Are you facing such type of robots.txt problem?

Hello SEOs. This is my first question and I hope I will get correct and effective answer.

In W3 Link Checker, I found error following error.

Code: (N/A)
What to do: The link was not checked due to robots exclusion rules. Check the link manually, and see also the link checker documentation on robots exclusion.

What does that error mean? Provide me best solution to resolve this problem. If possible then check our site in W3 link checker and solve the issues. For that, you can check this link.
