How Google Search works?
The life span of a Google question is less than half of a second, and involves quite a number of steps before you see the most relevant results. This is basically how it works:
In links are actually the hyperlinks you get from the owners of different websites. The links when clicked lead you to the actual page of the specific website. As an owner you would both want to connect to other websites, or request the link from them, or you may write or create such an attractive or essential or useful content in your web site, that other web sites are allured to link back to you.
All well and good. However, in truth, Google is not a fool proof search engine and delivers lots of unhealthy results, which leads us to believe that its search could be manipulated up to a certain extent. What we need to understand is that when you do a Google search, you aren’t actually searching the particular website in which the most relevant information is present, you’re searching Google’s index of the web, or at least as much of it as we can find.
Google gives significance to the words adjoining the main keyword and that is how it matches and loads up the desired content.
What makes Google so incredible as a search engine is that although plenty of complex processes are happening in the background, from a consumer perspective, it’s simple and straightforward to use. However, its shallowness is evident by the way it places results from some irrelevant websites at the prime of so many search outcomes.
Google does this with software programs called spiders. Spiders start by fetching a few web pages, then they follow the links on those pages and fetch the pages they point to and follow all the links on those pages and fetch the pages they link to and so on,until Google indexes a pretty big chunk of the web, many billions of pages stored across thousands of machines. Google database stores the most relevant results in it its database, ready to be fetched when you type in the keyword on your computer. And thus the magic begins!
How does Google know which documents I really want? How many times does this page contain your intended keyword? Does the website have any navigation errors? Is the content relevant and useful for the intended audience? Is this page from a high quality website or low quality? Has the content been updated regularly? How many inbound and outbound links are pointing to the website? What is this page’s PageRank? By asking more than 200 of these questions, founders Larry Page and Sergey Brin came up with a formula that rates a web page’s importance by looking at how many outside links point to it and how important those links are. Finally they combined all those factors together in an algorithm which produces each page’s overall score and sends you back your search results about half a second after you submit your search. Pagerank algorithm is the core of Google search results.
At Google, the commitment to delivering useful and impartial search results is taken very seriously. And they don’t ever accept payment to add a site to their index, update it more often or improve its ranking. In hindsight, though the system is not 100% accurate, it is still quite accurate and is changing the world as we see it.
