What is a search engine?

The so-called search engine is a system that uses programs to collect information on the Internet, reorganize and process it, and provide customer retrieval services. Therefore, the main function of search engines is to crawl and build indexes to provide users with search results.

The key to the operation of the Google search engine: crawler and index

Through the structure of web links, search engines tie together all the pages on a website. Facing hundreds of millions of documents, web pages, files, videos and various media, Google's search engine crawls information through crawling, parses the code in these pages, and uses them as code fragments that can be marked , build an index (index), store it in the database, and then extract it for use when the user searches.

Five steps to dismantling how Google's search engine works

Analyze keywords > Compare search queries > Rank useful pages > Consider background information > Return the most useful search results. 

1. Analyze keywords

The core method of returning useful information is to " understand the meaning of each search  ".
In order to provide users with more relevant query results, search engines first analyze the meaning of search terms. The language model system established by Google can analyze each string of search terms and find the most "key" terms, and then conduct in-depth searches. For example, "Where can I buy a helmet?", the second key in this sentence is the action of "buy". The search results (SERP) will show results such as shopping websites, store locations, etc., rather than knowing about helmets knowledge of the material or properties of the site.

2. Comparison search query

When users search for terms, algorithms search for your keywords and analyze where and how often those keywords appear on your website.
In addition to comparing keywords, Google will also try to provide more useful relevant information. For example, when you search for a broad keyword such as "cat", the results will not only show all pages with the word cat, but also appear with the word cat. List of cat breeds, photos, videos and other information for you.

3. Rank useful pages

There may be tens of millions of pieces of information for each keyword, so Google will use an algorithm to "assess the usability of the website" and prioritize the best search results.
These algorithms analyze the usefulness of a website to users, taking into account hundreds of different factors, as well as users' search preferences, as a criterion for a website's credibility and authority.
Any information that is harmful or violates the user will be considered spam by Google and will be removed from the site's search results page for violating the Webmaster Guidelines .

4. Consider Background Information

Based on your past searches and your location, Google will tailor the search results that best suit you.
For example, it provides geographically relevant information based on your location, region and country. For example. Searching for bubble tea in Taiwan will bring up information about nearby beverage stores; searching for bubble tea in Korea will give priority to articles and stories about bubble tea.
Search history is a "personalized" search result. For example, if you want to search for puppies, and you have recently searched for "puppy food selection", then you will think that you are looking for "feed" and not other "puppies" related information.
In addition, if you use the " Safe Search " tool or set your "Preference Language", Google will use these " Search Settings " as an important basis for judging search results.

5. Return the most useful search results

Based on your search, Google evaluates how to "multiple representations" of search results that are most appropriate and relevant. For example, are the search results pages related to multiple topics, or are they related to a single topic? Are there too many similar pages?
In addition, Google continues to improve the ranking system, in order to provide users with more high-quality information. Therefore, the content screening and assessment conditions are becoming more and more stringent.
