Translations:Manual:Nofollow/6/en

Using nofollow will prevent a wiki's links to other sites from boosting those sites' search engine pagerank, which is bad if the wiki owner wanted to boost their pagerank. Turning off nofollow is especially a good idea if you run a private wiki (i.e. one that does not allow editing by anonymous users, and that allows registration by invitation only). In such a case, spamming is not a concern because the spammers lack access to edit. Some public wikis also avoid using nofollow because they want to encourage people to make useful contributions that add external links to their favorite sites. Another cost of nofollow is that there is not yet much capability for using it selectively; it has been argued, "Can you imagine a web that works as good as today's if every link was tagged with nofollow?"
