EVOLUTION OF SEO           

Google came as a search engine. In early stages it was not working on basis of algorithm, but on the content basis. It was like ranking the pages on basis of more number of same keywords used. So a new process called keyword stuffing [repeating keywords to gain page rank easily.it is a black hat SEO process] started in order to gain  more ranking for the page. 

Google found more opportunities and started to work on it .Consequently  google changed the content based search to link based to maintain the quality of data attained.. Gradually  google found it to be failing in keeping its quality. Many black hat process where done to rank the webpages. Example: link were sold for cash. 

          Then link specific was changed to quality link specific [links from a trust worthy page] ranking method. Only quality links attained will be ranked. The links attained from other websites are considered as vote of recommendation. These links are called as backlinks.  Here a new term called page ranking was formed  

Page rank: Determines the quality rank attained by a quality link.it is also called trust value.                                                                                                                                          

Trust value grows as long as a search remains in page. Page will increase with the growth of trust value. example trust value gained is high for pages like twitter.com and US government site.

Page rank updation was last done on 2013 and on 2019 it was stopped completely or can also be told that google refreshed it. Another  update done during quality link specific era was passing the juice.

Passing the juice

It is the term used to determine the equity passed through hyperlinks.. if a webpage with high ranking, passes equity or links to other pages, it will loose its page rank.

In the year 2005, google joined yahoo and Msn for the “no follow attribution”. This was an action which was used by the web pages to pass the equity or share there links without loosing there page rank.

According to the click on the ads on the vlogs, a small amount will be paid to the vlog owner from the CPC paid to google. Google suggest and Google personalized search was enlightened in the year 2009. Google became more interactive during this year. As a result of interaction more updations like bounce rate and pogo sticking were done, to maintain the quality of the webpage.

Bounce rate: It is very important for webpage to keep its bounce rate always low, to maintain its page rank. Bounce rate is the percentage of visitors who leaves or bounces away from the webpage, after viewing it once, it means not much time is spend on that page,  because the page is not giving better search results to the users and thus bounce rate will increase, this result in loss in page rank.

Pogo sticking:  when the searcher clicks on a link on search engine result page, and finds that its not the page needed and immediately moves back towards the search page, and moves to the next search result or new page. Then the ignored page may be pushed down in search engine result. The links which are not easily opened in search result are called broken links.
