Search Engine Overview

1.Primary Search Engines
 

Overview of Google

Each of the major search engines differs in some small way. Google is the king of search engines, in
part because of the accuracy with which it can pull the results from a search query. Sure, Google
offers all kinds of extras like e-mail, a personalized home page, and even productivity applications,
but those value-added services are not what made Google popular.
What turned Google into a household word is the accuracy with which the search engine can return
search results. This accuracy was developed when the Google designers combined keyword searches
with link popularity. The combination of the keywords and the popularity of links to those pages
yields a higher accuracy rank than just keywords alone.
However, it’s important to understand that link popularity and keywords are just two of hundreds
of different criteria that search engines can use in ranking the relevancy of web pages.

Overview of Yahoo!
Most people assume that Yahoo! is a search engine, and it is. But it’s also a web directory, which
basically means that it’s a list of the different web pages available on the Internet, divided by category
and subcategory. In fact, what few people know is that Yahoo! started as the favorites list of
the two young men who founded it. Through the acquisition of companies like Inktomi, All the
Web, AltaVista, and Overture, Yahoo! gradually gained market share as a search engine.
Yahoo!, which at one time used Google to search its directory of links, now ranks pages through a
combination of the technologies that it acquired over time. However, Yahoo!’s link-ranking capability
is not as accurate as Google’s. In addition, Yahoo! also has a paid inclusion program, which some
think tends to skew search results in favor of the highest payer.

Overview of MSN
MSN’s search capabilities aren’t quite as mature as those of Google or Yahoo! As a result of this immaturity,
MSN has not yet developed the in-depth link analysis capabilities of these other primary search
engines. Instead, MSN relies heavily on web-site content for ranking purposes. However, this may
have a beneficial effect for new web sites that are trying to get listed in search engines.
The link-ranking capabilities of Google and Yahoo! can preclude new web sites from being listed for
a period of time after they have been created. This is because (especially where Google is concerned) the quality of the link may be considered during ranking. New links are often ignored until they
have been in place for a time.
Because MSN relies heavily on page content, a web site that is tagged properly and contains a good
ratio of keywords will be more likely to be listed — and listed sooner — by the MSN search engine.
So, though it’s not the most popular of search engines, it is one of the primaries, and being listed
there sooner rather than later will help increase your site traffic.


2.Secondary Search Engines

Secondary search engines are targeted at smaller, more specific audiences, although the search engine’s
content itself is still general. They don’t generate as much traffic as the primary search engines, but
they’re useful for regional and more narrowly focused searches. Examples of secondary search engines
include Lycos, LookSmart, Miva, Ask.com, and Espotting.
Secondary search engines, just like the primary ones, will vary in the way they rank search results.
Some will rely more heavily upon keywords, whereas others will rely on reciprocal links. Still others
might rely on criteria such as meta tags or some proprietary criteria.
Secondary search engines should be included in any SEO plan. Though these search engines might
not generate as much traffic as the primary search engines, they will still generate valuable traffic
that should not be overlooked. Many users of secondary search engines are users because they have
some loyalty to that specific search engine. For example, many past AOL users who have moved on
to broadband Internet service providers still use the AOL search engine whenever possible, because
it’s comfortable for them.


3.Targeted Search Engines

Targeted search engines — sometimes called topical search engines — are the most specific of them all.
These search engines are very narrowly focused, usually to a general topic, like medicine or branches
of science, travel, sports, or some other topic. Examples of targeted search engines include CitySearch,
Yahoo! Travel, and MusicSearch, and like other types of search engines, ranking criteria will vary from
one to another.
When considering targeted search engines for SEO purposes, keep in mind that many of these
search engines are much more narrowly focused than primary or secondary search engines. Look
for the targeted search engines that are relevant to your specific topic (like pets, sports, locations,
and so on).

Distinguish Ethical and Unethical SEO Practices

Search engine optimization in organic way is a little bit hard but interesting webmasters should understand the way that search engines like,simply mean search engine friendly design and practice with the web to getting higher rank and more simply the ethical or white hat seo practices and work with web sites,because search engines don't like the bad practices they counted those things as spamming and that spamming can be dangerous and harmful for website owners and for the business to which web is affecting.
When you will start to do seo you should keep somethings in mind that what can you do with the web and what can not do.      
So what exactly should and should not you do? There’s a list. Here is part of it.

You should do:

1. Create a web site that contains meta tags, content, graphics, and keywords that help improve your site

ranking.

2. Use keywords liberally on your site, so long as they are used in the correct context of your site topic and
content.
3.Include reciprocal links to your site from others as long as those links are legitimate and relevant.
4. Encourage web site traffic through many venues, including keyword advertising, reciprocal links, and
marketing campaigns.
5. Submit your web site to search engines manually, rather than waiting for them to pick up your site in the
 natural course of cataloging web sites.

