There are many components of a search engine that determines ranking and popularity. A search engine is a computer system that provides search results for users. The components of search engines help the user find what they are looking for among the billions of web pages on the internet.
The first search engines were created in 1990 by engineer Alan Emtage and his student, Ben Grosser. The first web-crawler or spider was called ‘Archie’ and it was designed to explore the World Wide Web. However, the term ‘search engine’ wasn’t coined until 1994 by an engineer at AltaVista company named Bill Slavin.
Today, Google is one of the most popular and widely used search engines on the internet with a market share of about 90% as of October 2018.

1. Web Crawler
The components are responsible for finding and analyzing sites on the internet to index them for search engine.
A web crawler is a software application that searches for and analyzes content on the internet. Once they have found the content, they store it in a database to be analyzed later.
Web Crawlers are designed with various tasks in mind, which is why there are different crawlers for finding different types of information.
Example:
– A web crawler with specific search engine optimization (SEO) skills would find keywords to increase the visibility of a site on search engines.
– A web crawler designed to find information about competitors would look for content about their industry or company within specified domains.
– A blog bot is used to manage blogs.
2. Indexer
A system responsible for parsing and storing web pages, metadata, and other files into the search engine’s cont
An indexer is an integral part of the content management process. It analyzes the content of a site, extracts useful information from it, and stores it in a database so that it can be parsed by search engines.
The indexing process involves identifying relevant words on a page – often through analyzing URLs or keywords – then extracting them to create an index entry. This allows search engines to find your content, for example for sites with many pages on the same topic.
Indexers are typically used by Internet service providers (ISPs) to help organize their websites’ directory structure – they use them to find new web pages that have been added to their site during updates
3. Crawling Program
A crawling program is a program that controls how pages are crawled by the web crawler. The crawling program tells which site to crawl and how fast to crawl it.
Web crawlers are needed in order to search the web for specific data sets. They are used in the SEO industry to improve the ranking of websites. Web crawlers allow you to crawl sites through links. And can also find content that is not linked by searching for keywords on pages.
A crawling program is a specially created algorithm that controls how pages are crawled by a web crawler. They are programmed by people who want to target specific data sets or who want to exclude certain data sets from being crawled. These programs can be used in two ways:
1) To control how pages are crawled by a web crawler,
2) To exclude certain data sets from being crawled
4. Ranker
Ranker is a system that ranks web pages based on their quality and relevance to user queries or based on their popularity.
The ranker system may comprise of, but not limited to, links, links to other pages ranking higher than the page in question, links to pages that are ranked lower than the page in question.
The rankings may be compiled based on user preferences. And the ranker system may be updated with changes in user preferences over time.
The ranker system can also use information about how many times a page has been visited by one or more users over time as an indication of the relative importance of a webpage.
In web design and development, a “ranker” is typically a search engine field form for determining the Google PageRank for any given URL.
5. Database Management System (DBMS)
A database management system (DBMS) is a collection of programs that manage the storage and retrieval of data, usually using a table-based relational model.
The DBMS performs the following functions:
1. Records data about web pages on a search engine.
2. Stores this information in tables and assigns each table a unique ID number that can be used to identify it.
3. Allows queries to be performed with the same syntax as those done on an ordinary spreadsheet such as Excel, such as “show me all webpages with ‘cat’ in them” or “show me all webpage IDs where the length is greater than 7”.
6. Search Engine User Interface (SEUI)
SEUI is an interface that allows users to communicate with the search engine through keyword queries or autocomplete.
SEUI can be implemented in a number of ways, from a pop-up box at the top of a website to a separate tab in the browser to a search bar at the top of a page. The SEUI should be designed in such a way that it’s intuitive and easy for the user to interact with.
The design of SEUI is one of the most important things when it comes to optimizing your digital marketing campaigns. It needs to be optimized so that your target audience can easily find what they are looking for and convert them into customers.
Companies should invest time and money in designing their SEUI for optimal conversion rates rather than trying out different designs.
Conclusion
The components of a search engine are the backbone of the internet. And it has a vital role in determining ranking and popularity.
A search engine’s worth is based on its ability to deliver relevant information as quickly as possible, given a set of keywords or a phrase.
An SEO company can help improve the rank of your website on major search engines. It may also help you achieve more traffic from social media platforms.
Search engines are used to locate information on the internet. The components of a search engine are the input, algorithms, output, and web crawlers.
Search engines allow people to search for information in a quick and effective manner. They also provide the user with the ability to find specific information when they need it.
