I am currently working on improving site authority for a client site. The main site has significant authority, but I have learned that the company owns several other resource-focused microsites which are stagnant, but which have accrued significant page authority of their own (thought still less than the main site). Realizing the fault in housing good content on a microsite rather than the main site, my thought is that I can redirect the content of the microsites to internal pages on the main site as a "Resources" section. I am wondering a: if this is a good idea and b: the best way to transfer site authority from these microsites. I am also wondering how to organize the content and if, for example, an entire microsite domain (e.g. microsite.com) should in fact be redirected to internal resource pages (e.g. mainsite.com/resources). Any input would be greatly appreciated!
