Welcome to the Q&A Forum

Greetings fellow Moz Community, first time asking a question here so kind of excited to be part of the community. I hired an SEO firm about three months ago.  They have arranged high ranking DA guest posts for us as well as many other small low DA links.  None of these links have any kind of a spam score. However for the past two months they have been helping, our website's DA has actually dropped by one point each month. Is this cause for concern?  Any thoughts on how I can trace the drop? On a side-note, out of the 700+ keywords that didn't were ranking in the top 50, about 200 of them now are gone compared to last month.  I don't know if this is related or not, but something looks awry.
