I have a page on my site which lists & links to maybe some other sites in the same business [all online bookstores]. In return those sites have basically the same page on their site.
Is this likely to be good or bad for the sites involved? Is there an approximate number of participants where maybe it turns from 'good' to 'bad'?
If it is bad would a 'round robin link list' be any better [A links to B links to C links to A, so maybe three different pages or so]?
