Hi, my website https://mediaonemarketing.com.sg/digital-marketing-services/ has been DA55 for years. Over the years I have faithfully built up a lot of powerful backlinks even from financial times, entrepreneur.com, yahoo news, hubpost, and many many high DA sites by doing guest posting, press releases etc but the DA doesn't change a single bit. How often does MOZ update and what are the criteria? Its very puzzling
