In this write-up, I will with any luck , make some feeling out of all of the previously mentioned 智能機械人.
There are several people out there who vehemently insist on the uselessness of the robots.txt file, proclaiming it out of date, a factor of the previous, simple lifeless. I disagree. The robots.txt file is possibly not in the top 10 approaches to advertise your get-abundant-fast affiliate web site in 24 hours or less, but still plays a major part in the lengthy run.

Let us attempt to determine out some of the lingo.
What is this robots.txt file?
The robots.txt file is just a extremely simple text file (or an ASCII file, as some like to say), with a quite easy set of instructions that we give to a world wide web robot, so the robotic is aware which web pages we want scanned (or crawled, or spidered, or indexed – all conditions refer to the same issue in this context) and which pages we would like to preserve out of lookup engines .
What is a www robotic?
A robotic is a personal computer system that routinely reads net web pages and goes through each link that it finds. The goal of robots is to get details. Some of the most renowned robots pointed out in this write-up perform for the research engines, indexing all the data accessible on the net.
The first robot was produced by MIT and launched in 1993. It was named the World Wide Web Wander and its initial goal was of a purely scientific nature, its mission was to evaluate the development of the web. The index generated from the experiment’s results proved to be an great instrument and efficiently became the first research motor. Most of the stuff we consider these days to be indispensable on the internet instruments was born as a facet influence of some scientific experiment.
What is a lookup engine?
Generically, a research engine is a program that queries through a database. In the popular feeling, as referred to the web, a lookup engine is considered to be a program that has a consumer search kind, which can look for via a repository of world wide web internet pages gathered by a robot.
What are spiders and crawlers?
Spiders and crawlers are robots, only the names seem cooler in the push and in metro-geek circles.
What are the most well-liked robots? Is there a record?
Why do I want this robots.txt file in any case?
A excellent reason to use a robots.txt file is actually the fact that numerous lookup engines, such as Google, submit tips for the general public to make use of this resource. Why is it these kinds of a huge deal that Google teaches folks about the robots.txt? Well, due to the fact presently, research engines are not a playground for scientists and geeks anymore, but massive corporate enterprises. Google is one of the most secretive lookup engines out there. Extremely small is identified to the community about how it operates, how it indexes, how it lookups, how it produces its rankings, and so forth. In fact, if you do a cautious look for in specialized community forums, or wherever else these concerns are talked about, no one really agrees on no matter whether Google puts far more emphasis on this or that aspect to develop its rankings. And when folks don’t agree on factors as precise as a position algorithm, it means two issues: that Google continuously adjustments its methods, and that it does not make it extremely very clear or quite community. There is only 1 factor that I think to be crystal distinct. If they advise that you use a robots.txt (“Make use of the robots.txt file on your web server” – Google Technical Recommendations), then do it. It may possibly not support your ranking, but it will definitely not damage you.
There are other factors to use the robots.txt file. If you use your error logs to tweak and preserve your web site free of errors, you will notice that most errors refer to somebody or anything not obtaining the robots.txt file. All you have to do is produce a simple blank website page (use Notepad in Home windows, or the most simple textual content editor in Linux or on a Mac), name it robots.txt and add it to the root of your server (which is in which your residence page is).
On a diverse notice, these days, all lookup engines appear for the robots.txt file as soon as their robots arrive on your web site. There are unconfirmed rumors that some robots may possibly even ‘get annoyed’ and depart, if they will not discover it. Not confident how accurate that is, but hey, why not be on the protected facet?
Again, even if you will not intend to block something or just never want to hassle with this stuff at all, getting a blank robots.txt is still a great thought, as it can really act as an invitation into your internet site.
Do not I want my web site indexed? Why quit robots?
Some robots are nicely created, skillfully operated, lead to no damage and offer worthwhile provider to mankind (will not we all like to “google”). Some robots are created by amateurs (bear in mind, a robotic is just a system). Poorly written robots can result in community overload, security difficulties, and so on. The base line below is that robots are devised and operated by people and are vulnerable to the human mistake factor. As a result, robots are not inherently poor, nor inherently amazing, and require mindful interest. This is one more scenario the place the robots.txt file arrives in helpful – robotic handle.
Now, I’m positive your main purpose in daily life, as a webmaster or internet site owner is to get on the 1st website page of Google. Then, why in the globe would you want to block robots?
Here are some situations:
one. Unfinished website
You are nevertheless constructing your site, or portions of it, and will not want unfinished web pages to look in research engines. It is mentioned that some lookup engines even penalize sites with web pages that have been “beneath building” for a prolonged time.
two. Stability
Usually block your cgi-bin directory from robots. In most circumstances, cgi-bin is made up of apps, configuration files for people application (that may truly have delicate details), and so on. Even if you never at present use any CGI scripts or programs, block it anyway, greater risk-free than sorry.
three. Privacy
You may well have some directories on your site the place you hold stuff that you never want the complete Galaxy to see, such as images of a good friend who forgot to put clothing on, and so on.
