Google

Google - the most popular Internet search engine, owned by Google Inc., an American corporation.

Google's name is derived from the misspelled (specifically or
accidentally) by one of the makers of the English word googol, which
means ten to the hundredth power. From the name Google has developed a verb to google - guglować, guglić, guglać (all forms are correct), meaning the search for something on the Web using the Google search engine.
Since Google is the most popular search engine in the world, a priority
in the process of positioning is to gain the trust of Google
Positioning page.

The history of the

Google Search was created in March 1996 by Stanford University
students, Larry Page and Sergey Brin, in the work of the Digital Library
Project.
September 15, 1997, he officially domain google.com was registered, and
the following year was created corporation Google, Inc.. At the end of 1998 Google's crawler about 60 million crawled web pages. Google is constantly developing and improving. Search algorithms are updated on average 300 times a year, and the amount of features and services are rising.

Indexing pages
In the process of indexing (scan pages in order to introduce them to the database) Google uses special crawlers:

Googlebot - the main robot that scans the content of the page in order to create a search engine's index. - Googlebot-Image - scans the page content to index images.

Mediapartners-Google - scans the content of your pages for the presence of AdSense ads.

AdsBot-Google - checks for quality content pages that AdWords ads are placed.

Googlebot-Mobile - indexed web portals for mobile devices.

Google Search Appliance - is responsible for the indexation of the Google Search Appliance devices.

There are two primary theories of indexing:

"Sandbox effect".
The essence of this phenomenon is that Google places specific pages
(those that have new domain names, the young sites) in the so-called
sandbox (waiting area), where the parties are located until the system
deems them ready to appear in the search results.

The opposite theory, which says that the new party is assigned a high PageRank and high positions in search results. Typically, this privilege working soon - until the real parameters of the test.

In order to avoid placing the works in the Google sandbox, avoid too
rapid acquisition of external links for the "new service" and gradually
acquiring links from trusted sites, so that the process looks natural to
the search engines.

Create a page ranking

One of the most important factors that influence the order of the pages
in the Google search results (as determined on the basis of their
credibility, presumably, stability, etc.) is the PageRank indicator or
simply LP (named after the creator, Larry Page `s - co-founder of
Google) - the number of specifying the value of the by Google. The PR entire site adopted to recognize LP's main page. PR value can be between 1 and 10 High PR is one of the guarantors of the emergence of the highly in search results. The term PR side affects mainly the quantity and quality of links leading to it. Google did not disclose the exact algorithm for calculating PageRank, and hides data on the frequency of updates. As of today, is one of a number of parameters (it is believed that there are over 200), affecting the position of the hand.
Important is the degree of relevance of the page, the inner contents
and code optimization, quality and quantity of links, and other factors.
Google provides its users the ability to use a variety of services. Among other things, these are:

Google Search (search) - the main Google.
The search is based on the content of the pages also scans files in
PDF, RTF, Flash SWF, PostScript, Microsoft Word, Microsoft Excel,
