My sub-sites have been indexed under my primary multisite domain and I am wondering if I block them all in robots.txt will it in turn affect the sub-sites' mapped domain and their SERP.
I have already 301 redirected the sub-sites to their mapped domains hoping that it will improve SERP, but also stop Google from indexing the subdomains.
If anyone has any experience with Multisite SEO, I'd love to meet you. I've had many a headache over the last 2 weeks. I think a best practice for multisite SEO is on the cards and I would be willing to help put it together.
