Hi guys, I am thinking about increasing the domain authority by submitting it to one of the paid web directories? The thing is, after Panda, we all know that authority of the domain matters a lot (at least I see it according to SERP changes in my niches). So I am thinking about some additional ways how to increase the authority of a domain as a whole. My sites are mainly informative, 100+ pages all the time, each inner page targeting different keywords. My thought is that maybe a submission to dir.yahoo.com or business.com (each costs $300/year) may increase the domain authority as a whole, what would mean that the SERP of inner pages for particular keywords will improve side-wide. Did any of you tried this? Thanks in advance for your feedback.
