SEO Best Practices:

Blocking a Domain Page:

There are a few methods which help to block search engines from getting access to a particular domain.

Block with robots.txt:

This instructs the search engine not to crawl the provided URL. On the other hand, keep it in index and display in search results.

Block With Nofollowing Links:

A poor method to use and not recommended. Using this way, the search engines can find pages through toolbars of browser, links from various pages, analytics etc.

URLs blocked due to robots.txt errors:

Google was not able to crawl the URL because of a robots.txt confinement. This can happen for various reasons. For example, your robots.txt file may deny the Googlebot totally; it may restrict access to the registry in which this URL is found; or it may preclude access to the URL particularly. Frequently, this is not an error. You may have particularly set up a robots.txt file to keep us away from crawling this URL. On the off chance that this is the situation, there’s no compelling reason to settle this; we will keep on respecting robots.txt for this file.
