I have this question because the most recent algorithm changes by Google have affected my website traffic.
I've been wondering why my homepage PageRank has dropped from 6 to 4 (I am not sure exactly). I am not using any special SEO tools like SEOMOZ, Majestic SEO, etc.
So it's quite difficult for me to ensure whether the page rank has been really affected or not. So can anyone please provide any good resource, tact or tricks to address this question?
