Sorry, but we can't offer this tool on external domains anymore. You can still use it here > SEOlogs PAGERANK TOOL
How you do it: Use a 301 redirect from your domain to a high-PR domain. Your domain will eventually get the PR that the target domain has. One way to check it is doing an info:mydomain.com in Google. If the URL shown is different from the domain, it's a good bet the PR is "fake".
You can find Fake pagerank tools around the Web, just use Google and search for a 'fake pagerank tester' Meti
