I went on GWT and noticed there are a few URL errors. I thought they were some of my pages I renamed, but 99% of them seem to be links to part of my website that never existed. Most of those links are not even on the same topic of what my website is about. eg. I got a website about health, and it says there is an error with mywebsite.com/something-something-halloween Should I just ignore them, mark them as fixed or do something else?
