just try with manual check, go to google search and type your domain name that will check, then find the result, if you found url result is yours (your domain name) its real PR (valid) and if you get another url, not yours, that could be fake PR. CMIIW
try manual check that i post above. or you can use online tool like checkpagerank.net or digpagerank.com
hi, that right try to check it through checkpagerank.net or digpagerank.com.I'm pretty sure you will get some idea on how the fake pr look like..
Check it manually by looking at how many backlinks the site has. If a site has no (or very few) backlinks, then it should not have a high pagerank.
by using checkpagerank.net, this checker will give you valid PR. If it not valid, it will give notice
