I also analyzed a few websites and realized a huge difference in terms of DA. For instance, the website solidhook.ca has a domain rating of 67 on Ahrefs whereas Moz reports 18 (DA). This other website has a domain rating of 31 on Ahrefs but only 14 on Moz. Apparently, Moz bases its tool mainly on Google whereas Ahrefs considers other search engines like Bing. Your site can be performing so well on Bing but not so good on Google, this might be the difference. That's why our website has several posts ranking number one on bing but Moz reports 0 ranking keyword.
