my site in google directory was ranked PR4 , now today i see that there is no PR appearing near my domain listed in google directory ( i am near the last position), but my browser toolbar shows me PR4, i like to know whether my PR becomes "0" . because my SERPS ranking also getting worse day by day, Is there is any connection betweeen google directory and SERPS, my site is a white hat site and i follow all google terms, but my competitors doing keyword stuffing and other tricks and they are still in the first position.
What would be the reason for no PR details in google directory for my site. If you have any suggestions please let me know.
thanks
