How Does Google Find its Results?

No matter how we look at it, Google is a part of our everyday lives. But before Google became a household name and created their infinite number of ways to be incorporated in our society, it was simply a search engine. Google offered this crucial tool to conveniently accommodate our appetite for information on the World Wide Web. The search engine Gorilla quickly provides millions of results in a split second for any search query that a user searches for, any time, from anywhere in the world. This incredible convenience is certainly a luxury that our society might be in a different place without. Think about it, the overused term ‘Google it’ would have never existed.  But how does this happen?

Before Google can provide the infinite number of results in the search engine results pages (SERPs), these results need to be found. This is where the work of robots commonly called ‘spiders’ comes in to play. When these spiders get to work, they are busy generating lists of words from an inestimable number of pages across the internet. Their journey begins by looking at prevalent pages and widely used servers. These spiders will index the words on each page and try to follow every link found on any of the pages.

In order for the search engine to run as efficiently as possible, Google’s system runs on its own Domain Name Server (DNS) so it doesn’t have to rely on a separate Internet Service Provider (ISP). Google spiders look at the HTML version of any page taking two things highly into consideration; the words on the page, and where they can be found. With the exception of articles such as “a”, “an” and “the”, each word is crawled in a number of positions where they can be found on a webpage, including the title, subtitles, title tags, headers and footers. This is where Search Engine Optimization (SEO) becomes an integral part of your website being found online. Taking special consideration of these particular positions, Google’s spiders also pay close attention to the top 100 words that are used most frequently with greater emphasis in the first blocks of content on your homepage.

Google has nearly perfected their search engine tool for the masses and yet continues to constantly improve upon their algorithm to provide the most accurate and up-to-date results. The ever-changing landscape of SEO is what keeps us up-to-date on the latest information and the time-honored best practices that have exceptional results.
