History and Evolution of SEO

                         History and Evolution of SEO


                   Google was founded by Larry page and team in 1998 as their PhD project. In the beginning, when a user search in google, the result was given back to them in 24 hours through their email. Later expand the facility by giving instant search results. 
The triggering point to the rapid growth of google was the world trade center terrorist attack of 11 September 2001. The people from all over the world enquire about world trade center in google search engine. But Google couldn’t give enough information about the world famous construction.This incident made them think about the issue. They took it as a serious issue and conducted a meeting to discuss on the same and to solve the related issues. They discussed why they were unable to provide enough information  and found that most of the websites were unable to crawl by google due to huge size of websites. They found a solution for crawling and to enlarge the database by sharing the guidelines to optimize the website to the webmasters. If the webmasters  follow the guidelines google, will be able to crawl maximum number of websites and can enlarge the database.


SEO (Search Engine Optimization)


Search engine optimization (SEO) is the process of affecting the online visibility of a website or a web page in a web search engine's results. It is the process of getting traffic from the free, organic, or natural search results on search engines.

On-page optimization


In the search engine optimization, on-page optimization refers to factors that have an effect on  Web site or Web page listing in a search results. These factors are controlled by you or by coding on your page. Examples of on-page optimization include actual HTML code, meta tags, keyword placement and keyword density.

Off-page optimization


In search engine optimization, off-page optimization refers to factors that have an effect on the Web site or Web page listing in natural search results. These factors are off-site in that they are not controlled by you or the coding on your page. Examples of off-page optimization include things such as link popularity and page rank

Search engine works based on crawling, Caching and indexing


  • Crawling : Crawling is the process of scanning the websites to get information about that website. After taking snapshot it is saved in the database.
  • Caching   : caching is the process of fetching information from the website and storing it in the database.
  • Indexing  : Indexing is the process of listing the fetched web pages. 


PageRank


Page-rank  is the trust value of websites ranked by Google. Page-rank is a way of measuring the importance of website pages. 
Google takes 200+ factors into consideration to determine the rank of webpages. Google has not exposed all the quality factors.
Page-rank evaluates the quality and quantity of links to a webpage to determine a relative score of that page’s importance and authority on a 0 to 10 scale.


Passing the Juice


When a website with high page rank give more number of links to other website with lower page-ranks, the page rank of  the website decreases. The website should have a balanced link juice distribution to maintain the best page rank.


rel=”no follow”


rel="Nofollow" provides a way for webmasters to tell search engines "Don't follow links on this page" or "Don't follow this specific link." Equity wont pass if we add rel=”nofollow”
<a href=www.sooftloom.com rel=”nofollow”>softloom</a>


During the period 2003 to 2008 Google made some drastic changes in the algorithem, But they did it with fear. Introduction of Google add words was one of the move they made during the period. 
Google AdWords is an online advertising service developed by Google, where advertisers pay to display their advertisement in the google. AdWords is one of the Google's main source of revenue. 

AdWords offers services such as pay-per-click (PPC) advertising in which an advertiser has to pay when the ad is clicked.
The very next advertisement method they introduced was the Adsense. After 2008, Google introduce many free social media websites like Orchud, Youtube, Gmail etc.
In 2009 they came up with a very powerful updation, Personize search in which the search engine gives the search suggestions according to the person using the web.

Then google made an updation in 2009 such that the ranking of a website is based on the response in the website. 


Pogo sticking




When a user selects the website A and suddenly closes it in seconds and then opens an Website B and spends more time on it, the google will rank the website B more than A. It can also be  the problem with page loading or attracting the wrong audience, Google and other search engines will come to the conclusion that your page is ranking by mistake and makes your rank drop. 
In 2010 google took social media as a ranking weapon due to the influence of the social media in the society.
After 2011 they understood the need and importance of quality search engine and made many drastic changes in the algorithm.
