A robots.txt generator is a tool available online that you can use to generate your own robots.txt file for website use. Take note that the robots.txt file is not an html file but a text file. You can put this into your website in order to inform search bots which pages you like them to visit and which ones you do not want them to visit. A robots.txt file works because this file is the first one that search bots look for upon arriving at a website. They then read this file to gather directions while crawling a website. The directions will indicate to them which pages they can crawl as well as those that they cannot crawl.
To Be Found by Web Crawlers
In order for a robots.txt file to work correctly, you must place it in the main directory or root domain of your website. Otherwise, search bots and other web crawlers will not be able to locate it in your website. When that happens, they assume that your website does not have a robots.txt file and they will proceed with crawling the entire contents of your website, even crawling those pages you do not want for them to index.
The Structure of a robots.txt File
A robots.txt file has a simple structure. Although this simple structure is still very flexible. The basic structure of a robots.txt file is composed of two syntaxes: the user agent syntax and the disallow syntax. In the user agent syntax, you specify the web crawler or the search bot and then on the disallow syntax, you indicate the specific pages of your website that you do not want to be indexed by those web crawlers and search bots you have indicated in the user agent syntax.
Some Traps to Always Keep In Mind
It is very important to keep in mind that once your robots.txt file has gotten complicated, you can fall into several traps. Such traps are primarily composed of contradicting directives and typographical errors. Contradicting directive will confuse web crawlers as to which pages should they index and which should not be indexed. Confusion can lead to them just going through the web pages. On the other hand, typographical errors like wrong spelling for directories and user agents can lead to failure of the robots.txt to not permit some web crawlers from crawling through some web pages. So to prevent such things from happening, you should always proofread your robots.txt file to look for contradicting directives and typographical errors.
Regardless, a robots.txt file is still one of the most useful text files that you incorporate into your website. To create one that you can use right now, you can use the tool called the robots.txt generator.
