What Is a Search Engine by Search4find ?

Every day we search the Internet for countless pieces of information. Sometimes the results aren’t what we’re looking for, and sometimes just the opposite. But how does the Internet know what we want? The answer is search engines.

It should contain words like google, bing, yahoo, Search4Find, Zapmeta, etc. These are all search engines that select the best results for the search query we type. Let us understand in depth what is a search engine.

Search Engine Definition.

The results are usually in the form of a list, often called a SERP or search engine results page. These results or information can be links to websites or a combination of images and videos, research papers, newspaper articles, etc.

There are many search engines, with Google being the most popular. Thanks to web crawlers, all these search engines can search so fast. Let us know in detail what is a search engine.

How does a Search Engine work?

With thousands of informative web pages available on the Internet, how does a search engine display relevant ones? How do you list these pages on our screen? What are the criteria? Let’s see how search engines work.

Search engines follow three steps to execute a user’s search query:
1. Crawling
2. Indexing
3. Ranking



Searching for new websites on the Internet begins with crawling. All search engines use these bots, called web crawlers or spider bots, to follow links to new web pages that are on known ones.

They get information by tracking from one site to another. Once the information is collected, it is indexed. While the indexing is going on, the spider constantly searches for new pages. After a certain amount of time has passed or depending on the amount of data collected, the spider will stop crawling.


Once the data is crawled, it is submitted for indexing and stored in the search engine’s database which is known as the index.

The function of an index is to retrieve information about the query as quickly as possible. This process can be done quickly by taking any of these steps:

  • Remove the stop word.
  • List of links to other sites.
  • Shows information about images or media embedded in the page.

All websites must be indexed to appear in search results. Sometimes when entering a search query, index results are returned quickly because some website links are already saved with the keyword.


The last step is to rank the results in the SERPs. Search engines have their own criteria according to which search results are listed. These signs or norms are hidden from the public. The function of ranking is to determine the order of web links on the results page.

One of the most common questions is: Do all search engines return the same results? And the answer is, not necessary. Each search engine has its own algorithm, on the basis of which it searches the web.

These searches are also based on factors such as your location, other users’ preference for the same keyword, their previous searches, etc. Therefore, all search engines return different search results.
Do all search engines give the same results?

Not necessarily. Search engines use proprietary algorithms to index and correlate data, so each search engine has its own approach to what it’s trying to find. Results can be based on where you are, what else you searched for, and what results in other users searching for the same topic. Each search engine weights them differently and gives you different results.

How do search engines evaluate results?

A single search can generate billions of relevant web pages, so part of a search engine’s job is to rank those listings using ranking algorithms. And while these algorithms are designed to give you the best answers to your questions, they are biased on a few factors. Search engines want to show you the results you click on, and they use a variety of factors to rank the results based on who they think you’ll be interacting with. These include, among others:

Use of keywords. Your search results must match at least a few words in your search query. Search engines prefer pages where these keywords appear prominently, such as a B in the page title, or often throughout the page.

Page content. Search engines give priority to quality content considering the length, depth, and width of web pages.

Backlinks. to or mention of a website to another website may be taken as a vote for the right to that website. Backlink ranking developed by Google PageRank ranks pages based on how many other websites link to this website and how high those websites are.

information for the user. Search engines such as Google use your personal information, such as search history and location, to provide you with uniquely relevant results.
