History and Evolution of Search Engine Optimization
Google was officially launched in 1998
by Larry Page and Sergey Brin to market Google search, which has become the
most used web based search engine. They were students at Stanford University in
California, developed a search algorithm known as “BackRub” in 1996. In the
beginning times the search engine required the E-mail id of the user and took
almost 24 hours to get the information. In the early period the information
that contained was limited. They realized this backlash in 2001’s World TradeCenter attack, during this time many people across the globe went searching
about this incident, and didn’t get any information about it. It was huge defect
for Google because it wasn’t crawlable.
They overcome this by adding three processes
to the search engine.
·
Crawling: automated fetching of webpages
by a software process. A web crawler is a program or automated script which
browses the worldwide web in a methodical automated manner. This process is
called web crawling or spidering.
·
Caching: the activity if storing data
for free use, such as a copy of web page served by a webserver.
·
Indexing: process of adding webpages
into Google search.
They seek information from webmasters
who responsible for maintaining one or more websites. They concluded that
optimization can improve the search engine. Some people opposed this decision
but later they agreed. There are two kinds of optimization on page/on site
optimization, which is modification of content, quality, headline etc. during SEO.
Off page optimization, modification of outside of webpage as sharing, links,
submission, blogging etc . After publishing this correction the search engine
began face spamming. Google always look after for their trust values. So they
began to add more applications to Google.
Niche/Content specific
During Niche specific
period crawlers only focused on keywords. If the website contains more
repeating key words they get ranked. This updation of Google simply leads to
spam. Websites are only focused on keywords instead of a qualified content.
Keyword stuffing is a black hat SEO technique were we injecting keywords in the
content. White hat SEO is an ethical stuffing of keywords. But according to the
niche specific ranking system the websites began to stuffing the keywords in
each and everywhere in their site. Google began to control the content by
changing algorithms to maintain quality of the contents. So they changed their
terms from content specific to link specific.
Link specific
These
terms of Google simply reveals that the websites which has more link
connectivity from other websites get ranked. Link specific terms didn’t improve
the quality of the webpage .they only focused on getting links from others. It
leads to low quality content pages and sites which can effects the trust values
of Google. And most of the websites were ranked only because of their high
supports of links from others and also some of the sites started to sale the
links. These unauthentic ranking system leads to reduce the trust among
Google. The Google again changed their
terms to quality link specific
Quality link specific
These terms only support the websites which has link connectivity from a ranked qualified site. After introducing these systems the web sites get ranked only if they had qualified contents in their sites and having only ranked site’s links. Twitter, share button installing site, adobe-flash player installing links are example for 10 on 10 ranked websites across the world. According to Google page ranking is trust value towards the website. In the previous period, ranking updation occur more than three time, after 2013 there is no updation.
After
introducing this system websites began to sale qualified links again. To solve
this spam Google again changed and modified their algorithm to ‘passing the
juice’ SEO. It is the power that is considered to be passed to your site by
backlinks from any external or internal sites or pages. This power said to be a
vote for your website, when you receive a lot of such backlink powers your
passing juice score increases and which website sales more links get reduced
their ranking. To maintain site’s ranking or equity Google introduced an
attribution <ahref=”http;//www.google.com” rel=”no follow”>Google</a>.
Google developed advertisement programs ‘adwords’ as earning outcome from publishing ads in Google or blogs or other sites. Google ads are a prepaid service which will improve the quality of websites through publishing advertisements. Google gets money for each click “pay per click”, Google reduces coast in each clicks. Another advertisement program developed by Google is ‘Google adsense’ it’s an earning program websites publish their ads in their own websites or blogs, this in an affiliate program.
During 2009 Google done many modifications in
their algorithms to improve the quality,
achievements, and trust values. They introduced more features in their
search engine:
Pogo sticking:
pogo sticking phenomena is a promoting system which will ranks the website according to their interaction, the most visited sites gets ranked above and
shown in one step ahead and also demoted the least visited sites. Also shows
‘not relevant’ button for this least visited site during a person’s enquiry in
search engine. Google developed this suggestion to identify the low qualified
content webpages, but it won’t be worked in several times.
During
2010 Google gives more important to social media signal in their search engine.
At that time social medias are 80% interactive platforms, so the websites who
shares more information in social media’s get ranked. Gradually ranking is
calculated according to more visited sites in social medias and the website
gets ranked. When two websites get equal likes or supports from the costumer
Google consider the more interacted or visited sites or on the basis of person,
status, etc. this is known as influential
power. Also Google then considered relationship
based interaction building; which focuses on selective persons to share the
topic.
On
2011 Google developed another version ‘Google+’: when a person search a data in
Google and shared it to Google+, and then a person who is connected to or the
same person searched it again in Google show the previous searching results in
4th or 5th positions.
