I have a Pr5 blog. I intend to add to its bloglink my other blogs. However, these blogs tackle topics different from my PR5 blogs. Will they still be benefitting from the link anyway, SEO wise? Hopefully they will.
Only your PR5 blog wud get benefit in terms of SEO and Traffic if your other blogs have gud PR and Traffic. but your other blogs wud not get any benefit from it because it's outbound link.
