1. Search Engine Optimization

2. HISTORY OF SEARCH ENGINES
The need for search engines was first noted in 1945 when American engineer and
scientist Vannevar Bush published an article in The Atlantic Monthly, emphasizing
the necessity for an expansive index for all knowledge.
The Archie (named for "archives") is the very first search engine created in 1990, was
designed to search and store directory listings on file transfer protocol sites. Below
are the search engines developed from 1990 to present:
• Archie (1990) was the first tool created by Alan Emtage and L. Peter Deutsch for
indexing, and is considered the first basic search engine.
• Lycos (1993) was created as a university project, but was the first to attain
commercial search engine success.
• Yahoo! (1994) started at Stanford University by Jerry Yang and David Filo (both
electrical engineering grad students) that became a web portal and search engine.

5. BACKRUB – A Predecessor
of Google
BackRub was an early search engine from the 1990s which is now regarded as the
predecessor of the Google search engine. It was personally developed and operated
by Google founder Larry Page and Sergey Brin.
The roots of Backrub
Work on the BackRub search engine began in 1996. It was a research project of Larry
Page, who studied at Stanford University at the time and was part of the team that
worked on the Stanford Digital Library Project (SDLP). This project had set itself the
goal of developing technologies which could create a universal digital library. As
part of his thesis, Larry Page took up the issue of linking. His reflections on
understanding link structure as a huge graph, later led to the development of the
still significant PageRank algorithm.

Development
Page named his project BackRub. Later, Sergey Brin, who had also worked on a
similar study and research area, joined Page and from then on supported him in the
development of the search engine.
First, the search engine returned a list of backlinks, whose ranking was designed
depending on their importance. The two developers quickly realized that a search
engine that would be based on PageRank would yield better results than existing
technologies. At that time, search engines were exclusively fixated on how frequently
a searched keyword appeared on a web page. Page and Brin wanted to build
BackRub on the principle that the websites which had the most links would be the
most relevant.

Growth
After Backrub began indexing websites in March 1996, the index grew very quickly.
By August 1996, some 75 million pages had been indexed which occupied a total of
207 GB when combined. Around 30 million HTML pages were among them, but
even more e-mail addresses. In the year Google was created, Backrub had already
indexed 25 million pages. Google Inc., was finally established on September 4, 1998
and the renaming of the search engine from Backrub to Google was decided.

Importance for search engine optimization
With the search engine Backrub, Page and Brin laid the foundation for search engine
optimization as it is known today. For many years, the targeted building of links was
an elementary building block of SEO to improve ranking. Backrub, or more
specifically their founders, can be credited with the fact that the number of external,
incoming links influences ranking.

9. WHAT IS SEO?
SEO stands for Search Engine Optimization, which is the practice of increasing
the quantity and quality of traffic to your website through organic search engine results.
To understand the true meaning of SEO, let's break that definition down and look at the
parts:
1. Quality of traffic. You can attract all the visitors in the world, but if they're coming to your
site because Google tells them you're a resource for Apple computers when really you're
a farmer selling apples, that is not quality traffic. Instead you want to attract visitors who
are genuinely interested in products that you offer.
2. Quantity of traffic. Once you have the right people clicking through from those search
engine results pages (SERPs), more traffic is better.
3. Organic results. Ads make up a significant portion of many SERPs. Organic traffic is any
traffic that you don't have to pay for.

10. HOW SEARCH ENGINE WORKS?
The work of the search engine is divided into three stages, i.e. crawling, indexing and retrieval.
1. Crawling - Process of fetching all the web pages linked to a website. This task is performed by a
software, called a crawler or a spider (or Googlebot, in case of Google).
2. Indexing - Process of creating index for all the fetched web pages and keeping them into a giant
database from where it can later be retrieved. Essentially, the process of indexing is identifying the
words and expressions that best describe the page and assigning the page to particular keywords.
3. Processing - When a search request comes, the search engine processes it, i.e. it compares the
search string in the search request with the indexed pages in the database.
4. Calculating Relevancy - It is likely that more than one page contains the search string, so the
search engine starts calculating the relevancy of each of the pages in its index to the search string.
5. Retrieving Results - The last step in search engine activities is retrieving the best matched results.
Basically, it is nothing more than simply displaying them in the browser.

11. WHAT IS ON-PAGE AND OFF-PAGE SEO?
Conceptually, there are two ways of optimization:
1. On-Page SEO - In this type of SEO, we generally optimize our website. It includes
providing good content, good keywords selection, putting keywords on correct places,
giving appropriate title to every page, etc.
2. Off-Page SEO - It includes creating quality back-link(link building) of our website on
other websites which are popular and have good traffic on search engines.

12. TECHNIQUES OF SEO
SEO techniques are classified into two broad categories:
1. White Hat SEO - Techniques that search engines recommend as part of a good design.
2. Black Hat SEO - Techniques that search engines do not approve and attempt to minimize
the effect of. These techniques are also known as spamdexing.
