301 redirect and IBL's

[maxseo]

Hi

If I have site and all link point to sub.domain.com and the I implement 301 redirect with mod_rewrite to www.sub.domain.com; do i lose all the ibl's that were pointing to sub.domain.com.

So the question really is; do i start collecting ibl's from the scretch?

They'll come through, but not at full strength. Of course a link to a 301 passes value. How many links go to http://domain.com instead of http://domain.com/ (those do a 301 naturally)? A huge number of our links go to the version without the /, as I expect happens to just about every site.
