How does Google find Web Pages?
How does Google find Web Pages on the Internet? Google is the number one search engine on the internet today. Have you ever wondered how Google finds webpages on the Internet?
Where does the information that is displayed by Google when you search for a particular term come from? You will find out in a matter of seconds.
Well, we are going to focus on how Google generates results from webpages. Meanwhile, let’s begin by mentioning some of the sources of Google’s information as follows:
- Public databases on the Internet
- Book scanning
- User-submitted content
Today we will dive deep into the basic steps Google takes to generate results from web pages.
How Does Google work to find Web Pages
Let’s take a quick glance at the three primary functions of Google and how it works to find webpages.
- Crawl: Search the Internet for content using spiders and robots
- Index: Organize and store webpages ready to be displayed as results when queries by users.
- Rank: Display the best answer to the user’s query when by the most relevant to the least relevant.
Crawling to find Web Pages
First, Google sends robots that are also known as crawlers or spiders to find both new and updated content. This content can be in form of an image, a web page, a video, or even a pdf document. The bottom line is the is content is discovered by link regardless of the format. This process is called Crawling.
The newly discovered content is added to their index which is known as Caffeine- a large database of discovered URLs.
Equally important, Google must from time to time look for new web pages and add them to its existing database of webpages. This is because it is not the central registry of all webpages.
In fact, Google already knows some pages exist because it has visited those pages before. In addition, it discovers some new pages when it follows a link from a known page to a new page.
Google also discovers other pages when the owner of the submits their sitemap for Google to crawl.
For some managed web hosts, for instance, Wix and Blogger, Google might be informed to crawl or any updated or new content in your site.
Secondly, once the crawling process takes place and Google discovers a page, it tries to understand what the content on the page is all about including the visuals such as images and videos.
Google processes and stores the information in Google Index, which massive database of all the content that is discovered and considered good enough for Google searchers.
This process is referred to as indexing.
Remember Google is a business like any other business and the Customer Experience is key.
Finally, when a user conducts a search, Google scours the Index for the most relevant answer. It determines the high-quality results to the query however, some factors such as location, language, device(laptop or desktop) are also factored in here.
The search results are ordered from the most relevant to the least relevant with the aim of solving the searcher’s problem or query. The ordering of search results by relevance is called Ranking.
As a matter of fact, we will believe the higher a site is ranked, the more relevant Google deems that the information is relevant to the searcher’s query.
In conclusion, it is worth noting that a site owner can instruct Google crawlers not to crawl certain pages or categories of their website. Similarly, the site owner may instruct Google not to store certain pages in their index depending on many reasons.
Otherwise, if you want your webpages to be discovered by Google users, it is key to make sure they are accessible by crawlers and they can be indexed.
