I have created a site with a silo structure with 5 categories (silos) and about 10 articles in each category.
The problem is that in each article i have a link to my salespage and that link will mess up my silo structure.
I thought about making this link to nofollow but I read that it was a bad idea.
Have also read something about iframes but don't understand it that well
Would appreciate if somebody could give me some advice on how to link within a silo (an article page in a silo) to a page that is outside the whole silo structure.
Thanks in advance
