301 redirects and backlinking

[Tiger]

I'm doing some SEO work on my website.

The previous url of the website was www[dot]domain[dot]com, however the site was moved to www[dot]domain[dot]com/subfolder

I set up a 301 redirect on www[dot]domain[dot]com to point to the new URL (toolbar pagerank now reflects this also).

However the google SERPS despite being updated with new title and header etc still points to the old www[dot]domain[dot]com URL

www[dot]domain[dot]com has all the backlinks to it..

I'm going out to build some more backlinks and was wondering should I point it to [www[dot]domain[dot]com or www[dot]domain[dot]com/subfolder

Thanks

Ok let me answer my own question for the benifit of others, as I have done SEO and figured it out for myself.

old homepage in "/" url has 600 backlinks.

I set a 301 redirect onto "/en/gb/" page and built about 200 backlinks onto the new page.

Google has understood what is happening moved pagerank onto /en/gb/ and obviously transferred the backlink profile onto /en/gb/ as well.

Before we were #28 now we're #8 with the 200 or so high quality backlinks I've got. On a search term with over 1M global searches and about 140K UK searches (we're #8 on google uk only)

I was a bit confused because market samurai doesn't check for 301 redirects and only regards BLP that specifically link to that particular page.
