The Robot Exclusion Standard, also known as the Robots Exclusion Protocol or robots.txt protocol, is a convention to prevent cooperating web spiders and other web robots from accessing all or part of a website which is otherwise publicly viewable. Robots are often used by search engines to categorize and archive web sites, or by webmasters to proofread source code. The standard is unrelated to, but can be used in conjunction with, Sitemaps, a robot inclusion standard for websites.

If you aren't in the know, search engine is not as smart as what you think it is. It can't tell which pages of your site should be included in the index and which files to ignore. Therefore we need.

What is a robots.txt file for websites?
Q. I am looking into SEO for my website and found something called a robots.txt file for spiders and bots. I guess it tells search engines how to cache your site? Anyone have a good explanation? And in my text file why would I disallow the robots? I'm just a little confused. thanks for your help

A. This will not improve your placement in search engines, robots.txt is used to dissallow certain areas of your site, and/or to link a sitemap. If you are serious about SEO, then i suggest to first and formost improve your content. But you should also make sure to include potential keywords in your content, as well as in the header and title of your page. See also: - The H1 to H6 Tags - The TITLE Tag Getting as many inbound links as possible is also important, for them to be as valuable as possible, they should come from websites with relevant content to yours. Inbound links from pages with higher PageRank may be rated higher by google, then links from lesser ranked sites. It will not harm your site if you get links from "bad… [cont.]

What does a robots.txt file do?
Q. I had my site checked and the program said to use a robots.txt file - I dont know what it is or how to make it..can anyone help? I promise to give the best answer 10 points
Asked by cyndisource - Mon Oct 2 07:11:29 2006 - - 6 Answers - 0 Comments

A. A robots.txt is a file placed on your server to tell the various search engine spiders not to crawl or index certain sections or pages of your site. You can use it to prevent indexing totally, prevent certain areas of your site from being indexes or to issue individual indexing instructions to specific search engines. All search engines, or at least all the important ones, now look for a robots.txt file as soon their spiders or bots arrive on your site. So, even if you currently do not need to exclude the spiders from any part of your site, having a robots.txt file is still a good idea, it can act as a sort of invitation into your site. There are many good, free sites that help you create a robot.txt file: here are a couple: Make… [cont.]

Robots.txt File in Netscape?
Q. For some reason when you go to our website in Netscape a dialog opens and asks what you want to do with the robots.txt file, save or open. The file is in the root of my site like it is supposed to be. I have two other sites that have them and don't do the same thing. I even deleted the file to see if the message went away and it doesn't. Any ideas on what could be causing this odd message?

A. Try clearing your history, it may be a freak history link or cookie causing this. I had similar on Firefox, a site I had edited through a browser vnc connection kept offering to open any php pages I went to, it could not actually open them in edit mode, but it tried. Clearing link and cookie history cured it.
