I want a tool that can check Page Rank on millions of domain names, and export the results into an .xls spreadsheet, ordered by Page Rank, with the Page Rank displayed in a separate column.
The tool must be able to support an unlimited amount of proxies, however should not require proxies (I should be able to check from the local connection only if I wish).
The tool must also have one key functionality that no other tool has (hrefer/seospyglass don't have this feature) - and that is to be able to re-check failed PR checks from a list, without having to recheck every successfully checked domain in the list.
For example, after checking the PR of about 3000 websites, Google will ban PR checking for an IP address. This means that if I have 30 proxies checking 10 million domains, after 90,000 domains are checked, the Page Rank of the remainding domains will come up as "n/a". I want the tool to be able to re-check all these websites that failed to be checked due to the IP being banned, without having to recheck the domains that were already successfully checked.
You should be familiar with the hrefer PR checker and the seospyglass Page Rank checker tools to understand what I'm talking about.
