As from the early 1990's, the idea of using highly visible sites in search engines brought valuable results in the business fields. Search
engine optimization is often about making small modifications to
parts of your website.
When
viewed individually, these changes might seem like incremental
improvements, but when combined with other optimizations, they could
have a noticeable impact on your site's user experience and
performance in organic search results. we all know that in earlier
days there were only minority users for internet , at the same time
amount
of available information was relatively small. Access was mainly
restricted to some areas only.
A Brief History of SEO
- Site directories were one of the
first methods used to facilitate access to information resources on
the network. First project of this kind was Yahoo and was opened in
April 1994. But it did not actively seek out resources.
- Brian Pinkerton creates the first crawler named Web crawler to index entire pages and this project was started in 1994 and was the first full-featured search engine.
- Lycos was launched in 1994 and is one of the earliest crawler based search engine.
- In 1995 Lycos and AltaVista search engines appeared. For many years Alta Vista was the major player in this field
- Sergey Brin and Larry Page created Google as a research project at Stanford University in the year 1997. The most popular search engine in the world is Google.
- At present Google, Yahoo and MSN Search are three leading international search engines with each having their own databases and search algorithms.
- In 1999 altavista relaunches its website and changes its algorithm,as a result lots of sites disappear.
