Evo sta sam Google
kaze.
Izdvajam:
Crawl prioritization: Search engine robots can't sign in or register as a member on your forum, so there's no reason to invite Googlebot to follow "register here" or "sign in" links. Using nofollow on these links enables Googlebot to crawl other pages you'd prefer to see in Google's index.
However, a solid information architecture — intuitive navigation, user- and search-engine-friendly URLs, and so on — is likely to be a far more productive use of resources than focusing on crawl prioritization via nofollowed links.
U vezi misljenja da bi mali sajtovi imali vise koristi od nofollow, meni se cini da je tu situacija upravo obrnuta. Sto vise kvalitetnog sadrzaja, to bolje a nema razloga da se na pr. About us stranica gurne u stranu kad moze sadrzajem i interlinking-om znacajno da doprinese opstoj stvari.
