The Internet plays an important role in the modern world, and imagining a world without it is literally impossible nowadays. You can get solutions to all possible problems on the Internet; it helps you in your business and professional occupation; it keeps you in touch with your friends and family through social networking; it helps you with your shopping, banking, and entertaining; and it connects you to the world, bringing a huge amount of information to your computer screen. But have you ever wondered how everything works so easily on the Internet and how you always get what you look for on the Web? Many of you might even be using the various services provided by search engines for over a decade now without giving much thought to the math behind them. Well, if you are wondering about how search engines, such as Google, Yahoo!, and MSN, work in solving your queries and how they always provide the right information when asked for, you must read on to find out.

How a URL Helps

In order to make things easy for you to understand, let’s consider a hypothetical situation: Say there is a huge library with a large number of books. Now, when you visit this library for some specific information, the first thing you will need is the assistance of a librarian. The librarian will take you to the particular book you need, checking the content list before finally reaching the page that contains the information you need. Likewise, the Internet plays the role of a huge library consisting of a gigantic amount of information, and the search engine acts as a librarian who finds the right web site (book) for you and the online web page where you finally get your information. Now, just as each page in a book has a number that denotes the specific page, every web page on the Internet has a URL that helps to identify it among an ocean of online pages. But unlike the number printed on the page of a book, URLs play a mighty big role in the world of search engines. URLs are one of the fundamental elements that make things function smoothly on the Internet.

“URL” is a shortened form for “uniform resource locator.” A URL consists of a formatted string of text that denotes a web page. It is used by web browsers, search engines, and other software to locate and identify the web page among a billion other pages present on the Web. URLs are developed by search engine optimizers (SEOs) who work hard in URL optimization, making each URL search engine–friendly. In earlier times, numbers, symbols, and codes were used in developing URLs, but it became difficult for search engines to locate each URL. Now, with a better understanding of the mechanisms and inner workings of search engines, SEO-friendly URLs are developed using keywords that better define the web page and make more sense to search engines. Expert SEOs use the most specific keywords in URL formation so the web page becomes easily traceable by search engines. SEO-friendly URL formation has several benefits, the most important benefits being better rankings by search engines, greater visibility, and increased traffic.
