How Does Search Engine Works?
Search engines perform several activities in order to deliver search results. A few such activities according to Google algorithm are listed below;
- Crawling– Process of fetching all the web pages linked to a website. This task is performed by the software, called a crawler or a spider (or Google bot, in case of Google).
- Indexing– Process of creating index for all the fetched web pages and keeping such pages into a giant database from where it can later be retrieved. Essentially, the process of indexing is identifying the words and expressions that best describe a page and assigning the page to related keywords.
- Processing– When a search request comes, the search engine processes it, i.e. it compares the search string in the search request with the indexed pages in the database.
- Calculating Relevancy– It is likely that more than one page contains the search string, so the search engine starts calculating the relevancy of each of the pages in its index to the search string.
- Retrieving Results– The last step in search engine activities is retrieving the best matched results. Basically, it is nothing more than simply displaying them in the browser.
Search engines such as Google and Yahoo! often update the relevancy of algorithm dozens of times per month. Sometimes we experience sudden change in your rankings, most of such changes are due to an algorithmic shift or something else outside of your control. Although the basic principle of operations of all search engines is the same, the minor differences between their relevancy algorithms lead to major changes in results relevancy. This is where we need the services of SEO companies who keep tab on such changes periodically.
