Google is arguably the most powerful tool on the internet. It is also one of the most used. In fact, Google processes over 40,000 search queries every second. This means Google handles 3.5 billion searches per day and over 1 trillion per month. But how exactly does Google work? How can it determine the best search results for your query? In this article, we’ll explain how Google search engine works.
Crawling and Indexing
Before you even do a search query, Google needs to sort out information that may be useful to you. Web crawlers gather information and data from hundreds of billions of web pages, which they organize in the Search index. This process begins when websites provide web addresses to crawlers, which crawlers visit to use links and discover other pages. Computer programs are used to determine which sites to crawl, how frequently, and how many pages to use from each website.
Google provides a webmaster tool to site owners to give them choices about how Google crawls their website. This includes giving Google detailed instructions on how to crawl their sites, requesting a recrawl, or they can choose not to be crawled at all. Once information is gathered, Google keeps track of it in the Search index. The Google search index holds hundreds of billions of pages and has a size of over 100,000,000 gigabytes.
Now that you know how Google gathers the necessary information for each user’s possible query let’s talk about how it determines which pages to show your first. Google uses a unique algorithm to determine the best possible, and most relevant answer to each user query. These ranking systems help analyze what you’re looking for and what information to provide to you.
Because Google wants to provide the best results, this algorithm is always changing. In a nutshell, this is how Google answers your questions:
- Analyze your words which includes interpreting your spelling mistakes and understanding the intent of your query, for example “annual travel and tourism trade exhibition“.
- Matching your search to relevant web pages by analyzing how often and where those keywords appear on a particular page.
- They then rank useful pages that can answer your search from the most relevant to the least.
- Google also considers the context of your query by tailoring search results according to your location, previous search history, and search settings.
- With all of this in mind, Google aims to provide the best results by evaluating how all relevant information fit together and provides you with a diverse set of options.
How Google approaches user searches depends on a variety of things:
- User focus – Google understands the importance of giving users the most useful results possible. But this process involves a lot of work and is continuously changing. To provide the best service possible, Google conducts search experiments that with a focus on real-time user testing and evaluation. In fact, in 2016 alone, they ran over 150,000 tests that resulted in more than 1,600 search improvements.
- Empowering webmasters – Google also offers extensive tools to help websites manage their online search presence. This is a particularly low-cost marketing tool that many site owners use to increase page traffic. Google’s various tools help website owners succeed in having their content, apps, and sites found. Through Search Engine Optimization, they aim to ensure that sites rise to page rankings in legitimate ways.
- Maximizing information access – It’s no use denying that Google is a massive information platform. It has become the most significant public library in the world. One driving force for Google is to give everyone open access to information. This means Google’s agenda is neutral and only wants to provide accessible information to anyone. They are constantly innovating and evolving the way people search content on the internet.
