DR in ahref doesn’t really mean Google or Bing has the same DR given to you. It’s their algorithm. SEMrush would have a different number for your site. Not saying you shouldn’t check this number at all but always look at it as a directional metric than absolute metric Focus on doing the right things and your score and traffic automatically grows. Submission to relevant directories are indeed right thing to do but don’t stop there. Write content, make videos, comment on Reddit etc
