Hi
I recently saw my DA authority drop from low 30s to high 20s by about 6 or 7 points. I'm not sure what may have caused this drop but I do know that I was pushed (by senor colleagues) to accept an inbound link from a new directory website which had a very low DA as just launched and a spam score in Moz of 7. Would this one new link have such an impact on our DA and what implications does this drop create for our overall SEO and metrics?
