I plan on using wordpress mu to manage multiple sites that are mapped to top level domains. My question is, will using wordpress mu play any part in the rankings of the websites. will seo be affected?
Also, I noticed that all images that I upload are uploaded under site1.mysites.com instead of site1.com. Will this matter in terms of seo for images on site1.com?
Lastly, I am unable to preview posts for my domain mapped websites, is there anyway to fix this?
