Thank you for this response. This helps me a ton as I discuss with our web team on the best way to set the coding for the site so that we are not registering errors but also not hurting the actual site in any way.

I hope I am explaining this correctly. If I need to provide any clarity please feel free to ask. We currently use a domain mask on an external platform that points back to our site. We are a non-profit and the external site allows users to create peer-to peer fundraisers that benefit our ministry. Currently we get many meta issues related to this site as well as broken links when fundraisers expire etc. We do not have a need to rank for the information from this site. Is there a way to index these pages so that they are not a part of the search engine site crawls as it relates to our site?
