I have been searching for dropped domains and the best I have gotten are around TF20/CF20. I know that only TF and CF are not good enough metrics to decide if the domain is good, the backlink portfolio is the most important. But when talking about TF and CF then what would be a good solid domain that would get easy kw-s on page 1 (around 10 PBN for example, I know that "easy" is also subjective). Is TF20/CF20 too weak and should I search for considerably stronger ones? Thank you!
