What to do with unnecessary CMS pages?

I have several CMS collections. Every time you make one, it seems a new page is added to the site. However, sometimes I don’t need that page, so it’s just sat there empty. This seems like it could affect SEO and makes my website messy, so what do I do with them?

I can’t delete them and can’t save them as drafts.

An example… I have a collection called “quotes”. When we get a nice quote from a customer I can create a quote with the name, title and quote text. These quotes are then used throughout the site on pages I do want (for example the landing page). Hence the CMS quote page is never used.

They can be safely ignored. As long as you don’t link to a blank collection template Google will be none the wiser.
