I already have a website. Now I started another new website. If I place a link to the new website in the footer of every page of old website, will it count as a single backlink or maultiple backlinks. Say my old website has about 25 pages+ over 100 forum pages. So should I count as 1 or 25+ backlinks.

Note :
Old site: http://www.biologyformhtcet.com (approx 4 months old, PR 0, No DMOZ listing, Google has 147 results for site:biologyformhtcet.com)

New site: http://www.mht-cet-online.com

Both sites have related content.

All inputs appreciated.
Thank you!
