I have been using Google Shopping now for 2 years and have never had any issues. Last night however items were being disapproved from my site for the following reasons:
Product pages cannot be crawled with a mobile user-agent due to the robots.txt restriction
Product pages cannot be crawled because of robots.txt restriction
The solution that Google have given involves adding the following to the Robots.txt file
However I cannot amend the Robots.txt file.
Would anyone have any ideas on this?
Your details are a bit vague so this may be off the mark but if you can't edit the file directly on your hosting platform, you should be able to download it to your local computer via FTP. Then make the edit and reupload it back to your hosting platform. I would recommend making a backup of the file before editing.
Hope that helps.
