Importance of robots.txt file

First some back ground on search engine robots

Web indexing robots are used by many search engines such as Google, Inktomi, AltaVista and others. These web indexing robots are also known as spiders. These spiders/robots are the tools used by engines to harvest data for their search engines. When you submit your website to the engines, you are effectively asking the search engines to send their web indexing robot to your website so that it can be crawled and added to their database.





So why do i need a robots.txt file?

Web-Indexing Robots can be controlled as to which part of your site they index by installing a simple text file called robots.txt in the root path of the server with explicit instructions on what the spider is and is not permitted to index on your website.
You can define which paths are off limits for spiders to visit an block off such . This is useful for such things as large directories of information, personal information, and parts of the website containing large amounts of recursive links, among others.
Now it is possible to include robots.txt indexing information directly in your meta tag and in some cases this is preferable if only one page needs to be controlled. You can use a meta tag like this meta name="robots" content="INDEX,FOLLOW> to tell the robot it is ok to index this page and follow links it finds on this page. However, if you have whole directories and multiple pages you want to control the indexing of then you need a robots.txt file to ease the burden of managing this task.




How accurate does my robots.txt tag have to be?

You need the correct path of the files or directories that reflect the web viewable path of the server.
Example: many servers use htdocs as the web root, but the ftp root will be different. Your robots.txt tag should not include the htdocs directory in front of the file/directory because the htdocs folder is not viewable on the web...the files in the htdocs are what need to be listed if you whish to control the spiders indexing of them.

Do I have to have a robots.txt file in order to have search engines index my site?

The short answer is no! A web indexing robot will crawl your site unless told not to. However lets go a little deeper than that. A good web indexing robot such as Googlebot or Slurp (Inktomi) are considered well behaved web spiders and will attempt to find your robots.txt file before it indexes your site. As well good robots will look at your meta tags file and check for the The advanced way in stopping malicious spiders that ignore or disobey your robots.txt file is to look at blocking users agents at the server level and even so far as blocking IP's etc where possible. A user agent is a signature that is attached to the robots (provided they added one) which can be used to identify the robot. When a page is requested from your web server, software such as IIS (windows server) or Apache (Linux/Unix) will store this user agent information in your log files which you can review and react accordingly.

Data Communication

The concept of data communication - transmitting data between two different places, connected via some kind of electromagnetic medium, such as radio or an electrical wire - actually predates the introduction of the first computers. Such communication systems were typically limited to point to point communication between two end devices. Telegraph systems and telex machines can be considered early precursors of this kind of communication. The earlier computers used the technology available at the time to allow communication between the central processing unit and remote terminals. As the technology evolved new systems were devised to allow communication over longer distances (for terminals) or with higher speed (for interconnection of local devices) that were necessary for the mainframe computer model. Using these technologies it was possible to exchange data (such as files) between remote computers. However, the point to point communication model was limited, as it did not allow for direct communication between any two arbitrary systems; a physical link was necessary. The technology was also deemed as inherently unsafe for strategic and military use, because there were no alternative paths for the communication in case of an enemy attack.

LIQUIDITY CRUNCH- A MAJOR PROBLEM FOR THE ECONOMIC PROGRESS

Procurement of excessive revenues of over Rs.100000 crore may be an extravaganza for the government which had already been running into deficits, but simultaneously it is also breeding liquidity crunch in the markets. Bunch of telecom players which have been rampantly vying to win over the 3G licenses are willing to pay as much as to remain afloat in competition with the telecom players. For this they have resorted to heavy loans which resulted in bringing about the liquidity squeeze in the financial markets. In order to finance such loans, banks have resorted to availing the call money loans and have started diverting their finances from the liquid mutual funds to fund the loan requirements of the telecom players. Commercial banks which used to be the prime lenders have become the net borrowers even further aggravating the liquidity problems in the Indian markets. About 5000 crores have been taken by way of Certificate of Deposits. PNB raised over 1100 crores at 6.30% interest for 3 months, State Bank of Hyderabad raised over 51000 crores from RBI @ 5.25%, Canara bank raised over 525 crore, UCO Bank 400 crores.
Such liquidity problem was further aggravated by the Euro crises which had its enormous impact over the Indian markets which tumbled down to close at 4807 on 24th May; 2010. This was because of the fears that the euro crises likely to have its impact globally and FII’s started pulling back their funds from the market on account of such fears.
This liquidity problem is expected to continue further until sincere efforts are put in by the government to make the funds available where they are in demand. Lack of money to fulfill the aggregate demand shall have its ill effects in giving rise to the inflationary expectations in the economy. Where on one hand the Central Banks are contemplating with an idea to increase the reserve rates more in order to tackle the inflation, on the other hand liquidity problem would make such efforts futile.
Liquidity problem is expected to prevail for some more time to come till the funds are being made available to the government in the form of the advance tax payments. However, RBI is trying to deal with the situation by purchasing bonds and making fresh supply of money in the market, but its efforts solely would not help to tackle with the situation till the government parts with its own share. Liquidity squeeze accompanied by heavy credit demand is likely to result in stoking inflation which is already hovering at the higher levels of 13.33%.
