So I have a tricky question regarding link juice.
My companies website has 35 physical locations throughout the UK. Each location has it`s own social media accounts, local citations and reviews. Each location also has a location landing page on the main website, with a link like www.maindomain.com/locations/keyword-locationname.html
All the social media accounts, local citations and review listings include a direct URL to the main company homepage. In total there are around 2000 back links all pointing to the main domain, with significant authority being passed along. This is great for the homepage, but not so great for the location landing pages - some of which obviously struggle to rank well in competitive locations.
If I were to change all the location social media pages, local citations and review listings to point to URLs of their corresponding location pages, could I harm my overall rankings by redirecting so much authortiy away from the main homepage? Clearly I want the location pages to rank locally and this change would help them do that, but I don`t want to damage the presence of my main brand either.
