Backlink question

Hi,

I have a website, which is located on some domain and a blog, which is located on subdomain.
My company has a website, which has Pagerank 5 with Reference page, which has Pagerank 4.
The backlink leads from there. Can I expect some improvement in search result positions or not for my blog on subdomain?
Keyword used is a name of my website, nothing specific.

Thank you.

Depending on your keyword competition level. High PR links work great, but if competition is not really low, single link probably won't cause significant increases in rankings.

i recommend building daily at a minimal rate...

you should use different platforms and make sure that your links will be index byG..

well it depend on your work that how you are doing. I say do the maximum quality work for best keyword ranking

are you looking for blog comments on high pr pages, really could not make out from your post.
