I have page1.html that is being 302 redirected (temporary redirect) to page2.html page2.html is disallowed in my robots.txt file. Fetch as Bingbot is also a reliable way to test if a URL is being blocked by your robots.txt file. Under normal circumstances, when googlebot encounters a 301 redirect from page1.html to page2.html, it will index page2.html, and when googlebot encounters a 302 redirect from page1.html to page2.html, it will index page1.html The robots.txt file, also known as the robots exclusion protocol or standard, is a text file that tells web robots (most often search engines) which pages on your site to crawl. 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). It is like not having a robots.txt at all. It also tells web robots which pages not to crawl. Robots are often used by search engines to categorize websites. You get the new domain/subdoman and resume normal search for robots.txt as you would have done if user initially said pages.github.com. It works in a similar way as the robots meta tag which I discussed in great length recently.The main difference being that the robots.txt file will stop search engines from seeing a page or directory, whereas the robots meta tag only controls whether it is indexed. After identifying various kinds of duplicate content on your site, it's important to use 301 redirects and robots.txt to clean up your indexed files. The Robots.txt tester tool is designed to check that your robots.txt file is accurate and free of errors.
robots.txt file BEFORE attempting to follow the 301 - once it reads the Disallow: / it then stops and never accesses the 301 at all, meaning the second domain never gets indexed.
First, let’s take a look at why the robots.txt file matters in the first place. A robots.txt file consists of one or more blocks of directives, each starting with a user-agent line. But if Google see 50X status or server side errors, then Google will stop crawling your site, because may be you're busy to configure your server. The “user-agent” is the name of the specific spider it addresses. So you can put a common robots.txt in allsites, but override it any site you want by placing a custom robots.txt in the website root. It’s polite, so sending it to fetch a URL blocked via robots.txt will get …
Thus, Yandex will detect the mentioned directive on the site which needs to be stuck. While Googlebot and other respectable web crawlers obey the instructions in a robots.txt file, other crawlers might not.
However, it will ONLY do this if the robots.txt file doesn't exist on the filesystem at that location. I think we should be a bit more forward leaning and not rely on redirect taking us to a new robots.txt. So do not redirect your robots.txt or if you do then make sure you've block same thing in new site robots.txt The robots exclusion standard, also known as the robots exclusion protocol or simply robots.txt, is a standard used by websites to communicate with web crawlers and other web robots.The standard specifies how to inform the web robot about which areas of the website should not be processed or scanned. Robots.txt is a file that is part of your website and which provides indexing rules for search engine robots, to ensure that your website is crawled (and indexed) correctly and the most important data on your website is indexed first. You can either have one block for all search engines, using a wildcard for the user-agent, or specific blocks for specific search engines. The Robots Exclusion Standard was developed in 1994 so that website owners can advise search engines how to crawl your website. If the robots.txt file says it can enter, the search engine spider then continues on to the page files. Robots.txt directives may not be supported by all search engines The instructions in robots.txt files cannot enforce crawler behavior to your site, it's up to the crawler to obey them. Why the robots.txt file is important. It does this because it wants to know if it has permission to access that page or file. The first thing a search engine spider like Googlebot looks at when it is visiting a page is the robots.txt file.
