Hello, I wanted the community's advice on how to handle old subdomains. We have https://www.yoursite.org. We also have two subdomains directly related to the main website: https://www.archive.yoursite.org and https://www.blog.yoursite.org. As these pages are not actively updated, they are triggering lots and lots of errors in the site crawl (missing meta descriptions, and much much more). We do not have particular intentions of keeping them up-to-date in terms of SEO. What do you guys think is the best option of handling these? I considered de-indexing, but content of these page is still relevant and may be useful - yet it is not up to date and it will never be anymore. Many thanks in advance.
