I used to work daily on my office website https://quintdaily.com/ and  follow link building strategy. however, since more than 40-50 days, there is no movement in my DA, as the PA has just lifted up. However, there is no changes in Domain Authority so far. Besides, other than this website, im working on location wise SEO projects, but, i can find those websites Domain Authority changed in less 20 days. Is there is time period in changing the Domain Authority once it touched DA 30+?
