$ 4 for pr 0, 1, 2, 3, 4 above links
and everybody is asking for PR links but compromise with the quality of links
but Google give importance to quality and relevancy
Ok tell me when you search on Google for a keyword its shows some sites on Ist Page, did you checked those sites pr ??
kindly check those sites pr if PR is everything then every PR 7 and above site should be on Ist page ( so kindly ask why Google not giving those sites Ist position which has PR 7 and above )
Think it
Kind Regards
