Aunque el tema de los enlaces «de pago» ya habia quedado bastante claro en un post anterior, Matt Cutts aclara en una actualización posterior la «permisividad» de Google hacia los directorios de enlaces genéricos:
I’ll try to give a few rules of thumb to think about when looking at a directory. When considering submitting to a directory, I’d ask questions like:
– Does the directory reject urls? If every url passes a review, the directory gets closer to just a list of links or a free-for-all link site.
– What is the quality of urls in the directory? Suppose a site rejects 25% of submissions, but the urls that are accepted/listed are still quite low-quality or spammy. That doesn’t speak well to the quality of the directory.
– If there is a fee, what’s the purpose of the fee? For a high-quality directory, the fee is primarily for the time/effort for someone to do a genuine evaluation of a url or site.
