quality Raters don’t directly influence rankings, their data is used to enhance the search algorithm.
Ranking Factors
Search engines keep the exact calculations of their algorithms secret, but many ranking factors are well-known in the field of SEO. Some of these factors are officially confirmed by Google, while others remain the subject of speculation. It’s important to focus on factors that have a proven impact and maintain a strong overall performance. Key ranking factors include:
– Well-targeted content
– A crawlable website
– Quality and quantity of links
– Content aligned with user intent
– Unique content
– EAT (Expertise, Authority, Trust)
– Fresh content
– Click-through rate
– Website speed
– Mobile compatibility
Additionally, factors like content depth, image optimization, topical authority, a well-structured page, social sharing, and the use of HTTPS may also positively affect your website’s rankings. Notably, the quality of content is considered the most crucial SEO factor. For more information on optimizing content for SEO, refer to the fourth chapter of this guide.
