Today, we talk about how Google Search Engine works in order to improve your SEO. Last week, we talked about how you can use Google Trends to improve your SEO.
Google Search Engine scours tons of web content and evaluate many factors to determine what content is relevant to your search query. It gets such information from web pages, user-submitted content such as Google My Business and Maps user submissions, book scanning, public databases on the Internet, and many other sources.
Google follows three steps to generate web page results.
Crawling means Googlebot (also known as a robot, bot, or spider computer program) visits new, updated, and dead web pages to be added to the Google index. It is an algorithmic process to determine which sites, how many pages on each site, and how often to crawl.
There are two crawler types namely mobile and desktop. Each simulates a user visiting your page with a device of that type. Only one crawler (mobile or desktop) crawls all the pages of your site known as the primary crawler. The primary crawler for all new websites is the mobile crawler. Besides, the other crawler (mobile or desktop) recrawls a few pages on your site known as the secondary crawler to see how well your site works with the other device type.
Google will not crawl pages that are blocked in robots.txt, and are not accessible by login or other authorization protection. Google less frequently crawls duplicate pages e.g. different URLs to reach the same page or mobile and desktop versions of the same page.
Indexing means Googlebot processes each page it crawls to understand its content which includes text, tags and attributes, images, videos, etc.
Similar pages like canonical and duplicate pages with different URLs are grouped together into a document. Google Search Engine chooses one of the URLs in the document as its canonical URL which Google crawls and indexes most often.
Google does not index pages with noindex. Pages blocked by robots.txt, login, or authorization protection might be indexed even if Google didn’t visit them.
When a user enters a search query on Google Search Engine, Google searches the index to match pages and return the most relevant results. Relevancy is determined by hundreds of factors i.e. algorithm based on user experience.
