How does google search work?
Google is the most utilized search engine across the world, 78% of all internet searches take place on Google. All businesses will find it in their advantage to understand how their websites rankings in search engine results are determined.
To keep it super simple, there are three major processes in providing the best search results.
Crawling -Indexing -Serving
Google uses many computers in order to crawl the billions of pages on the web. They run a program called Googlebot which uses an algorithmic process to determine which sites to crawl, how often, and how many pages to fetch from each site. As the Googlebot visits each of these websites it detects links on each page and adds them to its list of pages to crawl.
During indexing, the Googlebot processes each of the pages it crawls, and adds them into a massive index of all the words it sees and their location on each page.
Every single time a search is executed, Google’s computers search the index for matching pages and return the results that should be the most relevant.
Search result relevancy is determined by over 200 factors, like PageRank which is the measure of the importance of a page based on the incoming links from other pages. In other words, each link to a page on your site from another site adds to your site’s PageRank.
For websites to rank well in search results pages, it’s important to make sure that Google can crawl and index your site correctly. Google offers webmaster guidelines to help make sure that you have set your site up correctly to be crawled and indexed.
