Hi, I have a backlink from a high DA/PA Government Website pointing to www.domainA.com which I own and can setup 301 redirects on if necessary. However my www.domainA.com is not used and has no active website (but has hosting available which can 301 redirect). www.domainA.com is also contextually irrelevant to the backlink. I want the Government Website link to go to www.domainB.com - which is both the relevant site and which also should be benefiting from from the seo juice from the backlink. So far I have had no luck to get the Government Website's administrators to change the URL on the link to point to www.domainB.com. Q1: If i use a 301 redirect on www.domainA.com to redirect to www.domainB.com will most of the backlink's SEO juice still be passed on to www.domainB.com? Q2: If the answer to the above is yes -  would there be benefit to taking this a step further and redirect www.domainA.com to a deeper directory on www.domianB.com which is even more relevant?
ie. redirect www.domainA.com to www.domainB.com/categoryB - passing the link juice deeper.
