Hello all, I have an online business directory (2 months old, PR0) which has 30 companies with their website url. Should i use a nofollow for the urls or it doesnt bother my pagerank? Company Pages are > PR1 thanks George
All depends on the status of the other sites. Even if one of those websites have been banned or penalised by Google, your site will be linking to a 'bad neighborhood', which will affect you in the SERPs and lower your SEO value in every aspect.
Until now the only thing I know about do follow and no follow, is that no follow is bad/ need to ignore, and do follow is good
