Search Engine Optimization


Everybody in this world want their website or blogs to appear on the first page of search engines. Well, why not? After all they are here for marketing or provide information about something. Before I answer what is Search Engine Optimization, let me introduce what is a search engine first of all. A search engine is a Web server which contains links to various websites across the world, Google, Yahoo, Bing, Ask, Kosmix etc for example. Whenever a user wants to access some Website (when the exact URL is unknown), he enters a set of related words and the search engine displays related links to the user. Now, these words are called Keywords.


What is Search Engine Optimization(SEO)?

        To put it in simple words, let me give you an example. Suppose I create a Website regarding e-Commerce, just like amazon.com, flipkart.com, etc. During initial stages, neither my Website nor my company is well known to the customers. When the question of publicizing the Website comes up, Search Engine Optimization is of great help. If my Website is completely Search Engine Optimized, links to my Website appear in first page of the search engines.
Search engine optimization (SEO) is the process of improving the visibility of a web site or a web page in search engines via the "natural" or un-paid ("organic" or "algorithmic") search results.
       In other words, SEO is used to increase the page rank of a Website. Higher the page rank, probability of my website appearing in the first page of search engine is higher. This in turn, is proportional to the number of users visiting my website. It plays a vital role in Internet marketing.


How SEO works?

       The operations of SEO is based on certain rules. If the Webmaster follow these rules while creating the Website, rest of the work will be done by search engines.
Some of the rules are:

1. Home page and other landing pages of the Website must contain a 'title tag' which describes the website. This title tag is what we see when we search for some links in search engines. They appear on top of the browser when it is opened.
2. The description of each and every page must be specific. This description is called 'meta description' and this is what we see below the links displayed in search engines. Description is small paragraph that describes the content of the page.
3. Description and title tag must contain maximum but meaningful use of Keywords.
4. The content of the webpage must contain these Keywords in excess.
5. Link building is one of the popular methods, where in, appropriate links to other websites are provided from one site to another(external links), or within the site from one page to another(internal links).
6. Each page of a website shall have a unique URL.

There are many such rules to increase the page rank and hence the traffic of a Website. However, the above set of rules are mandatory.


First of all, the search engines must be made to crawl through our website. For this, we need to submit our sitemap to all the search engines. Google provides a handy tool called Webmasters for this, Yahoo and Bing can directly receive the URL and place in its directory. Search Engines might take some time to crawl through your website.

Google provides a tool called Google Adwords to analyze which keywords are being used by the users to enter my site. Being a good Webmaster, you can use the word which is most frequently used and place it in the title tag. This increases the popularity of you website.

SEO

After all this optimizations, you can verify the increase in the number of visitors to your website by using Google Analytics, again a Google tool to analyze where the traffic is coming from, how many users visited, how long they stayed back in your website etc. Also there are many websites for this type of analysis, for example, Alexa, Trafficwala etc.

Nowadays, SEO marketing is very useful and it is obviously used in almost all websites. However, all these pages does not appear on the first page. The reason for this is, search engine uses a complex algorithms to decide which website should be placed higher and which one to be lower.

Facebook is currently the top ranked Website in the world. Popularity of Facebook, in short FB, has made friends, students, officials, marketing managers, advertisers, turn towards Facebook to serve their individual purpose. In fact, Facebook has overtaken Google as the most popular Website recently, with a better page rank as well. It currently has over 350 million users across the Globe!
 
  • What is Facebook?
          Facebook is a social networking site through which members who has a profile on FB can link together and share information. Nowadays, FB is being used as educative, informative, advertising, marketing,  networking, recreation, stay-in-contact, campaigning etc. I guess you know more about Facebook than me!! Let me go on.


  • When and Why did the idea of FB arise?
          In 2004, Mark Zuckerberg, Dustin Moskovitz and Chris Hughes, three Harvard University students, launched a Web site designed to put students in touch with one another, share their photos and meet new people. They called it thefacebook.com, and before long the site became extremely popular on the Harvard campus. A month after the site launched, the creators expanded it to include students from Stanford, Columbia and Yale. By 2005, students in 800 college networks across the United States could join the network, and its membership grew to more than 5 million active users. In August of that year, the site's name changed to Facebook.com


  •  How Facebook works?
          Basically it has two ends: Front end and the back end.
Front end:
Facebook uses a variety of services, tools, and programming languages to make up its core infrastructure. At the front end, their servers run a LAMP (Linux, Apache, MySQL, and PHP) stack with Memcache.
Facebook runs the Linux Operating system on HTTP Apache servers. It uses a huge MYSQL database to store all the information and PHP to design Web interface and their operations. And Memcache is a memory caching system that is used to speed up dynamic database-driven websites (like Facebook) by caching data and objects in RAM to reduce reading time. Memcache is Facebook’s primary form of caching and helps alleviate the database load. Having a caching system allows Facebook to be as fast as it is at recalling your data. If it doesn’t have to go to the database it will just fetch your data from the cache based on your user ID.

Back end:
Facebook’s back end services are written in a variety of different programming languages including C++, Java, Python, and Erlang.
A list of all of Facebook’s open source developments can be found here. Some of the major ones are Thrift(protocol), Scrib(log server), Cassandra(database), HipHop for PHP.  Hiphop converts PHP to C++ program and Unix command 'g++' is used to compile the code. 


If you look past all of the features and innovations the main idea behind Facebook is really very basic—keeping people connected. Facebook realizes the power of social networking and is constantly innovating to keep their service the best in the business.

Google Instant has revolutionized Google search, when it was released last Wednesday. Google Instant search involves a mechanism of Stream searching, in the sense, your Google search page will be continuously monitored by Google from the back end. It analyzes the words you type in, and suggest most popular keywords that you may intend to search for. In LESS TIME than EVER!!!!

Google Instant
Google claims it saves 2-5 seconds per search.

According to analysis, people take around 300 milliseconds between keystrokes. Using Google Instant can lower this time to 30 milliseconds, a Google prediction.

Even when you are not sure what you are searching for, Google suggests you some searches when you type a word and give a pause. Now, the time taken for this suggestions to line up will be much lesser in Google Instant. Also, if you are sure about what you want to search, you can type the exact phrase and hit 'Enter'. I mean to say, old system of search still works!

Experts feel Google Instant can save millions of hours spent in searching. Google Instant domains are installed in U.S, UK, France, Germany, Italy, Spain and Russia initially. However, other users can still use it by logging in to their Google Account and use Google Search. Sooner Google will adapt Instant domains across the Globe!

Try Google Instant by following this link.
