Search engines such as Google and Bing have become an integral part of our daily lives and help us search through vast swathes of information on the internet.
But how do search engines work? In this article, we will provide a comprehensive guide to how search engines work, including crawling and indexing, ranking algorithms, search engine results pages (SERPs), search engine optimization (SEO), and the future of search.
Search engines are used to search the internet and collect data about web pages. They use automated programs, also called crawlers or crawlers, to perform this work.
To understand how search engines work, it is important to know that they do not index web pages automatically. Crawlers can only find pages that are linked from other pages, this means that if your site lacks inbound links, search engines may never find it.
To ensure that search engines find and index your pages, you can submit a sitemap, a form of a list of all your pages.
IMPORTANT: Don't forget to publish your sitemap.
As you become familiar with crawling and indexing, you will understand the importance of optimizing your pages for search engines. This means, among other things, that you use keywords and phrases that match the user's searches and that you provide high-quality content that other sites want to link to.
Search engines have ranking algorithms that determine the relevance and authority of each page. These algorithms take into account a variety of factors including keywords, backlinks, and user behavior.
The specific factors used by each search engine's algorithm are well-kept secrets, but experts have identified some of the key signals that influence search results.
To begin with, it is important to understand that search engines use many different factors to determine how web pages rank. Below you will find some of the most important factors that affect your positioning in search results.
Here the focus is on On-page SEO, a topic that we will go over in more detail in chapter three of this guide. But in order for you to have an idea of what on-page SEO is, it can be briefly explained like this; Search engines look for pages that are most relevant to the user's search query. This means that the content of the page should contain the keywords and phrases that the user is searching for.

Authority can be built using various techniques. You will learn more about this in the chapter Off-page SEO. Search engines consider the authority of the site and the page in their ranking process. Search engines take into account, among other things, the number and quality of incoming links from other websites, as well as the overall reputation or visibility of your website and its content.
Did you know: Older domains have higher authority which has an impact on the entire website authority.
Search engines track different user behaviors, such as click-through rates, bounce rates, and time spent on a page. These signals can indicate the quality and relevance of a page. From this guide, you will gain an overall understanding of how you can track and interpret these signals, and thus understand what you need to improve in your SEO work. As you become more familiar with ranking algorithms, you will begin to understand how they interact to determine the ranking of a page.
For example, a page with high relevance but low authority can still rank well if it has strong user signals. Experts in SEO and search engines understand the complexity of ranking algorithms and the many factors that contribute to a page's ranking. It is also important to understand that ranking algorithms are constantly changing and evolving, so it is important to stay up-to-date on the latest trends and best practices.
