What to look for with Domain Authority?
-
Hi,
Our site has fluctuated between 20 and 22 DA for six months, but today it jumped to 27. Is that a sign we are doing something right or is 5 points within the DA's fluctuations pretty standard?
Thanks,
Ruben

Hi Ruben,
It could mean that yes you are doing something right, as in getting more links, or just that moz has recently crawled or found more links, and as result you are seeing a jump in your DA. A 2-5 point increase or decrease is not out of the ordinary

Hope this helps!
