A robots.txt file tells search engine crawlers which URLs the crawler can access on your site. This is used mainly to avoid overloading your site with requests; it is not a mechanism for keeping a web page out of Google.

Commands can be set up to apply to specific robots according to their user-agent (such as 'Googlebot'), and the most common directive used within a robots. txt is a 'disallow', which tells the robot not to access a URL path. You can view a sites robots. txt in a browser, by simply adding /robots.

To fix this log into Blogger and go to Settings > Crawlers and Indexing > Enable custom robots. txt, The switch should be ticked OFF and a new robots. txt file will be generated with the correct parameters. There is no reason to do a custom robots.

The “Blocked by robots. txt” error means that your website's robots. txt file is blocking Googlebot from crawling the page. In other words, Google is trying to access the page but is being prevented by the robots.

To block indexing robots, for example, Googlebot or Bingbot, just put the user-agent name into the user-agent line of your robots. txt, just like in the above example: https://example.com/nogooglebot/.
