We should know that Search engines are the primary source of traffic to your website/blog,Understanding how search engine works make us to understand SEO easier,Out of all the search engines presently Google is the best and the most popular search engine besides Bing, AOL and many more search engines.

Major functionality of Search Engines:

    Crawling and Indexing.
    Algorithms to calculate and get best results.
    Fighting Spam.


Crawling and building an Index

Why to crawl, the main reason for this is to know existence of something i.e. blog/webpage/article/image, so search engines find these information by crawling which is done by Google crawlers or spiders. These spiders fetch all the content available on Web Pages/blogs and also follow all the links present on it. They keep following every link present on the web and there by fetches everything. This is the most wonderful thing about crawlers; they go after everything on web. But this might be harmful when you want to preserve data or privatize pages on web, this can be done using Robot.Text file, no index attribute, using this you can also sometimes restrict the spider to enter into some page or private zone informing the spiders not to index some page or category. Crawlers fetch the data, and they have to store this data, some search engines short the data, and store them as an index which will be around giga bytes. This is called as “indexing”.


Algorithms for better search results

           Search engines are nothing but answering machines; they need to answer all the queries of the user by accepting keywords as their queries. There is a need to place best relevant results for search queries on top pages, in order of relevancy, For this all the search engines have specific algorithms consisting of many formulas and programs which have the ability to decide and display the most appropriate result possible. Whenever you type something in the search box, the algorithms start functioning in a way to find various clues to understand what you actually mean.
  1.           Spell Correction
  2.    Auto Complete
  3.    Synonyms Finder
  4.    Google Instant
  5.    Query Understanding
  6.    Search Methods
  7.     Author rank 


These are the various algorithms which will enable the search engines understand the query, and based on these clues it pulls out relevant content from the index.
        Finding the appropriate content is one step but ranking those is the next step. Ranking of these results is done by taking more than 200 factors into consideration. Few of those factors are site and page quality, freshness, uniqueness, keyword density, local, age, author rank etc.All this happens in just 1/8th of a second and the results are displayed in various forms like video, images, knowledge graph, snippets, news etc.

Fight SPAM
    
    Now besides their are advantages and disadvantages for everything, same way goes with search engine, so it’s the need of search engines to avoid the negatives i.e. SPAM,
    Search engines Fight SPAM as There are many people manipulating Google algorithms and trying to rank on the first page to drive more traffic to their website even if it doesn't satisfy all the Google ranking factors. This is nothing but spamming. Many new types of spamming techniques are constantly evolving everyday and Google Anti-spam community fight continuously to prevent spam and thereby keeping results relevant and genuine.The majority of spam is removed by various algorithms, like Google Panda, Penguin etc. which automatically remove spam content. Also manual action is taken sometimes where special attention is given to remove the spam.
Whenever a website is decided to be spam, then the owner will first be notified about the problem. If he/she responds and rectify the issue, he/she can again let Google know that the issue is fixed.
