Before a month, I have made a small analysis and redirect the subdomain to a newly born web page that has no page authority, no links and no history. The subdomain I redirected had some links from bookmarkings, blogs and an article. Let’s see how it worked for me!
I have targeted 2 medium competitive keywords for a subdomain http://manchester.yellowgrid.co.uk both of them reached on the page 2 within a month. After convincing the client for an experiment I made a 301 redirection from the subdomain to a page here http://www.yellowgrid.co.uk/manchester-support.html and result was awesome. Keywords did well in SERPs, 1 is on the first page (10th Position) and other was on the 2nd page with some rankings upward.
This is the result for Google.co.uk – the whole link juice passed to the new page without any difficulty and within 4 days I have got the rankings for the new page.
