I got an EMD domain without checking its history first (keyword.org). Then I checked it on archive.org and found out it had huge keyword density in the past and probably was penalized because of this. I found no backlinks using ahrefs. Now the site doesn't rank for allintitle nor for a non quoted text snippet. The domain was indexed about 3 days ago. It does rank for quoted snippet but not for quoted title. Should I change the domain and get a PMD instead of this EMD?
