As a matter of fact, I would pose a similar inquiry. At pesco online bill, we have a DA of 34 for Ahrefs and a DA of 20 for MOZ. We have top notch backlinks, even one from Wikipedia and some from Amazon Alexa pages. We have gotten 150+ backlinks over the most recent a half year, every one of them with a DA of 50-95. Yet the DA isn't changing a solitary piece. Why would that be??
