Before that, let us learn us learn in detail about crawling and indexing, along with understanding how a search engine works. This will help you understand the effort and expertise that are required for making a website discoverable and highly ranked in the search results.
What is Crawling?
Crawling is the discovery phase, where search engines, such as Google, send out bots, spiders, or crawlers. These are automated programs that are used to find new and updated content. Here are the steps involved in crawling:
- Crawlers or bots start with a list of known web addresses, where they follow the links on those web addresses to find new pages. This allows evaluation of links across the web.
- Along with following the links, the bots discover pages through XML sitemaps that are submitted by website owners via Google Search Console and through manual URL submissions.
- The crawling budget of search engines is limited, which makes it mandatory for complex websites to optimise their structure so that the important pages are crawled first.
- Crawling allows website owners to control the bots or crawlers by using a “robots.txt” file, which can help in specifying the parts of a website that should be visited and the ones that should not be visited.
What is Indexing?
Indexing is the second phase that takes place after crawling. In this phase, the search engine processes and stores information in a massive database known as an index. Here are the steps involved in indexing:
- Search engines, such as Google, render pages using technology that is similar to a web browser. This is done to see the pages in the same way as a user would see.
- After that, the indexer analyses video files, texts, and images, along with the meta title and meta description, to understand the topic in the pages.
- Since Google prioritises near-instant results for a better user experience, it uses an “inverted index”. This helps in ensuring that the search engine does not have to search the entire page for a keyword when a user types a query.
- If the pages are of low quality, contain duplicate content, or have a “no index” tag, they get excluded from indexing.

Know How Search Engine Work?
Here is how search engines, such as Google, work in terms of crawling, indexing, and ranking web pages:
- Discovery via automated crawlers or bots: Search engines deploy automated bots that start by searching for a list of known web addresses. After that, these bots analyse the links within these web addresses to find new or updated content. This step plays a vital role in terms of ensuring that the database system remains updated with the latest content in the rapidly evolving web world.
- Navigate through the hyperlinks: The bots or crawlers tend to move across the web mainly by following the hyperlinks and XML sitemaps found in known web addresses. As soon as the bot lands on the website, it scans for links to other pages. This approach allows the bots to find deeper-level content that has not been manually submitted by the website owner.
- Render for full visibility: Search engines render the pages by executing code, so that they can see exactly what users see. The significance of this step is based on the fact that it helps in analysing hidden content that appears only after a page loads fully. Thus, search engines can improve user experience by analysing the relevance of the content in a detailed manner.
- Content analysis: After fetching the data, the search engine parses the data to extract texts, headings, meta title, and meta description. This helps in performing an in-depth analysis of the page’s topic, relevance, and content quality. After analysing the content, the search engine categorises the information and identifies the intended audience.
- Storage in the index: If a page has quality content, it gets stored in the “index”, which is a massive database consisting of billions of web pages. The index is a kind of digital library catalogue. The main reason for your getting near-instant results is that when you enter a query, the search engine searches the pre-organised index instead of the live web.
- Ranking and retrieval: The search engine uses ranking algorithms to sort the indexed pages. The algorithms evaluate several key factors, such as the loading speed of the page, site authority, and keyword relevance. This is because the search engine’s primary goal is to provide high-quality and most helpful answers at the top of the search page results, which is crucial for improved user experience.
