Hi Andre,
Our sub-domains has the activity like forums where lot of users are participating. It's hard to control it with broken links, external links and some spammy content. So we are interested to move the "optimised" sub-domains to sub folders and leave the others. And if the page title repeats in pages of sub-domain, is that bad and dilutes the website transparency? For all our website pages we have give "topic name | brand & keyword" and same for sub-domain pages like "topic name | brand & keyword". Is this hurting us? Having keyword along with brand name across the sub-domain pages hurt rankings?
Thanks