You should not do:

1. Trick search engines by imbedding hidden keywords in your web site. This is a practice that will very likely
get you banned by most search engines.
2. Artificially generate links to your site from unrelated sites for the purpose of increasing your ranking based
on link analysis. Most search engines have a built-in mechanism that will detect this type of deceptive practice.
3. Artificially generate traffic to your web site so that it appears more popular than it is.Again,there are    safeguards in place to prevent this from happening, and if you trip those safeguards,you could end up on     the banned list for many search engines.
4. Force your web site to appear in search engine rankings by submitting the site repeatedly for inclusion in the rankings. A good general rule of thumb is that you should submit your site once and then wait at least six
weeks before submitting it again. Submitting it repeatedly will, again, only lead to something nasty like being
banned from the search engine.
5. Expect search engines to automatically rank you at the top of your topic, category, or keyword as soon as
the site is picked up. It could take a little time to build the “status” that you need to reach a high search engine ranking. Remember, SEO is a process.

Understanding Search Engine's Behavior

What is a Search Engine?
Basic concept of search engine is to type a word or phrase into a search box, wait a few seconds and references will appear, and all we have to do is click through those pages to find what we want.But exactly the search engine has a back end which is a piece of software that uses applications to collect information about web pages. The information collected is usually key words or phrases, the information is then indexed and stored in a database. On, the front end, the software has a user interface where users enter a search term- a word or phrase.

Structure of a Search Engine:
         
This is a vitally important to succeeding with search engine optimization (seo).

Query Interface:
This is the page that users see when they navigate to a search engine to enter a search term. Today many search engines have added much more personalized content in an attempt for search engine marketing.

Crawlers, Spiders, and Robots:
These little creatures are programs that literally crawl around the web, cataloging data so that it can be searched, like this many SEO’s work in a team and view the search engine behavior by using the search engine characteristics.

Databases:
Every search engine contains or is connected to a system of databases, where data about each 
URL in the web is stored.

Search Algorithms:
Generally a search algorithm is a problem - solving procedure that takes a problem, evaluates a number of possible answers, and return the solution to that problem. There are several types of search algorithms, they are:-
        
List search
Tree search
SQL search
Informed search
Adversarial search
Constraint satisfaction search

Retrieval and Ranking: retrieval of data is a combination activity of the crawler (or spider or robot), the database, and the search algorithm. Those three elements work in concert to retrieve the word or phrase that a user enters into the search engine’s user interface
Ranking plays a large part in search engine optimization. Most search engines employ methods to rank the results to provide the best results first. Different search engines use different ranking criteria, they are :-
          
Location : Location describes the location of keywords where the target keywords are placed at the
                  document.

Frequency :  Frequency describes that how many times a keyword appears in the document.
 
Links : Links describes that how many links are for that keywords in the form of Anchor Text(In/Outbound).

Click-troughs : How many clicks a key word collects.It can be see by using analytical tool such as Google Analytics. 

Thus, we see that two search engines that have evolved: one is predefined and hierarchically ordered keywords. The other is the system that generates an inverted index by analyzing texts it locates
Most search engines are commercial ventures supported by employing SEO’s which brings qualified traffic  from the search engine and provide search engine marketing by truly understanding what exactly is the search engine characteristics.
Characteristics of Search:
The characteristics of search refer to how users search the internet. This can be everything from the heuristics they use when creating a search term to the selection the user makes (and the way those selections are made) once the search results are returned. This means different search results are returned depending upon the query, even if using the same search engines.
Today many people search the internet for several purposes depending on what are their needs and what they want.
This wealth of search engine users is fertile ground SEO targeting. This ensures the SEO to understand the search engine characteristics for the search engine optimization.
By using the search engine behavior the SEO can know what the users need and what are their views about the results that are placed in front of them.

Some Major Search Engines:
             
The major search engines are:
                      
Excite-1993
Yahoo-1994
Web crawler-1994
 Lycos-1994
 Infoseek-1995
 AltaVista-1995
 Inktomi-1996
 AskJeeves-1997
 Google-1997
 MSN Search-1998
              
Search engines can be broken down into three different types-
                          
Primary search engines: a primary search engine is the most often used search engines. Ex: yahoo, Google and MSN are primary or major search engines. These will generate the majority of the traffic to the web site and primary focus of SEO as it is shows the search engine behavior. Additional features like e-mail, mapping, news and different entertainment applications are also available from most of the primary search engines. They provide better results which must be kept in search engine optimization.

