I'm a bit confused here, but what do you mean by DA45+? DA60+? Do you provide complete report for this? And what are the PR's of these packages only for DA45+ to DA60+?
DA is a metric that is different than pagerank. It calculates total number of IPs linking to a website , pagerank of those links, total links into the linking site and more metrics than the standard google pagerank algo.
The Pagerank of our DA45-DA60 sites range from PR0 to PR3. This is because of the way we use htaccess on our domains to redirect old links back to the root directory. From the research I've done these domains will range from PR3 to PR7 on the next update, however the authority as Google is concerned is already there as true pagerank/website authority is calculated in real time rather than every 6 months as the toolbar would have you to believe. I can provide a full report to long term/high itrader members here, however those with lower posts/itraders won't get a full report.
Hope this makes sense.
Here's a few Ahrefs examples.
Out DA60+ domain - 752 total links from 278 IPs according to AHREFs. Domain authority is 62.92 and SEOmoz page score is 69.33 with a mozrank of 5.09. Google.com shows a total of 860,000 links to the domain in some form or fashion. I expect it to easily be a PR7 on the next update as some PR8s out there only have PA scores of 60 to 65.
One of our DA50+ domains has 11,900 links according to google, Domain authority score of 54.02. I expect on the next update it should be in the area of PR5 or maybe even PR6. It is currently a PR2 , so as far as pagerank is concerned it is 'stronger' than the DA60+ site, but in reality the DA60+ site has over 80 times the links.
So , long story short - Selling links based on pagerank sucks, but it's what buyers want, so we offer both. The established, long term SEO companies are ordering more DA links than anything else, and I think it's the right choice.
