Does anyone know why my website's domain authority has dropped from 51 to 49

However this does not seem to be in isolation. All of my competitors websites have taken a similar 1 or 2 points hit.

I am thinking that as an industry we may have been affected by a mutual linking site being taken down, redesigned or just loosing its own domain authority.

We do rank well for our keywords and we have been on a continual rise since I took over in January, we do a little bit of a guest blogging and I am trying to build links to the site but I am doing it slowly.

Would anyone else have an idea on what has happened that would cause 4 sites in the same industry to take a 1 or 2 point hit?

Thanks,

Emmet

We released a new index last night, and DA should be closer to normal now. Can you take a look and let me know how things are now?

Hi Keri,

Our industries Domain Authority took another tumble when I checked this morning. Is this related to the same changes?

We are now back to 47 which wipes out all of the gains we made in 2013.

Thanks for your continued support on this.

Thanks very much for the prompt and very precise answer. I will continue to try and build our Domain authority and hope that we can gain on the competition in the next update.

Hi! I do know why things have dropped. We released a new index last week, and it was a little bit smaller than the previous index. A smaller index means seeing fewer links, and thus less domain authority. It's nothing to worry about, since everyone went down about the same amount.
