Sandbox - Google Sandbox

Sandbox is term we generally use to hear in computer security.In computer terminology , we say it is a security mechanism or tool  for separating running programs because of their uniqueness.so that it won't effect other programs flow.

what we are going to discuss is what is sandbox effect in seo. how it is effecting the seo optimization.
or how it is related to Google.Sandbox is  a name given to an observation about how Google rank web pages in its index.

so coming to Sandbox effect?why now a days we are talking about this is - The sites which are getting more back or inbound links from high page rank sites are going to Google Sandbox.Based on observations, It have an effect of  drastic fall of position in Google SERP's and so that it is not easy to get good position again.

They are saying their own version for this effect, they would call it as a Restriction on new sites, which will be indexed and getting high position in SERPs in short span of time.They call it as restriction for 3 months, to eradicate the spam sites being listed in SERPs.

Recently we have been seing more queries  regarding  this effect on their sites. Normally for the sites which are getting 2 or more backlinks  PR 6 sites are getting into sandbox.It would be like a probation period for the new sites, which want to be listed in top position in short span of time.The links which are natural , it won't have any effect.Because now the Google Algorithm is changed and giving more importance to the  Fresh content.

Search Engine Major Goals

Search Engines follow their own criteria for searching the web.Search Engine crawl the web through specific parameters.

In Search Engine crawling , they crawl the web mainly by checking the html codes of pages. They see the meta tags of the page. Depending upon the description they crawl the respective page and it also crawl all the links to that page. So it will collect all the pages and check the duplication of links in the step.

The next step Indexing i.e.,after collecting all the pages, it will index the pages based on the particular phrase or key word in the database and it will arrange pages based on the specific terms and their synonyms.

The next step is Querying i.e., responding to user queries is main aspect of Search Engines. How fast it can respond to the user queries is given main importance. So that , the data should be relevant and appropriate . so that he can visit again and again further in future for any thing. It will respond to the queries with giving options for searching for  a particular word or word + some extra.So that it will give flexibility to the users search for  a wide info with a single click.

The next step is Ranking i.e., ranking of a site or web page .so it's purely based on the algorithm of the Search Engine it follows. Every search engine follows their own algorithm to rank a website . Mainly the check the Quality Content and meta tags and proper linking of internal pages etc..in ranking a website. 

example:- Google is giving ranking to a websites.it's ranking is purely based on their priority and rules they follow.

so we will discuss it later when we discuss about page rank.

How Search Engine works?

It is really important to know how Search Engine works before doing any SEO work. because unless you know how it works? you are not able to do understand the real meaning of Optimizing the Search Engine.

so let's start our discussion from Search Engine work.Later we will discuss the Directory work structure.

                                

I would say we have a lot of Search Engines available world wide...google, inktomi, baidu(china), naver(korea), alltheweb. Does every search engine follows same strategy ?If so what is the pros  & cons.

Generally individually every Search Engine has their own algorithm. It follow their work based on them. Generally search engines update the database for 3 months.
So major goals and functions of Search Engine would be:
 1) Crawling of the web pages based on search engine algorithm.
 2) Indexing the web pages by selecting proper content on specific keyword.
 3) Responding to the user queries by relevant pages.
 4) Ranking of the pages .

Search Engine Vs Directories.

Lets us start our discussion with what is Search Engine? 
    
Search Engine  is internet based  tool that searches an index of documents for  a particular term, phrase or text specified by user.Other wise we say it is  a software program that searches a database  and reports information that is related to specific term.
Examples of Search Engines : Google, inktomi, altvista ,alltheweb and msn.
A Directory is website which looks just like a search engine but organised as a series of sections or categories  under which appropriate sites are filled.so Directory is divided into  specific categories and sub categories.
Examples of Directories : yahoo, dmoz.org, gimpsy.
So the main basic purpose of Search Engine & Directory is "to help people find websites of interest to them".

Let us discuss the what is difference between Search Engine and Directories:
1.Search Engines are run by robots where as Directories run by human Editors.
2.Search Engines are free to get listed in and they never charge for it.where as some directories are free and some will charge  money for each submission.
3. Search Engines are more popular and used because of their convenience.
All people have do is just type a keyword in search engine relevant sites come up.
                     vs
 Directories are less popular because of their way of organizing data. In Directories we have to go  through the specific categories and sub categories.
4.Search Engines some times disorganized when someone visits a website.but directories always have listings grouped together by topic.
