I've never had occasion to look at it before, but I know some folks on here are interested in the PA and DA authority of expired domains. Is there any sort of rule of thumb regarding the value of domains with a particular PA/DA score? For instance, a minimum price or range of prices domains with a given score would fetch on the aftermarket? And is there anything else to watch out for (other than obvious trademarks in the domain) - i.e. does the string in the domain name matter, or are DA/PA domain buyers only interested in the DA/PA score? Thanks in advance for any light you can shed on this!
