Welcome to the Q&A Forum

Hi Luis, Since the launch of the Penguin algorithm in 2012 (and for some time before that), over-doing anchor text has been dangerous. It still works for some sites, but the likelihood of being penalised is greatly increased when commercial or non-brand / non-miscellaneous anchor text outweighs brand / miscellaneous anchor text in a backlink profile. Directories were a popular way to build links in "the old days", pre-2009 or 2008. Many people had stopped using directories before then as well. As Richard says, too many links from irrelevant directories is a bad thing. It's super easy for Google to notice and either ignore or penalise. I would be very selective with my choice of which directories I wanted to be listed in and would take a very white-hat approach to directories in general. That is, don't get listed in one that you wouldn't want to be listed in even if you received no link or a nofollowed link. Some say that directory links should be nofollowed for safety - I'm not sure that just being listed somewhere with a followed link is really that dangerous, but it's safe to say that using directories for SEO purposes is not a good tactic in 2014.