Secondary search engines: they are targeted at smaller, more specific audiences, although the search engine’s content itself is general. They don’t generate as much traffic as the primary search engines, but they are useful for regional and more narrowly focused searches. Ex: Lycos, LookSmart, Miva, Ask.com, and Espotting. These are just like primary search engines, will vary in the way they rank search results. Some will rely more heavily upon keywords, whereas others will rely on reciprocal links. This should be included in any SEO plan. Though they don’t generate much traffic as primary search engines but they generate valuable traffic that should not be overlooked.

Targeted search engines: these search engines sometimes called topical search engines are the most specific of them all. These are very narrowly focused to a general topic, like medicine, travel sports or some other topic. Here ranking criteria will vary from one to another. Ex: CitySearch, Yahoo! Travel, and MusicSearch. This is helpful for SEO for specific and much more narrowly focused topic which they want. They can use it for more specific search.


Putting search engines to work:
             
A search engine works in the following order:

Web Crawling
Indexing
Searching
                
All search engines go by the basic process. But different search engine use different methodologies and are bound to display different results depending on which search engine is used.
         1) The searcher types a query into a search engine.
         2) Search engine software quickly sorts through literally millions of pages in its database to find  
              matches to this query.
         3) The search engines result are ranked in order of relevancy.     
Search engines work by strong information about many web pages, these pages are retrieved by a web crawler. The contents of each page are then analyzed to determine how it should be indexed in a database for use in later queries. When a user enters a query into a search engine, the engine examines its index and provides a listing of best-matching web pages. These results are stored by using different methods by different search engines and are ranked accordingly.

This is the vital step in search engine optimization, as the search engine behavior is concerned it helps to know the view placed in front of them.
For the SEO this is the important part as through this they can bring great traffic to the user if search engine works properly and efficiently.
In this search engine when a user enters a query then the search engine characteristics could be well understood.
So now a days the big ventures are employing into search engines optimization and going for search engine marketing which will help their sites grow and their business also.
  
Elements Needed For SEO  

Search engine optimization is essentially the science of designing your web site to maximize your search engine rankings. This means that all of the elements of your web site are created with the goal of obtaining high search engine rankings.

Those elements include:

1.Entry and exit pages
2. Page titles
3. Site content
4. Graphics
5. Web site structure

In addition to these elements, however, you also have to consider things like keywords,links, HTML and meta-tagging. Even after you have all the elements of your page optimized for search-engine friendliness, there are other things to consider. For example, you can have all the right design elements included in your web pages and still have a relatively low search engine ranking. Factors such as advertising campaigns and update frequencies also affect your SEO efforts.
 

All of this means that you should understand that the concept of search engine optimization is not based on any single element. Instead, search engine optimization is based on a vast number of elements and strategies. And it’s an ongoing process that doesn’t end once your web site is live.

Google Search Technology

Google patented the Pigeon Search Technology which is originally introduced by B. F. Skinner.
Google generally think that common gray pigeons are enough smarts and have unique capacity to distinguish objects.The common gray pigeon easily distinguish the objects in minute differences,it have great capability to differentiate and select relevant web site which contains the relevant constants among hundred thousands of websites with similar pages.

When a Google user start searching I mean when a user submitted a query than it passes to server as I mentioned on my previous post Google Search,at the server side the monsters flashes the search results very fast and however a very close and relevant result or web page is founded by any one of pigeon from the cluster it hits by pigeons beck which is rubber coated steel bar and its assign the Pigeon Rank Value for a page and Pigeon Page Rank is depend on kisses of pigeons for a web,in simple the web page which collects more kisses from pigeons is getting higher Pigeon Page Rank and that is the only way to get higher page rank .
The Google is the search engine which is fully crawler based not human edited so there is no place for spamming and forgery because you will be penalized and banned by Google.The web doing spamming can not do well with Google.

Google have great technology for fast and accurate search and it is based on Pigeon Search.

Thanks

Google Search

Google search is very fast and too closer to relative keywords but how it works most of the user and web masters are unaware from it.I just do a try to describes how it works?When a user hit search tab for a specific keyword or keyword phrase than the query is simply pass to the web server and than web server pass this query to the nearest Index server and a index server contains the index content, it means index server describe the index of the page or content which matches the query,we can understand the role of index server by an example simply,A book have many page so to find a specific topic or page we need to see index at the back of book same as index server respond to the query and shows the index of that particular keyword or phrase and send this request to the doc server.
The query travel from index server to the Doc server which contains the snippets of the pages and retrieves the snippets of relevant page,the pages which contain the most relevant data are send to the users browser as a search result in a second of frictions.So the path of a query is looks like that.....

Query(Request)>>Web Server>>Index Server>>Doc Server>>(Response)User Browser.

Google is not only a search engine it is a technology itself. I am one of a fan of Google so i just want share this story with all other Google fans.

Every thing you wants to know about Google.
