Google doesn’t find every page on the web. Search engines start at some popular spots and repeatedly follow links from there, “crawling” their way across the web. A new website that nobody links to will not be found on Google unless its admins explicitly submit it and ask for it to be crawled.
How do search engines work- How search engine finds your website
Google gets to know about any new website through these 4 sources;
Domain Discovery:
Google DNS: Almost every time you visit a website, it needs to get the IP address for the website. Google DNS is very popular DNS around the world, DNS logs are very useful for discovering domains.
Domain Registrars:
Bigrock, hostinger, inmotion and other domain registrars
Web Page Discovery :
Google Toolbar / Google Omnibox / Mozilla Suggestions / IE Suggestions:
Google/Bing make very heavy use of toolbar/omnibox data. Whenever a user visits the page, the browser/toolbar logs the request.
Browser/Toolbar logs are a very rich source of signals for URL discovery and ranking. Assuming a page is visited by at least one person, the creator, Google can discover it from the logs.
Partners:
Sitemap.xml/ RSS feed: Website owners can communicate the structure and orphan pages of the website to search engine using sitemap.xml.

How do Search Engines Work: A Simplified Explanation
Search engines like Google, Bing, and DuckDuckGo consist of incredibly complex systems, but we can break down the basic concept into three main stages.
1. Crawling
- Web crawlers (also known as spiders or bots) scour the internet, following links from one page to another.
- They discover new pages and update information about existing ones.
- This process is ongoing, constantly updating the search engine’s knowledge of the web.
2. Indexing
- The information gathered by the crawlers is processed and stored in a massive database called an index.
- This index contains information about the content of each page, including keywords, images, and links.
- It’s like a giant library catalog, helping the search engine find relevant information quickly.
3. Ranking
- When you enter a search query, the search engine’s algorithm analyzes your request and retrieves relevant pages from the index.
- The algorithm ranks these pages based on various factors, including:
- Relevance: How closely does the page’s content match your search query?
- Authority: How reputable is the website?
- User experience: How easy is the page to navigate and understand?
- Freshness: How recent is the content?
- The search engine then presents you with a list of results, ordered by relevance.
Additional Factors:
- Search engine optimization (SEO): Website owners can optimize their pages to improve their ranking in search results.
- User behavior: Search engines track how users interact with search results to refine their algorithms.
- Personalization: Search results can be tailored to individual users based on their search history and location.
How Generative AI is Changing Search Engines
Generative AI is fundamentally altering the way search engines operate and interact with users. Here’s a breakdown of key effects:
1. Shift from Keyword-Based to Semantic Search:
- Understanding intent: Instead of merely matching keywords, search engines are now focusing on understanding the underlying meaning of a query.
- Contextual relevance: Generative AI helps search engines deliver more relevant results by considering the context of the search, including user history, location, and other factors.
2. Direct Answers and Summaries:
- Concise information: Search engines are increasingly providing direct answers to queries, rather than just listing links.
- Summarized content: AI can generate summaries of complex topics, making information easier to digest.
3. Personalized Search Experiences:
- Tailored results: Generative AI enables search engines to offer highly personalized results based on individual preferences and behavior.
- Predictive search: By anticipating user needs, search engines can provide suggestions and recommendations before a query is even completed.
4. Enhanced User Experience:
- Conversational search: AI-powered voice assistants and chatbots are transforming search into a more natural and interactive experience.
- Visual search: Image and video search capabilities are becoming more sophisticated, allowing users to find information based on visual cues.
5. Challenges and Opportunities:
- Information quality: Ensuring the accuracy and reliability of AI-generated content is a significant challenge.
- Content creation: The rise of AI-generated content could impact the way websites and content creators optimize for search engines.
- Ethical considerations: Issues such as bias, privacy, and copyright need to be addressed as AI becomes more integrated into search.
