All URLs in my WordPress site can be visited via browser such as FireFox and Chrome successfully. However, today I receive emails from Google Ads telling me that some of the URLs have errors. The error code is HTTP error:403.
So I just doubt that is it possible that some URLs can be accessed via Browser, but cannot be accessed by Google Robot? If yes, then is there a way to find or test such URLs?
My site using WordPress, there are some redirects in the URL, also I remove the category from the permalink. All these may be the cause of the problem?
