What is robots.txt? Robots.txt file serves to provide valuable data to the search systems scanning the Web. Before examining the pages of your site, the searching robots perform verification of this file. Due to such procedure, they can enhance the efficiency of scanning. This way you help searching systems to perform the indexation of the most important data on your site first. But this is only possible if you have correctly configured robots.txt.
Just like the directives of robots.txt file generator, the noindex instruction in the meta tag robots is no more than just a recommendation for robots. That is the reason why they cannot guarantee that the closed pages will not be indexed and will not be included in index. Guarantees in this concern are out of place. If you need to close for indexation some part of your site, you can use a password to close the directories.
Why do you need robots.txt? It is such a popular question, but the answer is more than simple. If your website has no robot txt file, your website will be crawled entirely. It means that all website pages will get into the search index which can cause serious problems for SEO.
User-Agent: the robot to which the following rules will be applied (for example, “Googlebot”). The user-agent string is a parameter which web browsers use as their name. But it contains not only the browser`s name but also the version of the operating system and other parameters. Due to user agent you can determine a lot of parameters: the name of operating system, its version; check the device on which the browser is installed; define the browser`s functions.
Disallow: the pages you want to close for access (when beginning every new line you can include a large list of the directives alike)
Every group User-Agent / Disallow should be divided with a blank line. But non-empty strings should not occur within the group (between User-Agent and the last directive Disallow).
Hash mark (#) can be used when needed to leave commentaries in the robots.txt file for the current line. Anything mentioned after the hash mark will be ignored. When you work with robot txt file generator, this comment is applicable both for the whole line and at the end of it after the directives.
Catalogues and file names are sensible of the register: the searching system accepts «Catalog», «catalog», and «CATALOG» as different directives.
Host: is used for Yandex to point out the main mirror site. That is why if you perform 301 redirect per page to stick together two sites, there is no need to repeat the procedure for the file robots.txt (on the duplicate site). Thus, Yandex will detect the mentioned directive on the site which needs to be stuck.
Crawl-delay: you can limit the speed of your site traversing which is of great use in case of high attendance frequency on your site. Such an option is enabled due to the protection of robot.txt file generator from additional problems with an extra load of your server caused by the diverse searching systems processing information on the site.
Regular phrases: to provide more flexible settings of directives, you can use two symbols mentioned below:
* (star) – signifies any sequence of symbols,
$ (dollar sign) – stands for the end of the line.
This instruction needs to be applied when you create a new site and use subdomains to provide access to it.
Very often when working on a new site, Web developers forget to close some part of the site for indexation and, as a result, index systems process a complete copy of it. If such a mistake took place, your master domain needs to undergo 301 redirect per page. Robot.txt generator can be of great use!
Peculiarities to take into consideration when using this directive if you are constantly filling your site with unique content:
because a great many unfair webmasters parse the content from other sites but their own and use them for their own projects.
If you don’t want some pages to undergo indexation, noindex in meta tag robots is more advisable. To implement it, you need to add the following meta tag in the section of your page:
<meta name=”robots” content=”noindex, follow”>
Using this approach, you will:
Robots txt file generator serves better to close such types of pages:
When you generate robots.txt file, you need to verify if they contain any mistakes. The robots.txt check of the searching systems can help you cope with this task:
Sign in to account with the current site confirmed on its platform, pass to Crawl and then to robots.txt Tester.
This robot.txt test allows you to:
Sign in to account with the current site confirmed on its platform, pass to Tools and then to Robots.txt analysis.
This tester offers almost equal opportunities for verification as the one described above. The difference resides in:
First of all, it`s all about crawling budget. Each site has own crawling budget which is estimated by search engines personally. Robots.txt file prevents your website from crawling by search bots unnecessary pages, like duplicate pages, junk pages and not quality pages. The main problem is that the index of search engines gets something that should not be there – pages that do not carry any benefit to people and just litter the search.
But how can it harm SEO? The answer is easy enough. When search bots are getting to the website for crawling, they are not programmed to explore the most important pages. Often they scan the entire website with all its pages. So the most important pages can be simply not scanned due to the limited crawling budget. Therefore Google or any other search engine starts to range your website regarding information it has received. This way, your SEO strategy is in danger to be failed because of not relevant pages.
