suddently think of this today, by using the meta index nofollow, this can prevent the bot from crawling to external site, and thus preventing links to unrelevant site, and to bad neighbourhood as well. is there any proof that this helps page ranking?
Linking to other sites is in your hands, so take care while linking; using nofallow tag you prevent spiders from crawling linking sites they why you have linked to them so Google considered such practice as blackhat and may affect your ranking;
So IMO think twice before linking so that you need not have to use such “ nofallow ”
meta nofollow... will this help site ranking?
