One of the most important aspects of creating a web site is Search Engine Optimization or SEO. SEO is a way to help the search engines find and rank your web site based on the content and the structure of your web site. There are a few ways to achieve better search engine rankings, and they are covered below in the quick tips and advice section.
Do Use a robots.txt file
A robots.txt file is a simple text file that gives search engine commands and instructions. You can use it to tell visiting robots to index or not index certain parts of your site, to crawl or not crawl certain pages, to follow or not follow links on your site, and other things.
Essentially, a robots.txt file is a script that you upload to the root of your web site. It is not usually necessary to have one on your root since the search engines will automatically generate one for you. If you do not want to upload a file to your root, various sites will generate code for you that will be a file called robots.txt.
A robots.txt file is only concerned with search engine robots. It will generally be placed in the root directory of your site, and it will affect specific pages of your site.
To generate a robots.txt file in a non-root directory, there are a variety of sites that will provide scripts that will generate the file for you. On such sites, you merely have to type in the URL of the directory you would like to create a file and upload it. On systems that provide you with access to the root of a site, it is usually in the /oom/)bin/ directory. To create your robots.txt file in a root directory, you will need to know some command syntax which will be sure to be explained at the link provided.
The syntax of the robots.txt file is fairly simple. To be able to start the file, you will need to know basic computer programming. There are many online tutorials that you can take advantage of in learning basic computer programming. This will not only help you with setting up the robots.txt file, but it will also ensure that the program created matches the syntax you have typed in. If you are unsure of the file structure, you can always leave a basic example off and let the system figure out the rest.
To be able to get and use the robots.txt file without root access, you will need to know how to access the root directory of a web site. To accomplish this, you would type in the following command line:
In the example above, the commands are the same as in the robots.txt file.
Tip: All files and folders listed in the root directory of a web site are usually automatically indexed and are treated as content by the search engines.
By assigning different rights to different users or groups of users, you can specify who should have access to particular parts of a web site. In other words, you can specify who should read and submit the robots.txt file, or which users should have full access to all files and folders listed in the root directory of the site.
Some web sites recommend that you do not assign multiple robots.txt files to the search engine robots as it can cause performance problems for the search engines. In most cases, this is not a problem, as it is simply a matter of management.
There are other options available on the market. Where those options are concerned, their quality will be directly proportional to the price that they charge. It is then important to consider the cost. If you are going to pay anybody for the solution that will be effective, then it is going to be the most expensive option of all, and perhaps the toughest to implement.
robots.txt does not stop with just assigning different rights to different users. It is a file that contains information about each search engine. It contains specific information about the search engine itself, such as the precise search engine API through which the search engine interacts with the robots. It even contains information on some of the robots that the search engine provides.
In the file named robots.txt, you will have specific commands. If you list the file as robots.txt, then the information placed there becomes publicly available. Through the file located at the root of the site, you can specify that some of the files like index.html, sitemap.xml, and robots.txt will be given fewer credits, resulting in smaller page sizes.
