This tool allows you to upload from file a list of proxies and a list of urls you want to check. Or you can enter them manually one by one. When you have entered your proxies list you need to click the Check Proxies button and select the Use Proxies checkbox (if you want to use proxies for checking). This will verify which proxies are live and only use those when checking PR. You can then check the PageRank of your urls. Once completed you can also export your results to csv for your records. Please note that when you are uploading proxies and url lists, that it should be only only proxy and one url per line and it should be a text file.
