I was wondering if adding http:// into my links was a bad thing for SEO optimization.

I know that is unnecessary but I have several links that are displayed in multiple subdomains.

I try to explain it better:

  • The main site is in http://www.example.com and in every page there are some links to other pages
  • I have, for example, http://search.example.com and http://account.example.com that has the same header with links that point to http://www.example.com

So, my question is, if the spyder goes to http://www.example.com and finds several links that point to http://www.example.com/page1 instead of /page1, ecc. would this hurt indexing?
