Thanks for your reply Everett, that definitely answers the main part of my question,

I'd be interested if anyone has any experience in using the Confluence add-ons for SEO?

I think this is a difficult question so apologies in advance and any help would be appreciated!

We currently have a large amount of support center content sitting on our main pages which we don’t think is very effective (mainly basic how to guides). We think it is difficult for visitors to understand and the UI is very poor. In order to solve this we’re currently moving this content onto a subdomain using Confluence, a wiki based team collaboration tool (from a company called Atlassian).

What we’re planning on doing is very much like what Atlassian themselves have done on this page: https://confluence.atlassian.com/display/ALLDOC/Atlassian+Documentation

What are the SEO issues / dangers that I need to consider before moving this content? I’m assuming that as this content will still be on the same domain then we can minimise link equity / authority loss by setting up re-directs to the new content. Also, has anyone had any experience of using Confluence and whether individual pages can be optimised for SEO? I notice that there are lots of add-ins that can be used, one of which is an SEO add-on which allows you to customise things like meta description tags.
