So I suppose, everybody heard that Google is not going to update toolbar PageRank in the future. Even if PR was mostly rudimentary metrics for vast majority of SEO community it was at least pretty convinient to generally differentiate some groups of backlink pages with it. PR was just one of many site classification factors. But still, it was the most distinguished and remarkable one. Anyway, PR will be absolutely useless in the nearest future. So I want to ask you guys what "main classificator" type of metrics you use now/plan to use in future? I believe that moz DA/PA are in favor, but this is combination of parameters. Having one major clasificator brings more ease and intuitive understanding to whole link building. So what parameter do you use now instead of PR?
