how google search works

Google receives over 63,000 searches per second; it is 5.6 billion searches a day. And, it uses over 200 factors in its algorithm before delivering the best SERP results. That’s pretty much. 

As you might already know, Google’s automated programs are “in charge” to find the best relevant web pages and serve search results. How? How Google works?

PS: Because Google has 2.5 trillion searches per year, I focus on Google mostly. 

In this post, we’ll look closer to the three stages of Google search:

  • Crawling
  • Indexing
  • Serving search results – ranking

Let’s begin.


Google uses search engine software that’s known as “web crawlers.” Web crawlers, or spiders are looking for new or updated pages. The spiders then store these pages in their web index to use later. They find these new or updated pages in different ways, such as following links mentioned in the pages. Many other factors affect Google spiders’ fetching your web pages. For now, let’s keep this topic for the next article.


Simply, the indexing process is about Google understanding what the crawled pages are about. While preparing your content and practicing SEO, ask yourself questions like:

  • How do you distribute your brand keywords throughout the website and pages? 
  • Do your contents include the main keywords and synonyms?
  • Do your URLs contain keywords?
  • Do you use visual content? Etc. 

Moreover, there are free cool tools that let you know how Google spiders “see” your pages. 

“SEO META in 1 CLICK” is a Chrome extension that summarizes and displays all metadata like script tags, links, headers, and other relevant information to work on SEO efficiently. mostly focuses on pure HTML; the way search engines see when they visit a page. This website shows headers, content length, number of external and internal links, META information such as meta tag, title, and more. 

Using the tool mentioned above, you can see the structure of your website in the eyes of Google spiders and know if your site lacks something. 

Serving search results – ranking

Recently Google had a new update that I find so efficient. As you may have noticed, when you click a result on a featured snippet in a SERP result, on the page, you are automatically heading to the exact text, highlighted by yellow. Google takes users to the precise text on an HTML page with SCROLL to the text technique.

As you see, Google search quality engineers are continually improving search results to serve users the best. For this, you are also somehow in charge if you want people to reach your content; you need to consider over 200 factors that affect ranking to optimize your website perfectly. Just keep in mind that SEO is not a one-time practice; you need to work on search engine optimization regularly. 

Fetching spiders

So, Google’s software programs called spiders fetch web pages and store them in Google’s index of the web. This fetching process continues with finding other pages by following the pointed links. At the end of the fetching, if there is, Google stores billions of web pages to use and retrieve search results later. 

Here I put an article you’d want to check out which discusses the importance of internal linking practices for SEO

Matt Cutts, the former Google engineer, explained what happens when a user searches on Google. He says that when Internet users start searching on Google, they don’t search on Google, but Google’s index of the web. Then Google software starts searching the index, and finds millions of results that can show users. 

How Google is going to show you, the SERP depends on your website’s content and other 200+ ranking factors. In short, those factors are:

  • Content relevancy
  • Keyword and its synonyms: usage and density
  • Domain authority
  • Page load speed
  • PageRank, etc. 

That is just a beginning. Ranking higher on the SERP is hard yet possible. It requires a considerable time investment but gives fantastic results. 


This article shortly explained how Google Search works and serves the Internet users. In the next article, let’s discuss this topic in-depth and see the ranking factors in the Google algorithm in detail. We’ll learn how to practice SEO for the best results. Stay tuned!
